__WFI works beauty. But I want more. Behold:void vApplicationIdleHook() { __WFI(); my_own_code(); // on wake, this will be executed *after* the intr handler :( }Upon every wake from WFI, I want to execute my own code immediately: ie. bef...
I hope this question is not off topic.I have a board running httpd using a STM32F407. The web server is running CGI and SSI. The cgi file is named index.shtml and is called when the browser first accesses the website.In the SSI part of the code I pop...
Hello!I am trying to use the NOR flash module on the STM32L4R9I-EVAl board. I've been able to use the ST-provided example without issue, but in trying to build a project through CubeIDE, I've run into an intermittent fault. Sporadically, my writes to...
I'm getting a lot of noise from my STM32 design, which is just supposed to be direct line-in/out I2S with DMA.I'm feeding in a 440Hz sine wave to my CS5343 A/D converter:And this is the output I'm seeing from my CS4344 D/A converter:If I zoom out a b...
Hi, i have some rather strange problems with my custom with an STM32F103C8 mcu on it. It is programmed via an Nucleo ST Link v2/1 and it works fine most of the time. I can load some test sketches on it via Platform IO or STM32CubeIde. But after a fe...
Hi, anyone know there is a register that can count the pulse directly on STM32H7?I know there is a timer in capture mode, it can generate interrupt when detected edge high or low. But this counter does count the period time only, does not count how m...

Im trying to write to and read data from 10 eeproms in parallel. I first transmit the data in parallel to all the eeproms via spi, I then read data in parallel by first transmitting the address of data stored in the eeprom and then transmitting dummy...
I know its clock is provided from the APB1, but I can't figure out how to calculate and what are the relations between fdcan_ker_ck and fdcan_pclk
