Dear all,I'm checking if a variable assignement is atomic or not. I know that are many stuff on this subject but I need to approach from a low level perspective to better know what happen under the scene and then have better control of my code.To do ...
I'm in doubt about the transconductance parameter of the HSE oscillator in STM32L443.To select an appropriate cristal I studied AN2867.If the datasheet of STM32L443 which notes "Gm = 1.5mA/V" refers to gm the transconductance of the passive elements ...
Hello,Am using STM32F407IGT6 in my design. I power the VDD, VDDA & VBAT from 3.3V.I use an external voltage reference using LM4121AIM5-ADJ which generates 3V from 3.3V input.When I use this external reference of 3V as VREF+, I would like to understan...
I am using STM32CubeMx to generate default files to build with Makefile. I edited the main.c to print some logs using printf. I am unable to see the same logs in the serial. Am I missing anything ?
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...
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...
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...
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...
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...
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...
