i have problem with the led blinking. I using the exmaple program given by keil using uVision3. When i run the program, the LED on the development board didnt blink, it just stay on! wat should i do?
thanks!
I have another question, how do I pass value from RFID to microcontroller? Do i need to use another port from microcontroller and connect it to RFID? or both RFID and microcontroller connect to the same computer?
Don't you think that your question requires a description of what type of interface the RFID has, and exactly how you have connected it?
