Posted on September 06, 2015 at 11:09 Hi everyone. Few days ago I realized that my NVIC priorities don't work. I'm tring to use three different interrupts by timer, exti and SysTick. I guess when EXTI or SysTick have highest priority then TIM...
Posted on September 04, 2015 at 17:17Hi, Based on the STM32L4 datasheet the maximum QSPI clock is 48MHZ, but the clock used for the cube examples is 80MHZ. should I reduce the clock to 40MHZ? I'm using the Spansion S25FL127S memory in my custom boar...
Posted on August 24, 2015 at 11:15Hello, Can anybody help in order to setup the USART1 on this controller? I have a ST NUCLEO dev. board with this Microcontroller. I don't want to use the Cube generator. I want to use the stdperiph driver without ha...
Posted on September 17, 2014 at 01:59Hello, all. I am looking for the firmware examples for AN4507 (PWM resolution enhancement through dithering technique for STM32 advanced-configuration, general-purpose and lite timers). The document mentions STS...
Posted on September 07, 2015 at 11:40Good day,I have tried to use new discovery f7 board with camera.It works fine, for now I am writing uncompressed video to avi file in microsd card.I wanted to ask which codec to use for video compression, like xv...
Posted on September 03, 2015 at 09:23 Hello, We're using an STM32F103RD for one of our product and on which an extrenal crystal (768Khz) is connected on OSC32 In and ON (LSE). My problem is that this crystal only start to oscilla...
Posted on August 14, 2015 at 15:22Hello,is there a way to make 3 synchronous PWM outputs of 100kHzthat each of output would generate particular amount of pulses and then stop?I saw: https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm3...
Posted on September 06, 2015 at 15:07I want to create a new project that use USB device CDC library using System Workbench and not CubeMX. I make a new AC6 project, select my F4discovery board, and check USB Device Library and HAL firmware library. ...
Posted on September 04, 2015 at 18:20Dears,I've got Core107V board from Waveshare with STM32F107VCT6 (rev.Z) and I want to flash my program using USART1.I've plugged FTDI converter the board according to the information in datasheet.3.3V => 3.3V on ...
Posted on June 22, 2015 at 22:59Hi.So I'm having a peculiar problem with the SPI on the STM32F072.I'm trying to configure SPI1 and it seems to work, but with one cave-eat. I can't seem to configure the bit size (SCLK) down to 8b from 16b. I've been ...
