Hello,I would like to use TWO circular DMA buffers for ONE I2C interface.Depending on received address byte, in the ADDR interrupt I would always enable the correct circular buffer (disabling the other one - so at one time always only ONE buffer is a...
Hi, I am trying to use an STM32G031J6-DISCO board to get a grasp on the 8-pin STM32G031J6 MCU that I consider for building small IoT sensors (for teaching purposes). I am new to STM32 products (or ST MCUs in general). I managed to write a few variati...
SPI receive funtion not working correctly. Only one time is working, where is my mistake ?thanks void SPITransReceive(SPI_TypeDef* SPIx,uint8_t data,uint8_t *pbuff,uint8_t dataSize){ while(dataSize > 0){ while((SPIx->SR & SPI_I2S_FLAG_TXE) == R...
How do I measure the time between the rising edge and falling edge of a square wave
Hello,I am working with ADS7046 i need to generate 24 cloacks for calibarration and for data I need the 15 SCLK .Its SPI COnfigurable. So how I can genertare the 24 SCLK and 15 SCLk
I have a few boards using an STM32L4 part.Some of the boards are working as expected, but others are not. The ones that don't work reach a timeout in the SystemClock_Config() function call. Specifically, they time out in the while loop at line 558 of...
