this was my hardware setup manually controlling the boot pin.what my condition was I am initialized the bootloader receiving the ack 0x79 for that and also erasing the flash correctly i checked it with the cube programmer , but the write operation i...
Hi, I am having several days problems with connecting ST-Link to gdb server to debug. I am using ST-Link V3, V2 (genuine ones).Everything was working fine until I connected Copy of a ST-Link debugger (I didn't know it is copy, it has original logo on...
Edit by ST Moderator: This post has been translated from Chinese to comply with the ST Community Terms and Conditions (§10.2). What is the difference between STM32F070F6 and STM32F070F6P6TR? STM32F070F6和STM32F070F6P6TR的区别是什么呢？
Hi,I am using STM32H753ZI nucleo board, developing with Keil IDE. I am using UART RX and TX DMA. I want to check if there is a possibility of corruption of UART data while transmitting with DMA Tx.The sending device will send 8-byte defined command t...
I am currently working with the STM32H7S7I8T6 microcontroller and have selected IS42S16400N-7TL as the external SDRAM.I would like to interface both SDRAM and an LTDC display with this MCU. However, I’m facing issues because some of the required pins...
HiI got a new STM32F407VGT6 Dicovery board which is quite awesome. I have been playing with it and now I want to print stuff to a terminal via Serial. I looked up some tutotials and there they simply use the on board STLink becasue USART pins are con...
Hi, I am facing an issue on STM32F469 where UART is not initialized with DMA properly if I dont add some delay around 300ms as show in my initialization. /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); ...
STM32L432KC Nucleo GPIOA resets to 0xABFF FFEF instead of 0xABFF FFFFI can't write 0 to $4800 0000 [GPIOA_MODER]Ports B and C behave as expected: the correct reset values and it is possible to write 0x0000 0000 to B and C.How can I resolve this?Or ha...
on H743 board (DevEboard) I2S1 (master 16b 44k1) -> ES9038 DAC (I2S slave) : DAC playing music fine, ok. now switching DAC to I2S master , H743 to slave transmitter mode : no data / silence.test with DSO : pin PA7 (SDO) is tri state now! thats WRONG ...
Hello community ,I am newby trying to do a small project with STM nucleoh563zi and stumble upon following brickwall .I need to interface an Incremental encoder that produces 1000pulses per rotation and simply print it to com port and i searched a...
