Using an STM32H723 I started with a non interrupt USART connection onto a wifi module.I set up the connection on UART3 implementing nothing more than that and using these instructions int len = sprintf(tx_buff,"AT+GMR\r\n");HAL_UART_Transmit(&huart3...

Hello All,I designed and built a bare metal board with an STM32H723ZGT6 and it runs fine.I have blinking LED's, timer / interrupts running, HSE and LSE etc.I have been trying to figure out why if I toggle the power supply the device will not boot up ...

I have a bare metal board with an STM32H723ZGT6.I can connect and program the device.Initially I tried to use the HAL_Delay function but I found it hung the program never returning.This I determined by illuminating an LED on each side of the function...

Trying to connect to a STM32H723ZGT6 for the first time. Does the ST/LINK-V/2 have to use the JTAG connection on this device as I feel it probably does? The 4 pin connection being for the STM8 only? I jave connected as a JTAG connection using jumper ...

I have had a couple of Nucleo 144 test/demo boards for a couple of years and have had no issues with them.So I decided to try and create the simplest PCB from scratch.What is happening is the chip itself is resetting when powered with a repeated sign...

Thank you ... confirms I have to call the receive function to make the interrupt occur.I will experiment with that as the length is not fixed it varies.

As I explained above it might be how I view the USART module and trying to interact with it is not as expected.I never use those instructions so I never prepared the device USART state to receive the data.I did set the NVIC for the device in the IOC ...

I got confused at one point as there are 3 different types of UART/USART communication in the HAL.These are my steps ... So instruction used. HAL_UART_Transmit(&huart3,tx_buff,len,100);The reply is received polling. So I opened up the IOC and...

I found the solution so this is for anybody else.I did not fully understand the BOOT0 pin on the STM32H723ZGT6.This changes the program memory start execution.I was not sure of this so had made my bare metal board optional that I could switch using a...
