Resolved! Use GPIO Analog for ADC read value on STM32H735
Hello, Is it possible to configure PA10 on STM32H735 as GPIO Analog and use it to read ADC Value ? The AN4899, 4.3.4 Analog Configuration says : Few STM32 GPIO pins can be configured in analog mode which allows the use of ADC, DAC, OPAMP, and COMP in...
Private read of I3C target
hello:I have a question about I3C private read when I use STM32H563 as a target.Usually, the number of bytes returned by the target can be set through LL_I3C_ConfigTxPreload, but if the target is uncertain about how many bytes to return, that is, th...
