compile error on nucleo-stm32f466re

[jaykorea]

Hello.

Recently, I'm on a project using stm32 with ros

I should use this library to communicate with ros node, but compile error occurs like below

Plz let me know what would cause this issue...

entire error message is below

cannot convert 'uint8_t (*)[1024] {aka unsigned char (*)[1024]}' to 'const uint8_t* {aka const unsigned char*}' for argument '2' to 'HAL_StatusTypeDef HAL_UART_Transmit_DMA(UART_HandleTypeDef*, const uint8_t*, uint16_t)'

Sincerely looking forward to your answer

Thanks

I had exactly the same error. I used this setup in a project for a STM32F767ZI, for this, I think it is following hardware - independent reason for the bug of the current commit of this repo:
original: HAL_UART_Transmit_DMA(huart, &(tbuf), twind);
fix: HAL_UART_Transmit_DMA(huart, (uint8_t*)&(tbuf), twind);

-> typecast (uint8_t*) for tbuf was missing, HAL_UART_Transmit_DMA seems to require everytime a const uint8_t *
