swaitsandClaude Opus 4.6 3102fc747a feat: add display UI with splash screen, dashboard, and RSSI sparkline 
Implement full SSD1306 OLED display support:
- Splash screen on boot (1.5s) with project name, version, board
- Dashboard showing radio state, config, counters, RSSI/SNR
- RSSI history sparkline (64-sample ring buffer, 2px-wide bars)
- DisplayOn/DisplayOff host commands routed via dedicated channel
- Pure render functions against generic DrawTarget (no hardware coupling)
- Display on/off control bypasses radio task entirely

# Version 1.29.0 (2025-02-26)
* The crate now requires rustc version 1.83.0 or later.
* The following methods were added to all fixed-point numbers, to the
[`Fixed`][tf-1-29] trait, and to the [`Saturating`][s-1-29],
[`Wrapping`][w-1-29] and [`Unwrapped`][u-1-29] wrappers:

* The [`cast_unsigned`][f-cu-1-29] method was added to all signed fixed-point
numbers, to their [`Saturating`][s-1-29], [`Wrapping`][w-1-29] and
[`Unwrapped`][u-1-29] wrappers, and to the [`Fixed`][tf-1-29] trait.
* The [`cast_signed`][f-cs-1-29] method was added to all unsigned fixed-point
numbers, to their [`Saturating`][s-1-29], [`Wrapping`][w-1-29] and

# Version 1.25.1 (2024-02-06)
* Bug fix: formatting numbers with [`LowerExp`] and [`UpperExp`] was producing
incorrect output when rounding incremented a zero in the middle of a string,
for example `format!("{:.2e}", I16F16::lit("9.099"))`.
# Version 1.25.0 (2024-02-05)
* Bug fix: formatting numbers with [`LowerExp`] and [`UpperExp`] was producing
incorrect output for very small numbers, for example
`format!("{:e}", I16F16::DELTA)`.
* Bug fix: formatting numbers with [`LowerExp`] and [`UpperExp`] was panicking
for some cases of positive exponents and small precision, for example
`format!("{:.1e}", I16F16::from_num(1001))`.
* Bug fix: formatting numbers with [`LowerExp`] and [`UpperExp`] was producing
incorrect output when rounding adds a more significant digit, for example
`format!("{:.1e}", I16F16::lit("0.999"))`.
* The [experimental][feat-exp-1-25] `borsh` feature was promoted to an
[optional feature][feat-1-25], and the optional [*borsh* crate] dependency
was updated to [version 1.0][borsh-1-0].

# Version 1.23.1 (2023-03-14)
* Bug fix: comparison of signed and unsigned numbers where the signed number
was wider than the unsigned number was truncating bits from the signed
number ([issue 57]).
* The [*half* crate] dependency is now satisfied by [version 1.8][half-1-8] as
well as [version 2][half-2].

# Version 1.23.0 (2023-02-06)
* String parsing of binary, octal and hexadecimal strings now supports base-2
exponents starting with the separator “`p`” or “`P`”.
* Bug fix: [`int_log10`][f-il10-1-23], [`int_log`][f-il-1-23],
[`checked_int_log10`][f-cil10-1-23] and [`checked_int_log`][f-cil-1-23] were
panicking or returning incorrect values for fixed-point numbers with no
integer bits.

# Version 1.22.1 (2023-01-26)
* The errors from the [`lit`][f-l-1-22] method have been improved.
* The `track_caller` attribute is now applied to many more inline functions
that can panic.
# Version 1.22.0 (2023-01-25)
* String parsing now supports an optional exponent for all supported radices.
* The [`lit`][f-l-1-22] method was added to all fixed-point numbers. This is
useful to write fixed-point numbers literally in code and also works in
constant context.
* All fixed-point numbers now implement [`LowerExp`] and [`UpperExp`].
* The [`Fixed`][tf-1-22] and [`FixedBits`][fb-1-22] traits now have the added
supertraits [`Binary`], [`Octal`], [`LowerHex`], [`UpperHex`], [`LowerExp`]
and [`UpperExp`].
* The [`Wrapping`][w-1-22] and [`Unwrapped`][u-1-22] wrappers now implement
[`Binary`], [`Octal`], [`LowerHex`], [`UpperHex`], [`LowerExp`] and
[`UpperExp`].
* The implementation of [`Debug`] for fixed-point numbers now has more relaxed
constraints on the fractional bits generic parameter: now `Frac` only needs
to implement [`Unsigned`][uns-1-22].

[`Unsigned`][uns-1-21].
* Better code should now be generated when comparing a fixed-point number to
another fixed-point number.
* The following methods were added to the [`F128`][f128-1-21] struct:
* [`min`][f128-min-1-21], [`max`][f128-max-1-21]

* The [`TRY_NEG_ONE`][tfs-tno-1-20] associated constant was added to the
[`FixedSigned`][tfs-1-20] trait.
* The [`const_from_fixed`][f-cff-1-20] and [`const_from_int`][f-cfi-1-20]
methods were added to all fixed-point numbers.
* The [`const_fixed_from_int`][cffi-1-20] macro is now deprecated.
* The following associated constants were added to the [`F128`][f128-1-20]

# Version 1.19.0 (2022-08-29)
* Bug fix: comparison of and conversion from subnormal floating-point numbers
to fixed-point numbers were off by a factor of 2.
* The following associated constants were added to the [`FixedBits`][fb-1-19]
trait:
* [`MIN`][fb-mi-1-19], [`MAX`][fb-ma-1-19]
* [`IS_SIGNED`][fb-is-1-19], [`BITS`][fb-b-1-19]
* [`FixedEquiv`][fe-1-19] is now a supertrait of the [`FixedBits`][fb-1-19]
trait.
* [`FixedBits`][fb-1-19] now has more supertraits from the [*num-traits*
crate] if the [`num-traits`][feat-exp-1-19] experimental feature is enabled.

# Version 1.18.0 (2022-08-19)
* Bug fix: checked division methods were panicking when dividing
[`MIN`][f-m-1-18] by <code>-[DELTA][f-d-1-18]</code> for fixed-point numbers
with zero integer bits, that is when all bits are fractional bits ([issue
51]).
* The following methods were added to all fixed-point numbers, to the
[`Fixed`][tf-1-18] trait, and to the [`Wrapping`][w-1-18] and
[`Unwrapped`][u-1-18] wrappers:
* [`int_log`][f-il-1-18], [`checked_int_log`][f-cil-1-18]
* The [`F128`][f128-1-18] struct was added to replace the
[`F128Bits`][f128b-1-18] struct which is now deprecated. [`F128`][f128-1-18]
has standard floating-point ordering and various classification methods and
associated constants.
* The [`from_str_dec`][u-fsd-1-18] method was added to the
[`Unwrapped`][u-1-18] wrapper.
* The [`Contiguous`][bm-c-1] trait from the [*bytemuck* crate] was implemented
for all fixed-point numbers, added as a supertrait to the [`Fixed`][tf-1-18]
trait, and implemented for the [`Wrapping`][w-1-18] and
[`Unwrapped`][u-1-18] wrappers.

# Version 1.13.1 (2022-03-04)
* The [`const_fixed_from_int`][cffi-1-13] macro now accepts a visibility
qualifier ([merge request 10]).
# Version 1.13.0 (2022-02-22)
* The [`AddAssign`], [`SubAssign`], [`MulAssign`], [`DivAssign`],
[`RemAssign`], [`BitAndAssign`], [`BitOrAssign`] and [`BitXorAssign`] traits
for <code>[Wrapping][w-1-13]&lt;F></code> and
<code>[Unwrapped][u-1-13]&lt;F></code> are now also implemented with `F` as
the type of the right-hand side operand.
* Bug fix: compilation with certain flags was hanging for the thumbv6m target
because of a [rustc/LLVM issue][rust issue 75045]. This version should not
trigger the rustc/LLVM issue ([issue 45]).

# Version 1.11.0 (2021-11-24)
* The following methods were added to all fixed-point numbers, to the
[`Fixed`][tf-1-11] trait, and to the [`Wrapping`][w-1-11] and
[`Unwrapped`][u-1-11] wrappers:
* [`lerp`][f-l-1-11]
* [`inv_lerp`][f-il-1-11]
* The following methods were added to all fixed-point numbers and to the
[`Fixed`][tf-1-11] trait:
* [`checked_lerp`][f-cl-1-11], [`saturating_lerp`][f-sl-1-11],
[`wrapping_lerp`][f-wl-1-11], [`unwrapped_lerp`][f-ul-1-11],
[`overflowing_lerp`][f-ol-1-11]
* [`checked_inv_lerp`][f-cil-1-11], [`saturating_inv_lerp`][f-sil-1-11],
[`wrapping_inv_lerp`][f-wil-1-11], [`unwrapped_inv_lerp`][f-uil-1-11],
[`overflowing_inv_lerp`][f-oil-1-11]
* The [*typenum* crate] dependency was updated to [version
1.14][typenum-1-14].
* The [`LeEqU8`][leu8-1-11], [`LeEqU16`][leu16-1-11], [`LeEqU32`][leu32-1-11],
[`LeEqU64`][leu64-1-11] and [`LeEqU128`][leu128-1-11] traits no longer have
a direct `'static` constraint, as it is a constraint of their supertrait
[`Unsigned`][uns-1-11] since typenum [version 1.14][typenum-1-14]. This
fixes a potential compatibility issue introduced in version 1.9.0.
* An experimental feature was added to enable serialization using the [*borsh*
crate] ([merge request 9]).

# Version 1.10.0 (2021-08-23)
* The crate now requires rustc version 1.53.0 or later.
* <code>{[Div][`Div`],[DivAssign][`DivAssign`],[Rem][`Rem`],[RemAssign][`RemAssign`]}\<[NonZeroU32][`NonZeroU32`]></code>
are now implemented for [`FixedU32`][fu-1-10], and similar for all other
unsigned fixed-point numbers.
* <code>{[Rem][`Rem`],[RemAssign][`RemAssign`]}\<[NonZeroI32][`NonZeroI32`]></code>
are now implemented for [`FixedI32`][fi-1-10], and similar for all other
signed fixed-point numbers.
* The new [`arbitrary`][feat-1-10] optional feature was added to implement the
[`Arbitrary`][a-a-1] trait provided by the [*arbitrary* crate] for all
fixed-point numbers ([issue 37]).

# Version 1.9.0 (2021-05-13)
* Fixed-point numbers can now be formatted as hexadecimal with [`Debug`]
similarly to primitive integers, for example formatting with `{:X?}` will
produce upper-case hexadecimal fixed-point numbers.
* The following methods were added to all fixed-point numbers, to the
[`Fixed`][tf-1-9] trait, and to the [`Wrapping`][w-1-9] and
[`Unwrapped`][u-1-9] wrappers:
* [`is_zero`][f-iz-1-9]
* [`dist`][f-d-1-9]
* The following methods were added to all fixed-point numbers and to the
[`Fixed`][tf-1-9] trait:
* [`checked_dist`][f-cd-1-9], [`saturating_dist`][f-sd-1-9],
[`wrapping_dist`][f-wd-1-9], [`unwrapped_dist`][f-ud-1-9],
[`overflowing_dist`][f-od-1-9]
* The [`unsigned_dist`][f-unsd-1-9] method was added to all signed
fixed-point types and to the [`FixedSigned`][tfs-1-9] trait.
* The following associated types and provided methods were added to the
[`Fixed`][tf-1-9] trait:
* [`Signed`][tf-s-1-9], [`Unsigned`][tf-u-1-9]
* [`get_signed`][tf-gs-1-9], [`get_unsigned`][tf-gu-1-9]
* [`get_signed_mut`][tf-gsm-1-9], [`get_unsigned_mut`][tf-gum-1-9]
* The new trait [`FixedEquiv`][fe-1-9] was added.
* The following traits from the [*bytemuck* crate] were implemented for all
fixed-point numbers, added as supertraits to the [`Fixed`][tf-1-9] trait,
and implemented for the [`Wrapping`][w-1-9] and [`Unwrapped`][u-1-9]
wrappers ([issue 31]).
* [`Zeroable`][bm-z-1], [`Pod`][bm-p-1]
* [`TransparentWrapper`][bm-tw-1]
Compatibility notes
-------------------
* Now the [`Debug`] implementation for [`Wrapping`][w-1-9] outputs the value
only without “`Wrapping()`”, and the [`Debug`] implementation for
[`Unwrapped`][u-1-9] outputs the value only without “`Unwrapped()`”.
* The [`LeEqU8`][leu8-1-9], [`LeEqU16`][leu16-1-9], [`LeEqU32`][leu32-1-9],
[`LeEqU64`][leu64-1-9] and [`LeEqU128`][leu128-1-9] traits now have a
`'static` constraint. This should have no practical side effects, since
these traits are a convenience feature and already have the
[`Unsigned`][uns-1-9] marker trait as a supertrait, and the types that
implement [`Unsigned`][uns-1-9] are `'static`.
* The [`FixedOptionalFeatures`][fof-1-9] trait was not sealed, which was as an
oversight. Now it is sealed, and the documentation explicitly states that
the trait should not be used directly.

# Version 1.5.0 (2020-11-05)
* The [`wide_mul`][f-wm-1-5] method was added to all fixed-point numbers up to
64 bits wide ([issue 25]).
* Unwrapped methods for arithmetic together with the [`Unwrapped`][unw-1-5]
wrapper were added. Unwrapped methods panic on overflow, even when debug
assertions are disabled, similar to how wrapping methods will wrap around
even when debug assertions are enabled. (This was previously an experimental
feature `unwrapped`.)
* The [`serde-str`][feat-1-5] feature was added. (This was previously an
experimental feature.)
* For the experimental feature [`num-traits`][feat-exp-1-5], some missing
supertraits were added to [`FixedOptionalFeatures`][tfof-1-5].

# Version 1.4.0 (2020-10-22)
* The following methods were added to all fixed-point types, to the
[`Fixed`][tf-1-4] trait, and to the [`Wrapping`][w-1-4] wrapper:
* [`recip`][f-rec-1-4], [`checked_recip`][f-crec-1-4],
[`saturating_recip`][f-srec-1-4], [`wrapping_recip`][f-wrec-1-4],
[`overflowing_recip`][f-orec-1-4]
* For the experimental feature [`num-traits`][feat-exp-1-4], the following
traits were implemented where applicable ([issue 23]):
* [`Num`][nt-0-2-num]
* [`Signed`][nt-0-2-signed], [`Unsigned`][nt-0-2-unsigned]
* [`Inv`][nt-0-2-inv]
* [`MulAdd`][nt-0-2-ma], [`MulAddAssign`][nt-0-2-maa]
* [`FloatConst`][nt-0-2-fc]
* [`ToPrimitive`][nt-0-2-tp], [`FromPrimitive`][nt-0-2-fp]
* For the experimental feature [`serde-str`][feat-exp-1-4], serialization in
human-readable formats was made more convenient to write manually ([issue
24]). This makes it incompatible with the version in 1.3.0.

# Version 1.3.0 (2020-10-15)
* The [`MulAssign`] implementation on fixed-point numbers now accepts an rhs
fixed-point number with a different number of fractional bits from `self`.
* The following methods were added to all fixed-point types, to the
[`Fixed`][tf-1-3] trait, and to the [`Wrapping`][w-1-3] wrapper:
* [`mul_add`][f-ma-1-3], [`checked_mul_add`][f-cma-1-3],
[`saturating_mul_add`][f-sma-1-3], [`wrapping_mul_add`][f-wma-1-3],
[`overflowing_mul_add`][f-oma-1-3]
* The new experimental feature [`unwrapped`][feat-exp-1-3] was added,
providing arithmetic methods that panic on overflow even when debug
assertions are disabled.
* The new experimental feature [`serde-str`][feat-exp-1-3] was added, which
makes serialization use the number’s value in human-readable formats.
