STM32F407 - Flag RXNE of SPI is clear when i read. Sometimes is stack in waiting the flag.

Hi, i using SPI for communicating Transmiting and Receiving with STM32F407. My routine for transmit: void spi_transmit(uint8_t DataX) { //Envio while(!(SPI_TFT->SR & SPI_SR_TXE)); SPI_TFT->DR = DataX;...

event flag

what are the definitions of each event flag bits
event flag

what are the definitions of each event flag bits
RTX flags etc

In the Keil help section it seems to imply that each task name gets its own individual 16bit flag ie. as in os_evt_set (0x0004, id2); and os_evt_set (0x0004, id3); if so, how does os_evt_wait_or (0x0004...
