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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi， I'm using comp1 of stm32g474rbt6 and setting 70mV hysteresis.when a DC signal input PB1,the output always shake。But comp4 do not like this.
Hi there!I hope some one can help me. I use one STM32G031F4P6 for one my project, and i use the serial port with one RS485 ic, My problem is that i don't have any problem to receive the data from PC to micro controller the problem is the opposit re...
Hi All, I'm using an STM32F401CCU with a TI PCM5102A DAC. I've set up a simple DMA (code attached) and a naïve square wave function. My issue is that the generated square wave is at the 'wrong' frequency. In the code I am generating a 440 hz (or mult...

Digikey has some STM32 CPUs in stock, lets see how long that stock will last.
Hi I'm trying to generate a signal with 100 ns time on and 100 ns time off thanks to DMA transfer. My problem is that I have a peak of tension before and I don't know what is it (F446RE)Here is my code:int main (void) { /*Clock and Power initial...
I bought Nucleo-L4R5ZI.I can't find any document with HW information such as memory map, registers, etc. for Nucleo-L4R5ZI.I could find a document with HW layout and other information.Where can I find a document that contains HW information such as...
Iam new to stm32 microcontrollers, i have to read uart continuously and store to array. and size of the data received from uart is variable. if i use the fifo with uart i can solve problem.so please help me how program to receive data from uart in fi...
The reference manual (RM0440 Rev 7) has a point about WRP on page 125 regarding if the two banks are swapped. Why do the WRP2A_STRT and WRP2A_END registers have two different sets of values? It looks like one set is for Single Bank mode and the oth...
