I was reading the documentation from: https://www.st.com/en/embedded-software/x-cube-eeprom.html#documentationabout the eeprom lib. Concerning the cleanup time, I don't follow where the number comes from. I am using an L4 and there was only one examp...
Hi I come across an ADC code as below, could anyone advise whats the meaning of pointer *h in the function argument and whats (h = &hadc1) do inside the callback function ?main(void){ HAL_ADC_Start_IT(&hadc1); ... while (1) { if (adc_valid ...
Dear Experts,I have 4 inch RPI LCD 480x320 SPI based on the ILI9486 display driver. Like inside ArduinoIDE, there is a Library manager where we can find so many TFT-LCD libraries with STM32 board support, Is there a common place to find libraries for...
how does fmc work does it use spi?
Is the maximum APB frequency setting 36MHz or 50MHz? See the dm00031020, page 863. FREQ[5:0]: Peripheral clock frequency..."Higher than 0b100100: Not allowed"0b100100 corresponds to 36MHz, not 50MHz. Hopefully this is just a document error. We are us...
Hello,I am developing a serial communication driver using USART.I have enabled FIFO and RTO interrupt, to handle reception.TRM says that the received data is stored in the RXFIFO together with the corresponding flags and that PE, FE, NE bits in ISR r...
Hello,I am using a NUCLEO-H743ZI2 and program on the STM32CubeIDE1.13.2The purpose of my project is to create a 2kHz sine and to sample it at 40kHz at the same time.I would like to have no delay between the 12bits DAC and the 12bits ADC: that the fir...

Hello everyone, I'm working on an STM32H755BI (industrial temperature range), and i'm quite disappointed by the maximum clock reachable from the system.As can be seen, the MCU can reach up to 480MHz in the core M7 and 240MHz in the core M4.After mont...
