Posted on May 04, 2016 at 22:50hi im working on a project to drive a WS2812B led string. i use TIM1 as time source and TIM3 for the PWM generation. im so far able to achieve a PWM signal @ 800kHz. For testing, i tried (see stm32f1xx_it.c) to drive ...
Posted on November 15, 2013 at 16:01The native CAN bootloader of STM32F107, revision Z, date code 244, produces many faulty messages. Peak CAN controller to communicate with the bootloader via CAN reports various errors as RX frame, TX frame errors,...
Posted on May 04, 2016 at 01:53Hello:I have develop a board where may install STM32F407, STM32F405 or STM32F427. Board is always same, and work perfect with F405 and F407 about the BOOT option to upload firmware by DFU USB.But when I install an F427...
Posted on May 06, 2016 at 12:54HelloI have upgraded from STM32Cube FW_F4 V1.10.0 to V1.11.0 and the SPI part doesn't work well. When sending only one byte at a very low speed with softwase NSS, the HAL_SPI_TransmitReceive() function will return befo...
Posted on December 02, 2014 at 14:14 Hello, anyone help me! Iwant to generate a dfu file for my STM32L053C8-Discovery bord, but whatever I fill in the blanks in the DFU File Manager, when I choose a hex file generrated by my Keil 5, an error occurs ...
Posted on May 05, 2016 at 12:37Hey guys, my first step in creating a bootloader was simply to move the app (which resided at 0x8000000 to 0x8020000 through the linker file. Next, I created a basic bootloader at address 0x8000000 which basically does...
Posted on August 05, 2015 at 17:25We used the DFUSE over USB successfully with several L152 designs. The L152 chips don t have a USB boot loader DFU like described in the AN2606 STM32 microcontroller system memory boot mode. (DFU SE via USB) So we d...
Posted on May 04, 2016 at 09:03 Dear Experts! I've tested stsw-stm32026 demo code and that worked perfect. Next I wrote simple SPI flash driver, and tried to load server files from this flash instead of stm32f107's internal flash. i...
Posted on May 02, 2016 at 11:11Hi everyone, I would like to include in my project FreeRTOS a uart queue. I have already done this with the StdPeriph lib but I'm facing difficulties to migrate from StdPriph to HAL. My previous project was build l...
Posted on May 02, 2016 at 19:33I am getting started in developing for the STM32F407.One thing that is certain is that I will need either secure read/write (i.e. passcode-protected), or encrypted read/write (i.e. data read out not immediately readibl...
