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...
I've managed to get the DFSDM working with a PDM microphone (on a STM32L496 board) - using direct access to registers. But the documentation often made things more difficult than they needed to be. Just a few extra sentences, less ambiguous language ...
Hello,I wanted to experience data transmission through NB-IoT in Canada by using a Cellular Discovery Kit (B-L462E-CELL1).The eSIM is activated and the board communicates with echoclient, but it selects the operator automatically. Unfortunately, the ...
As shown in above figure.The EXT/GPIO pin directly connected to MCU with pull up resistor (10K).So once the switch press the PMOSFET start switching supply to MCU.Please let me know the effect of voltage on EXT/GPIO pin without suppling power to MCU.
Hello.Hi Forum. I am new to the H743 line of processors and the first thing I tried is getting printf() output on the traceswo pin of my nucleo-H743ZI. What I have tried:1. The 'Everything out of the box' way:Use cubeMX to configure sys to async trac...
Hi everyone!I've got something strange with my ADCs (working on STM32H743). Everything was working until I realized that both of my ADC values are refreshed only if use other DMA peripheral. For example, it seems that sending SPI refresh the ADC, oth...
We develops the system that based on STM32H757 processorIn the working the application , I would compline to the three different running modes. 1. M7 - 480Mhz / M4 240Mhz --> full power mode (50% of application)2. M7 - 400MHz/ M4 200MHz --> run mode ...
I am using a Nucleo 303RE discovery board to try the SPI interface setting with STM CUBEMX, the setting is as below:SPI peed set: 4M/sSPI mode: 3Use HAL_SPI_Transmit API to send dataProblem: the SCLK clock shape is strange. The clock always has some...
