Posted on March 17, 2014 at 20:36Hello everyone,I am trying to make U-boot work on my STM32F4-discovery board, and I downloaded the Emcraft version which supports the STM32F429-Disco board. I have made the required modifications (I hope) but I am fa...
Posted on March 18, 2014 at 16:35 Hello all, I’ve been fighting for 2 days with a STM32F4-Discovery board to get the Timer 3 counting properly in External Counting Mode 2 but I can’t figure out what’s wrong in my code or in the MCU config. ...
Posted on January 03, 2012 at 17:08Hi All, I starting to use the STM32 with lwIP stack and I will need to use the multicast. Is there any example or demo for this ??? Thank you in advance. With Best Regards #stm32-+-lwip-+-multicast
Posted on March 18, 2014 at 13:32Problem: ST-Link utility can't connect the target MC.First of all I connected all the wires as necessarySWCLK-PA14, SWDIO-PA13, GNDand checked the quality of connections. Everything is OK.my program just configures P...
Posted on March 18, 2014 at 15:48HiI'm trying to read data from camera ov7670 with FIFO (AL422) with a stm32f4 micro controller. can I do this without using DCMI interface?if yes how can I do this? and is it necessary to use DMA?thanks #connecti...
Posted on March 17, 2014 at 15:01Hi, since some days I'm trying to create a code to operate the ADC with DMA for STM32F4 card, the problem is that my code does not work if I want to add a second chanel because it always displays the same values for ...
