[...] using my PIC. It has USART pins. So is it possible for me to use my PIC? I'm using 18F452. When I using a usb break out board, is ther any crash because pc is UART and my pic is USART?
The '452 has got an AUSART (Addressable Universal Asynchronous Receiver Transmitter, The "S" just means "Serial" (as opposed to parallel) which they all are, synchronous or asynchronous, so the "S" is quite superfluous
AUSART means: Addressable Universal Synchronous Asynchronous Receiver Transmitter.It does have a Synchronous mode but the most common usage is for Asynchronous with an RS232 level translator.
and Addressable Universal Asynchronous Receiver Transmitter (AUSART)
Thank you for all advice,,According to your opinion PC>>>>USB PORT>>>USB CABLE>>>USB BREAKOUT BOARD>>>>PIC(18f452)>>>MOTOR CONTROLLER>>>MOTORIs this impossible or difficult to do???I already have done rs232. That's why now I'm trying for usb mode.
Usb breakout board has GND , D+ , D- and VBUS . The problem I have is where to connect these output? PIC 18F452 has TX and RX two pins. When I use a RS232 board there was direct two output for PIC RX and TX pins. But in this case I have no idea about how to connect output to my PIC. Can anyone please help about that case.
