I've been annoyed at the calibration of the t8sg plus with hall effect gimbals. I can't seem to hit all 4 corners of each at max input after calibration. So I was thinking of doing a 2d stick calibration. Basically get all 4 corners (probably the center point of each stick as well). Then calculate the stick positions based off of that data.
Something like this in _tx_configure.c after the other calibration (Just some quick code)
s32 horz;
s32 vert;
//loop through each stick
for (u8 i = 0; i < 2; i++) {
if (i = 0) {
horz = CHAN_ReadRawInput(INP_RUDDER);
vert = CHAN_ReadRawInput(INP_THROTTLE);
} else {
horz = CHAN_ReadRawInput(INP_ELEVATOR);
vert = CHAN_ReadRawInput(INP_AILERON);
}
if ((horz < Transmitter.fullstickcalibration[i].bottomleft[0]) &&
(vert < Transmitter.fullstickcalibration[i].bottomleft[1])) {
Transmitter.fullstickcalibration[i].bottomleft[0] = horz;
Transmitter.fullstickcalibration[i].bottomleft[1] = vert;
}
if ((horz > Transmitter.fullstickcalibration[i].bottomright[0]) &&
(vert < Transmitter.fullstickcalibration[i].bottomright[1])) {
Transmitter.fullstickcalibration[i].bottomright[0] = horz;
Transmitter.fullstickcalibration[i].bottomright[1] = vert;
}
if ((horz < Transmitter.fullstickcalibration[i].topleft[0]) &&
(vert > Transmitter.fullstickcalibration[i].topleft[1])) {
Transmitter.fullstickcalibration[i].topleft[0] = horz;
Transmitter.fullstickcalibration[i].topleft[1] = vert;
}
if ((horz > Transmitter.fullstickcalibration[i].topright[0]) &&
(vert > Transmitter.fullstickcalibration[i].topright[1])) {
Transmitter.fullstickcalibration[i].topright[0] = horz;
Transmitter.fullstickcalibration[i].topright[1] = vert;
}
}
Any gotchas there? Mode1 vs Mode2 controls?
