Posted on October 09, 2012 at 23:15Hi, I'm trying to connect together two USARTs. First is set as a transmitter and second as a receiver. I connect together two pins on the board PA9 - USART1_TX and PC7 USART6_RX. I have problem with receving data b...
Posted on October 11, 2012 at 09:48Good morning, i'm working with a stm32F0-Discovery board (cortex M0), i need to change the PWM pin from PA8 (using TIM1) to PC8 (using TIM3), but there is a problem because it works wrong.In the following codes i h...
Posted on December 02, 2011 at 06:03Hi everyone,I'm starting with the stm32f100rb and trying to set up the communication with 28j60(SPI). As far as know the 28j60 only support the spi mode 0 and run at frequencies of at least 8 MHz.To compile with...
Posted on October 11, 2012 at 09:31Hi everyone!I'm new to the world of microcontrollers. After some research, I bought my first ARM based Microcontroller; the STM32F4 Discovery.Now, I have a few questions for the community, hopefully someone can ans...
Posted on September 22, 2012 at 03:30I'm familiar with using alternate function inputs on the STM32F1 series; the associated GPIO pin is set as an input (CNFx[1:0], MODEx[1:0] bits), AFIO clock is enabled, and the AFIO->MAPR register is set appropri...
Posted on October 05, 2012 at 11:28Hello, Did some more tests on my TIM + DMA issue with also atollic to verify it was not the compiler. I am now pretty sure it is a hardware bug in the STM32F051. I tried almost every configuration possible, but if ...
