1 year ago Just tested on mine, and it is reading correctly, so the target pin definition is correct..
Both current sensor and voltage are set to ADC. I did have to calibrate the current sensor scale, but closely tracks the current displayed in my power supply.
My current scale is set to 86, but you should try to calibrate to your needs. Matek's website sugesting using 150 for current scale and 2100 for voltage scale.

Current Behavior
No Current reading with ADC on Matek H743 wlite
Steps to Reproduce
Set to ADC -> current is 0 regardless of scale Set to ESC -> current gets displayed but with wrong Set to ADC -> current is 0 again
voltage sensing works
Expected behavior
Current gets displayed
Suggested solution(s)
Maybe PIN declaration for ADC is off. Manual says current sense is PIN 11
target.h:
define ADC_CHANNEL_1_PIN PC0 //ADC123 VBAT1
define ADC_CHANNEL_2_PIN PC1 //ADC123 CURR1
define ADC_CHANNEL_3_PIN PC5 //ADC12 RSSI
define ADC_CHANNEL_4_PIN PC4 //ADC12 AirS
define ADC_CHANNEL_5_PIN PA4 //ADC12 VB2
define ADC_CHANNEL_6_PIN PA7 //ADC12 CU2
