New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...


STM32: Performance for FFTs

Resolved! Currently we make use of three SPI busses on a STM32F405. SPI1 is a slave and SPI 2/3 are masters. I switch SPI1 to master mode and it just doesn't work. I suspect the APB2 bus but I think I have it set correctly.

Here's my code:SPI_HandleTypeDef spi_handle = { .Instance = DEF_SPI_INS_SPI1, .Init = { .Direction = SPI_DIRECTION_2LINES, .BaudRatePrescaler = SPI_BAUDRATEPRESCALER_2, .CLKPh...

I'm running tx and rx of SAI_I2S by double buffered DMA.I expect on double buffered DMA to change Current Target or CT register bit state to change at each Transfer Complete or TC. But on tx DMA stream it changes CT, one sample before TC. Why? But in...
