I have tried everything to clear this error. Does anyone know what I am doing wrong and how to fix it? The error if pointing to the HAL_UART_Transmit_DMA call.uint8_t SPI_data[SPI_Buffer_Size] = {};HAL_UART_Transmit_DMA(RS485_1, SPI_data, strlen(SPI...

Here is my c++ code:void print_console(std::string msg){ const char *p = msg.c_str(); HAL_UART_Transmit_DMA(CONSOLE, p, strlen(msg)); while (console_tx_flag == 0); // Wait until the uart transmit is complete console_tx_flag = 0;}Does anyone know ...

I had a similar issue, for me it was the interrupt priority settings on the NVIC tab under Pinout and Configuration in CubeMX. Lower numbers are higher priority. I would also check the clocks for the USARTS to make sure they are adequate, check the...

I figured it out, thanks you: HAL_UART_Transmit_DMA(CONSOLE, (uint8_t *)p, strlen(p));

Question: Why does #include <string> require me to add the .h but #include <cstdio> chokes if I add the .h?

I am new to CubeIDE and have created a c++ project. I had the system generate the code and renamed main.c to main.cpp. I then put a #include <string> in the main and I get a fatal error during the build: "string: no such file or directory."
