STM32F4Cube HAL_SPI_TransmitReceive_IT()

Posted on June 19, 2014 at 21:42Hello, I am interfacing an STM32F407 (on DISCOVERY eval) to several devices using SPI bus.  One of the devices clocks 4 bytes of data out simultaneously as 4 bytes of config data is clocked in (LTC2446 ADC).  I am att...

DMA reads from USART1 without RXNE set

Posted on May 06, 2014 at 12:11Hi community, I use the USART1 in STM32F100C4 to receive serial data in DMA mode. Because the data comes in packets with less than 16 bytes I start the DMA mode every time, when new data is expected. This works most of...
