Here we are generating a PWM signal having 250ms, 125ms and 50ms pulse widths. Basic program for beginner.This program to consider port P1 as input and P2 as output.Send the value of P1 to Port P2 with some delay.keil basicprogram pr. at 15:49 Add a comment 1 I guess that you are asking about how to establish a connection to the AT89C51 (click for data sheet). PWM signals have many application in real world applications example to control the speed of the DC motor. Yes, Power cn be supplied t th QSB using 7-12V DC supply too, Power supply connection can be selected between the DC supply and USB power using the. No, ATMELPHILIPS lSP Programmer is rquired for loading th program on t the controller n the QSB. Pulse Width Modulated signal (PWM) using Timers: In this illustration program is loaded to the controller using the ATMEL Programmer. ![]()
