Error in linker script definitions made the heap area to start at end of the
64kB CCM RAM, thus effectively allocating memory in an access-protected zone.
Module17 uses an OLED display, which does not have contrast regulation. The
contrast control register, however, allows to change the brightness of the
display.
Reorganized code for pixel framebuffer in order to have it instantiated once
and for all the possible display drivers. Dropped the display_getFrameBuffer()
function.
Using the newlib's printing functions without floating point support in order
to reduce the overall binary size. This allows to free up around 15kB of space
in the .text section.
Switched to int32_t for RSSI representation to allow running the code also
on devices with limited resources. Defined a new ad-hoc type to still keep
the possibility of using floating points on more capable devices.
General code optimization allowing to reduce the overall binary size, especially
for devices without hardware floating point support. On the MD-380 (which has the
FPU) the .text size has been reduced of 4'928 bytes.
The "revisions since last tag" version field is now accurately named and no longer checked. Extra parentheses also added to reduce compiler warnings.
Fix#217
Removed an old workaround for an hardware bug of Module17 rev 0.1b limiting
the output swing of baseband signal in newer hardware revisions.
Contribution by Mathis Schmieder DB9MAT.
Declared the "mod17CalData" variable inside linux platform.c to make the symbol available
to the linker when building the linux emulator with the Module17 UI.
Fixed error in compuation of values for AT1846S frequency registers
causing the output frequency to have an effective resolution of 1kHz
instead of 62.5Hz.
T-TWR Plus target now produces images in UF2 format.
This format is compatible with bootloaders such as tinyuf2, and future
releases of the hardware will come pre-flashed with tinyuf2, thus
flashing them will not requires any other dependency than the uf2 file
itself.

Enabled 10 second long press emergency shutdown PMU function to be able
to reset the radio even when OpenRTX is freezed, without the need of
pulling out and back in the battery.
TG-553
On LILYGO T-TWR Plus the squelch was being controlled by AT1846s,
resulting in the squelch bar setting being completely ignored. Now we
are introducing the support for a new command of sa8x8-fw called
AT+AUDIO that controls the muting or unmuting of the speaker power
amplifier, enabling us to:
1. Disable AT1846s embedded squelch
2. Enable OpeRTX squelch
Also fixed a bug where the sa8x8-fw version was incorrectly checked.
AT+AUDIO requires sa8x8-fw version v1.3.0.r1, bumped version check in
OpenRTX.
