I am using multiple channel and multiple ADC's and I am trying to use the Interrupt method ,My first doubt was lets say we are using End Of Sequence Conversion flag So, the interrupt will be triggered when all conversion will be complete then how we ...

Resolved! Timer 16 bits is less stable than Timer 32 bits in PWM input mode

Hello everyone,I read PWM input value by Timer 16 bits in Nucleo-F767ZI (combined channel mode), but the value that I received is not the same after some days.For example, Day 1: PWM input value = 4200 but Day 4: PWM input value = 4000, no code chang...

Hi,I know the question has been asked before, and there is some information (to some extent) on the internet, though I cannot seem to make it happen. My question is:How can I use print() for debugging purpose? I have an UART peripheral up and running...

STM32U599 QSPI connect PSRAM, MR read/write OK, but write/read data from PSRAM fail

Using STM32U599 Hex SPI connect with PSRAM(256MBits， 32 MBytes), configure Hex SPI as QSPI, command/address is 4 Lines and 32 Bits. Only use IO0/1/2/3 and CS/CLK and IO15(used to make PSRAM enter OSPI or QSPI mode)Now, we could read/write PSRAM Mode ...
