UART IT

Question asked by grossi.marco on Dec 4, 2017

I am using Nucleo F334 and STM32 Workbench as IDE.

I need to build a bridge between UART2 and UART3. It should work this way: data are continously acquired on USART3_RX by interrupt and transmitted on USART2_TX.

I am using the HAL library but I can not understand how to implement it since the library has the function:

 

HAL_UART_Receive_IT(&huart3, (uint8_t*)ch1, strlen(ch1));

 

but the number of bytes to acquire must be specified. 

I can not understand how to make it acquire indefinitely.

 

Thanks.
