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.
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.
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.
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.
TG-553
Replaced KEY_F7 and KEY_F8 with KEY_VOLUP and KEY_VOLDOWN.
Remapped the T-TWR Plus volume up and down keys to those, fixing a bug
in the pmu key detection where the wrong active edge was selected.
Adapt soft volume code for the UV3x0 to control code in the T-TWR Plus
by acting on the AT1846s Rx gain.
For target T-TWR Plus bound long press of KEY_VOLDOWN to macro menu open.
Unbound KNOB_LEFT and KNOB_RIGHT to squelch control and bound
instead KEY_VOLUP and KEY_VOLDOWN.
TG-553
A proper baseband reset is now issued at each startup. Now OpenRTX check
for SA868 responsiveness before proceeding with radio initialization,
eliminating unstable behaviour at boot.
TG-553
Enabled AT+TURBO command on SA868 that switches the baud rate of the
serial communication from 9600 to 115200 to get a more responsive
baseband. Bumped up the required baseband firmware version to
v1.1.0.r20.
TG-553
Modified keyboard mapping to enable macro menu, interface is still
broken as the T-TWR Plus is missing a keyboard.
Now the volume down key, mapped as the MONI button can be also used to
set the squelch level.
TG-553
Enabled Tx capability on T-TWR Plus.
Since Tx requires the SA8x8 to disable the Rx stage, we check that at
least firmware v.1.1.0.r14 is present on the baseband, otherwise we
don't initialize the radio.
