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...

STM32L475 Setting the RTC to 24 hour mode

I am using a STM32L475 and plan to also use an STM32L451 processor, I am having trouble setting the RTC so that its in 24 hour mode. According to the datasheet setting a 0 to bit 22 of RTC_TR should set it into 24 hour mode but this does not seem to ...

The procss of using SPI slave with dma

Hi I am fairly new to SPI slave with dma on a microcontroller, I am wondering in firmware what is the process of implementing it? I have set spi1 up as spi slave and assign dma streams to it in the cubeide, but now that it is set up, how is the data ...

This is Horrible experance! It's taken me an hour just to get this far. I can't find anyone to call on this question. The number they have for support is out of service, and any atempt to find a number to call just sends back to the number.

If anyone has a working support number would be a big help.  My Question is on the STM32F411 the data sheets state many of the lines are FT 5 volt t​olerant, other team members don't believe this and want to use level shifters, they believe as many l...

Connecting 2 16-bit SDRAM as one 32-bit SDRAM

Simple question: is this possible without additional HW logic? I have these two 16-bit SDRAMs and I'd hate to use just one of them or to use them as measly two 16-bit SDRAMs. I think I've browsed through all 3200+pages of reference manual and couldn'...
