I am using the SPBTLE-1S module and sending some packets using RS485. Based on the chat example, i am using the printf() function to send the bytes from UART-> RS485 IC -> RS485 bus.
Here's the problem: Before use the printf() function i set the DE/!RE to '1' and after transmit i must set them to '0'. I am using the Clock_Wait() but it's not safe/right.
I want an interrupt vector to inform me when a transmission is finished. Could anyone help ?
