May I ask if it's possible not to use FlyskyHallStick? Replace with the original potentiometer

"The code includes an automatic detection of FlySky digital hall gimbals on power-up of TX16S/T16/T18 radios and no special build-time option is required. If after initial 70 ms the FlySky gimbals are not detected, the code reverts to sampling analog sticks."
What is the GPIO corresponding to the analog joystick? Where exactly is the code set?

Try read the CMakelists.txt in targets, you need to have this line to enable Flysky Gimbal detection:

Thank you, but I would like to know what is the default GPIO for the analog joystick?

[richardclli]

The GPIO is radio specific, check out the definitions in hal.h

Thank you very much

There is also more information on the Flysky Hall Sticks mod here => https://github.com/EdgeTX/edgetx/wiki/Flysky-Hall-Sticks-Mod

This should explain how to use Flysky Hall Sticks, but I don't want to use it

Ah, sorry, I thought you were after the GPIOs for the hall sticks, which is actually mentioned somewhat obliquely on that page for some TXs... i.e. UART4 TX and RX, which equates to PA0/PA1. In that case, you're after this =>

edgetx/radio/src/targets/horus/hal.h

Lines 291 to 294 in 0506841

	#define ADC_GPIO_PIN_STICK_LH LL_GPIO_PIN_0 // PA.00
	#define ADC_GPIO_PIN_STICK_LV LL_GPIO_PIN_1 // PA.01
	#define ADC_GPIO_PIN_STICK_RV LL_GPIO_PIN_3 // PA.03
	#define ADC_GPIO_PIN_STICK_RH LL_GPIO_PIN_2 // PA.02

Unless you're not asking about a X10 family transmitter, as you never mentioned what transmitter this is in relation to ;)

Thank you very much
