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...
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...
hey thereI have a STM32f030k6t6 which I wish to store data in its FLASH eeprom.the thing is sometimes data on certain addresses are cleared in startup! here is my codeHAL_FLASH_Unlock(); EE_Init();//eeprom initiallization EE_ReadVariable(ID_FLASH_ADD...
