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...
A follow-up to this thread - for stm32L433 (Cortex-M4F):https://community.st.com/s/question/0D53W000014wcE5SAI/how-to-get-segger-rtt-to-work-with-sleep-modes-on-stm32Like that thread, I already have DBG_SLEEP, DBG_STOP, and DBG_STANDBY set - but the ...
I have tried to setup a minimal project where I configure the P-NUCLEO-WB55 board to trigger an interrupt (falling edge) when I press a button, that will toggle the blue LED (L1). I tried buttons SW1, SW2, SW3, all have the same problem: when I press...
Posted on October 25, 2017 at 11:53Hi all,I am using STM32L433, and checked the manual that it supports rx timout for the uart. I am using cubeMX v4.22.1 with Cube L4 firmware Package v1.9.0. I try to receive unknown sized data from UART3 but i do n...
In order to make the printf function accessible from other libraries, I create a retarget library where I call stdio and write my own implementation of _write function using UART peripheral. So when I want to use printf in another library. I add incl...
I'm trying to use RTT on an stm32L433 and it looks like it doesn't work when the device is in sleep mode (no output on the RTTViewer).my test code is a loop with a printf and a 2seconds sleep.when a debugger is attached, stepping through the code mak...
I am developing a fuel dispenser and it consists of five boards and the main control of the dispenser is CPU board and the fuel dispensing pulses comes from PULSER board and all the data input comes from KEYPAD board. All the boards are maintained a...
How fast is DMA on STM32H7 mcus? I didnt find any description on how many ticks takes one transaction. I linked DMA to a timer, transfer from memory to port. With system clock 480 MHz and timer DMA request frequency 40 MHz it doesnt seem to work fast...
I'm trying to use the idle line interrupt in combination with dma to send and receive data from the serial port to my STM32F417VG based board.I got as far as being able to send with dma successfuly and also reveive data via the idle line interrupt. T...
