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...
DS12288 (STM32G474) and DS12712 (STM32G473) Rev1 both have occurrences of "SDIO" in Table 13.
We are using STM32F722VET6 MCU in one of our project.Memory defined are in linker as below:RAM : 256KBROM : 512KBStack : 4KBWe have configured below peripherals and developed an application code using user defined functions. Which is working as exp...
I'd like to ask how the STM32F429 recognizes data reception in case of SPI while there is no any start bit? I know that there is RXNE bit in SPI_SR status register, but how SPI knows where is the first bit of the transmitted byte? Is it somehow sync...
HI everyone, i'm trying to do an a SPI communication between the board STM32F746 and the MAX7219 to controller a matrix. i'm working in keil uvision 5 and programming without libraries, DMA, CMSIS or other. i programm through registers putting '1'. i...
Dear Member,I'm confused between pointer and array,Please correct me :void sim7600_modem(char *SIM_TxBuffer){ printf("sim7600_modem ATI\r\n"); //Clear buffer HAL_UART_Transmit_IT(&huart1,(uint8_t*)&aTxBuffer4, sizeof(aTxBuffer4)); HAL_Delay(5...
Dear Members,I got a wrong data on I2C 2 for LCD, the first time it was ok, after a while it becomes like in the photo, what do you think the cause of it ?I have put a pull up resistor for it 10K, and the speed is 100KHz,I2C1 for Accelerometer and te...
HiTimekeeping in my application is pretty standard: 32 bit unsigned integers which store milliseconds since boot, overflowing every 49 days.To reduce power consumption, i need a way to wake up from stop mode at a set time in ms. But my device has nei...
Is there a document outlining how to power and test the crystal oscillator from ST? STM32F405
Hi, there, I am not sure this is the right place to ask if it's concerning IDE.Just got my new STM32H747 Discovery kit, running CubeMX examples,All running well, except for debugging:(I am using MDK Keil (V5.27 / V5.28) and on-board STLink V3)I found...
