I am trying to use H5 as master and UNO(ATmega328p) as slave and transmit data from UNO and receive a character & print it in the COM using USART3. The baud rate I've set for both is 4 MHz. By connecting them together and I can see that the "Tx " LED...
After the device powers on, lwIP works properly. I reboot it once using the code below, and it continues to function correctly. However, if I reboot it a second time with the same code, it stops working. It goes through the PCB initialization, but no...
Good afternoon, I'm writing this quick post to know if by any chance someone can help me figure out what is happening with a simple threading project I started on the H7S3L8 board. I'm using ThreadX and NetXDuo, to have a Modbus server on the ETH por...
Hi allI have used CubeMx to create an FMC interface to psram(nonmultiplex) 8-bit data 10-bit addressThe data is valid on the rising edge of the fourth clock To have correct data on the data pins the pointer to write data (psram64) must be a 64-bit po...
Dear all,I am using lwIP over STM32F4 and I would add REST API to my project.I try to understand how to do that, and the only way that I have found is to use CGI. The problem is the reply: I can reply only with a static file present in the SDCARD (th...
Hi, I have a problem. I want to store 262144 (256KB) bytes of data in a buffer from the integrated ADC on STM32H723ZG. However it fails when the buffer is too large. I started at an buffer size of 4096 elements (uint8_t) and doubled until 65536 where...
