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...


What is the thought of putting two processors in parallel sharing all but one pin. And only one is active at a time depending on the state of the one pin at reset?

I have a system that needs to run for years. But is in a place where it cannot be maintained. The desire is to have two processors, one running, and one in backup. The second can be powered down, or powered up, but in lowest power sleep mode. If a pr...

IRQ from SPI DMA Rx Complete before end (too early)

I use an SPI interface with Rx and Tx DMA to transfer a 22 byte buffer from a spi slave. Chip select is handeled withLL_GPIO_ResetOutputPin(TDK_nCS_Port, TDK_nCS_Pin);set to high again to end transfer I wanted to use:// SPI5 - IMU TDK Rxvoid DMA2_Str...

1.board-NUCLEO-H743ZI2 . we are dumping code into flash externally through USB .for that we are making boot0 pin high and low it possible to make boot0 pin high and low in software. I don't have access to change boot0 pin in MX.

we are not able to change boot0 pin in MX configuration. for other input output pins we are able to change the configuration but not for boot0 pin.Thanks in advance.

Keyboard scanner library sought

I'm in search for a library of routines that allow for scanning keyboard matrices with or without diodes in various configurations. I've heard it exists for Arduiono but I'm pretty sure there is such for the STM32 series too (my target is an STM32F10...
