Hello,on an stm32f429,I trigger an interrupt on PA0 for 1 second andI light an LED on PA3 for a short time, with a timerI count the number of overflows on a 10 Mhz signal onPA5 and store the result in a variable,I'm a beginner with STM32F and I must...
I've been attempting to stream audio in via a USB microphone using the USB host functionality on my STM32F411. Unfortunately, it seems as though the audio class has been left unfinished and, although about 50% of the code is there, the other importa...
Hi, I'm creating Boot sw & App sw in one board. which means, 2 independent STM32 Proj. runs in same Flash / RAM. There is an issue when HAL_RCC_GetSysClockFreq() has been called. The first called sw, boot sw, doesn't make any trouble. but the second ...
