Cannot use PA6 as analog input with a NUCLEO-H743ZI2

[pierremolinaro]

• OS: Mac OS X
• Arduino IDE version: 1.8.13
• STM32 core version: 1.9.0
• Board Name: NUCLEO-H743ZI2

Describe the bug
I try to use PA6 as analog input. Calling analogRead (PA6) returns always zero.

Bug Fix
I think the bug is in the ~/Library/Arduino15/packages/STM32/hardware/stm32/1.9.0/variants/NUCLEO_H743ZI/PeripheralPins.c file.

Line 57 {PA_6, ADC1, STM_PIN_DATA_EXT(STM_MODE_ANALOG, GPIO_NOPULL, 0, 3, 0)}, // ADC1_INP3 is commented.

Uncommenting this line solves the bug.

Best regards,

Hi @pierremolinaro

In this case this is not a bug. The variant has been described like this.
Anyway with #1091 this will be changed as all pins would be available.

Ok, thank you very much for your answer.
