Posted on July 10, 2013 at 17:17 I'm not sure how to remap pins that do not line up correctly with the alternate functions specified in the datasheet. For example, the picture below shows the pin out of my microcontroller where OCx-LOW are pwm o...
Posted on July 13, 2016 at 14:08 Hello, I am working with the boardNucleo-L476RG and I wantto capture frequency on the pin PA0 with TIM2 Channel1. My timer is working but I can't get the interrupt in the function TIM2_IRQHandler(). I a...

Posted on July 15, 2016 at 02:51Hi,I configured USART1 to PA9/10. And I want to use PB6/7 to GPIO.First I initial the USART1 function(using PA9/10), and works well(putchar works well). But when I initial PB6/7 to GPIO by GPIO_Init() function, USART1...
Posted on July 12, 2016 at 15:17Hello, I'm new to Stm32 programming, but I try hard. I'm at the bottom of the earning curve and I block since 2 days on the an issue issue. Help would be very much welcomed. I attach my project:https://dl.dropboxuserc...
Posted on July 11, 2016 at 09:53Why does Nucleo 64 not have the sound ouput module I2S DAC as extenstion board?Nucleo 64 is really comfortable for audio eval project. Why didn't ST add the I2S extension eval board?ST added some code for I2S DAC but ...
Posted on July 12, 2016 at 05:18 Hello, Here is my code static void SPI_EnableMaster(SPI_TypeDef *SPIx, uint16_t SPI_CLOCKDIV, uint16_t SPI_MODE, uint16_t SPI_DATA_SIZE, uint16_t SPI_LSBFIRST) { SPI_DATA_SIZE--; SPIx->CR2 = (...
Posted on November 06, 2015 at 16:44Hello, WWDG should be used in my application, some safety operations should be done in the EWI, I found some bugs in the firmware library, which will be discussed here to help other developers.Experiment set-ups:I...
Posted on July 15, 2016 at 15:26I just used the USBD_MSC sample from the cube with the F7 Discovery board and configured the HS core to run FS speed only (our own hardware will have no ULPI), therefore changed usbd.conf.c, line 382: hpcd.Init.spee...
