We're running into a really weird situation with a bootloader that copies some code into ITCM. The bootloader initializes various peripherals and clocks and then copies data from the QSPI flash to both the SRAM and to the ITCM memory. Then we use t...
HelloWe are using STM32H563VIT6 in our project. When the PCB was designed, our design team used PB13 and PB14 as TXD1 and TX_EN pins (from what I know, they were using CubeMX when designing the board). When I have started working on the board I was u...
Hey,Is it possible to create a seperate space on every microcontroller for a second bootloader and firmware location? To update the firmware live? Or is this only possible on specific series? A second firmware location to place the new firmware and t...
Hi,I try to comuunicate between STM32L443VCT6 and ultrasonic A02YYUW (By UART1) Just to make sure that the ultrasonic is working ok, i tested it by UART1 with model: stm32 neucler f441 and everthing works ok. This is the code for the STM32L443VCT6: ...
the picture 1 shows correct miso data，but sometimes the last bit of miso was set to 1 like picture2and the voltage will drop down slowly, even affect the next data other wires are no problemthe mcu is stm32f411ceu6 and spi1 is used between stm32 and...
I have an STM32F103C8T6 Blue Pill board, and I'm trying to get the RTC to function correctly when Vdd is removed. However, when I disconnect Vdd, the RTC doesn't operate as expected. Sometimes, when Vdd is supplied, the RTC starts counting from the t...
Hi i am using stm32f767IGK6 i am able to write data in nor flash but can't read data of same address. by use this APIs HAL_QSPI_Transmit(), HAL_QSPI_Receive() Regard & Thanks, Naresh
Heyho,using all SAI blocks on H723 / H733 / H735 with stereo audio ADCs via DMA, working smoothly as long as both channels are used.Now I wanted to implement turning off single channels, and I thought I could do that with the SAI / DMA settings.I jus...
Hi,i wrote code that wait for a ping from esp32 and when he got it, it sent back pong to esp32In the uart1 everthing works fine, but i do not understand why, in uart2 it is not workingI doubled checked the code and everthing looks ok for me, The cod...
