hello all,
I am working with AT89C51CC01.I want to see o/p of PWM using PCA. The code is as follows.
void main() { CMOD = 0x02; // Setup PCA timer CL = 0x00; CH = 0x00; CCAP0L = 0x40; // Initial value same as CCAP0H CCAP0H = 0x40; // 75% Duty Cycle CCAPM0 = 0x42; // PCA module 0 in PWM mode. CR = 1; // Start PCA Timer. while (1) {} }
I test this program last week that time this was working, but when i test today then it´s not gives o/p of PWM signals. I don´t understand wht is the problem? please give me ur suggetion for this problem. Thanks in advance.
