Hi everyone, I am trying to learn i2c communication between two stm32 microcontrollers. I am using stm32f407g Disk1 board as slave and stm32l100 disco as master I configured these boards I have provided source files below.can you give any suggestions...
Hi there,I have a custom board with an STM32F070. The VDD and VDDA are connected together. System runs at 48 MHz from a 8 MHz crystal. Each VDD has a 100nF cap. VDD is 3.3V, from a 1% LDO.The code uses UART1, UART2, USB and I2C2. Also, many I/O pins....
I'm trying to get a continuous GPDMA transfers from ADC4 into a buffer on a Nucleo-U5A5 board. I'm not using any security settings. It seems that the ADC conversion are working correctly. When debugging I can poll the DR and see the values change (...
Hi, Can we use any UART /USART port for debugging? or any dedicated port only i have to allocate for debugging purpose? what are the main application where USART can be used and UART cannot be used?
Hi all I want to understand behavior of TX mailbox here I am trying to send three ID but only i able to see two ID at a time in TI0R. I have fewer doubts which I hope you can clear. Doubt 1: Do I have to use three different mail box for three ID or ...
I don't know the function of the BIST receive mode bits in the picture. According to the description, when this bit is enabled, the protocol layer cannot receive data. So, what does this model do? Please help me resolve this confusion. Thanks *T...
Hi,I am using STM32H753XI in my ongoing design. We are using most of the timers and internal ADCs in our application. So it is very tough for me accommodate both external eMMC and NOR flash interface. My question is, Can we boot STM32H753 with exter...
Hello,I am writing a programm for a raspi cm4 to flash a programm on an STM32 using the UART bootloader. The raspi parses some hex file that I want to flash and sends data packets to the bootloader using the 0x31 write command. Here is what I have ac...
Hello everyoneI need to implement a protocol for an external ADC. An SPI read with 22 bits should be triggered via a timer in a 4us cycle. My procedure:TIM2 triggers a DMA transfer from the TxBuffer into the SPI->TXDR (with some zeros)Since CSTA...
Hi,We need an example configuration code with details of Audio data Received and getting Transmitted using Stm32F407G-DISC Board.In that example if it could have the details of without using any other External things how to receive the audio data thr...
