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...
We are trying to send serial data from an ST microcontroller to a PC using CDC_Transmit_FS.We can send data less than 16Kbyte (4096 * 4byte) without any problem, but when we try to send larger size, sometimes we get USBD_STATUS_CANCELED (confirmed by...
I am trying to receive CAN FD and save the data to the SD card, but I am having a problem . Create and deliver an event structure in HAL_FDCAN_RXFifo0Callback, Receive the structure from the application area and call HAL_FDCAN_GetRxmessage. In this c...
I'm struggling with how to use the timers to achieve certain behavior and am looking for some advice. First I'll describe the purpose, then how I tried to approach it, and then why I'm stuck.I need a 32-bit timebase that counts up at exactly 48kHz an...
I am working on STM32L476RG MCU for this one i want to calculate CRC of flash memory. for this i uses 3 logics but my calculated CRC of flash memory is not matched with hex file CRC of code.i share the link here using which i calculate CRC of flash m...
Hi,I am working on two STM32 microcontrollers communicating over UART with baud rate 9600. The functional requirement states that I need to transmit and receive data at both microcontrollers. Currently this is not happening as the transmit and receiv...
I measure 9 channels (3 per ADC) with 12-bit resolution using DMA. The sampling time is set to 6.5 cycles, but the same issue occurred at 2.5 cycles. I get no results at all in the range from 2037 (7F5) to 2047 (7FF), but significantly more resul...
Hello everyone, I am using a custom board with STM32H750 and I am trying to develop a file system with FILEX. The file system' s media is a uSD card with 10 MB/s baudrate which is communicating with the micro thanks to the SDMMC peripheral. The SDMMC...
I am supposed to be receiving 8-bit data with even parity. The blocks are defined with a header of 'F0', this is S.Bus data if anyone knows that that is. I setup a simple program that just does receive data. I get data but nowhere does it show an ...
Hi, I am trying to stream ADC data to ethernet RJ45 port along with synchronized timestamps. Currently I am trying to figure out the following problems: 1. How can we synchronize ADC data with timestamps? The STM32 tutorial uses DMA, which I assume d...
Hello ,I am working with stm32h747. M4 .ld File FLASH (rx) : ORIGIN = 0x08100000, LENGTH = 1024K M7 .ld File FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K With the above settings I can run Core M7 and M4 properly.I need more flash on the m7 side a...
