I recently switched from DMA to IT for receiving commands via SPI. Now I'm noticing that commands are being received and processed correctly, but HAL_SPI_RxHalfCpltCallback() is no longer being called. A lot has changed in my program since then, but ...
Hi Team,I am using the stm32h745-dico board. I am trying to trasmitt and receive the data using DMA through the UART1 from the PB6 & PB7 . Is there any specific streams for Rx and Tx for particular UART.when I am working with the UART3 I used strea...
Hello,I'm curious if there is any way how to load correctly linked elf file into the SDRAM of st32h757i-eval board. By correctly linked elf I mean everything is either linked into SDRAM or to some of the SRAMs. E.g. readelf -S of the elf looks:There ...
Dear ST Team, could you please update this section with correct information?There is incorrect text description or figure in RM0454 Rev 2 in section 14.10 (VBAT).Text: "...converted digital value is half the VBATvoltage."Figure: VBAT/3.
Have tried both Chrome and Edge and unable to access e-learning catalog courses. Keep getting same below error the last two days
I am from China,I was told that STM32 hardware I2C has bug.So I always use software simulation I2C with two ordinary GPIO Pins. I was wondering what is the bug exactly?Is it a rumor ,or is it true?I hope get opinion from abroad website,because you sp...
I've been tinkering around STM32 (L443VCT6) for a couple of weeks now and one thing I don't get is I'M USING THE ADC_IN 10 CHANNEL. MY ADC MEASUREMENT REMAINS THE VOLTAGE RANGE ON THE PIN LEGS, HOWEVER, MY ADC VALUE IS INCREASING. AFTER 4095 IT IS NO...
I am trying to encrypt part of my code and write back to internal flash. The MCU is STM32F407 and write to flash sector 3 (0x0800C000 - 0x0800FFFF). I customized the sct file to avoid other codes taking the place.The encrypted data takes 1Kbytes and ...
