HOW to use uart

[ekeng86]

i want to know, how i want send data through uart, for ur info im used ccs compiler, i used while (1){
printf("OG>\n\r");
delay_ms(1000);
printf("S,100\n\r");
delay_ms(1000);

so motor will on and run forward with speed '100'

is it correct?

hi ekeng86,

have a question here, are u trying to control your motor using microcontroller?
if yes, then b4 UART can function, u will need some initializations of the uart module: enabling the serial port, setting the baudrate correct, setting the tris. setting the pin as digital inout.
after done all these. u can send data by loading data byte into the transmit register or receiving data by copying data received from receive register. PIC datasheet will help a lot to understand HOW to use uart.

regards,
yh

I don't know what your system. What relationship UART communication with motor?
If using UART, you should have 2 device. That is UART transmitter part and UART receiver part. The both device, can be a microcontroller. Then, the motor is at receiver part.

ekeng86, please explain in detail what you plan to do. We do not know which motor you are controlling, if through UART, what is the protocol? How is the connection, etc.
