Posted on April 29, 2015 at 02:34Hi all, I'm having some trouble reading more than one byte off the USART port I've configured. I'm implementing a polling receiver, as follows: char *end_obuf = obuf+len; char *start_obuf = obuf; int delay_coun...
Posted on April 01, 2015 at 19:10Hi, I posted a question yesterday which was solved by myself about the external mode connection. But now I am getting another problem, a timeout error. I am using the ''Embedded Coder Support Package for STMicroelect...
Posted on April 28, 2015 at 14:51Guys, Is GPIOE related with ETH on STM32F107 ? I tried to activate ETH and I can't send command to GPIOE ?? Are the multiplexed together ? Any clues ? thanks #i-have-a-clue
Posted on April 28, 2014 at 08:07Hi,I developed my project with stm32F0discovery and is OK. Now, I load my project to our board (final product) and I have a problem with timers and systick. For example: tim14 is set to operate 1 msec, instead I see ...
Posted on April 28, 2015 at 20:37We are using the same SDRAM on our board as stm32f429i-disco and my question is about the example code - STM32F429I-Discovery/Examples/FMC/FMC_SDRAM/Src/main.c where the initialization is only for BANK2, please confi...
Posted on April 26, 2015 at 22:50 Hi, I have problem with encoder mode. AS5040 is in quadrature output. I use this code and it doesnt work, where is the problem? void gpio_conf(void) { GPIO_InitTypeDef GPIO_InitStructure; RCC_APB2Peri...
