Resolved! HSE fails to initialize in STM32F205ZG using SPL
hello! I was devolving my project on the "STM3220xG eval-board" (based on controller "STM32F207IGH6"). Now as my custom made controller board is ready (based on "STM32F205ZGT6"), I ported my code for it by changing in peripheral's Pin-numbers and Ke...
How to calculate the prescaler of TIM?
Posted on September 28, 2017 at 06:50HI.Now I'm trying to implement TIM into the STM32F429i-DISCO kit.But I need to help how to calculate the prescaler and period value for user?As I know currently I used 180Mhz as system clock. and I want to set TI...
Android USB HID driver for STM32F1 Series
Hello there. I am trying to implement a USB HID driver for the STM32F1 series. I tried several generic examples of Android USB HID drivers on the web, but none of them seem to work with what we have. I was wondering, how would I approach implement...
How to debug properly UART interrupts?
My UART works well in normal mode, but when I want to analyze callbacks for Rx in debug mode it doesn't work properly. I mean when I set breakpoint at HAL_UART_RxCpltCallback and I'will send bytes from terminal, debugger stops at this callback and do...
HAL_SPI_Transmit() Size, is it defined as a byte or a word?
Hello,I have a very simple code. A two byte array that I need to send over SPI.uint8_t my_array[2]; my_array[0] = 0x10; my_array[1] = 0x01; HAL_SPI_Transmit(&hspi1, my_array, 2, SPI_TIME_OUT); // or HAL_SPI_Transmit(&hspi1, my_array, 1, SPI_TIME_O...
STM32L476 CAN Bootloader
Hi,we want to use the built-in CAN bootloader of a STM32L476. We experienced some strange behaviour while testing with a nucleo board, which we could partly fix.First of all, after a write command, sometimes two ACK are sent, the data is also written...
Using nucleo board as offline programmer
Hi,i'm wondering if there is an easy solution for using nucle board as field programmer over SWD interface. I would like to programm blank stm32 device directly from nucleo board using external flash or stm32 device content. It should be done over on...

DCMI to QSPI storage
Hi there,I am trying to use DCMI on STM32F469. Due to the limitation of the internal RAM, external RAM is needed. One option is to incorporate a QSPI-PSRAM. After reading "AN5020 - Digital camera interface for MCUs", my question still remains: Can DC...
