Posted on April 28, 2015 at 16:49Hello I am using the STM32F4 interfaced with two hall effect quadrature encoders.Is there a method to generate the signals (A,B) coming from the encoder to validate my work ? because now i don't have the sensor #...
Posted on April 29, 2015 at 14:24I bought a discovery board with STM32F4 family processor (comes with a TFT LCD). I have my IDE working and downloaded CubeMX and generated some init code - no problem.Now, I don't know how to do anything! How do I to...
Posted on April 29, 2015 at 10:46Hi,I have a doubt concerning the clock architecture of the MCU in subject.Can the System Clock be used directly for any master (CPU core, DMA etc.) without passing through the AHBx prescaler. The reason for this ques...
Posted on April 26, 2015 at 11:42 Guys, I have generated a code for Keil from CubeMx but I can't initialize GPIO, I can see a code in main.c below....anyone knows how to initialize GPIO,reset and set a bit on it at CubeMx generated c...
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...
