Thanks for your help. the hardware is working fine ,the problem was with the pic.
how to store the last values of the led's to internal ram??
i don't know how to use internal ram can you please give one example to do this
- - - Updated - - -
changed as while(SW_PORT != 0xF7); but not working
the switch read values in your code are d6,d5,d3,c7,97 ,but in this case ra5 (reset pin) is treated as '0' at the same time it is connected with vcc via 10k
if((SW_PORT & SW_TEST_VAL) == 0xD6) {
Delay_ms(80)...
pic and the buttons are in working condition. When i use the code in post #1 all are working except pwm
can you please explain these lines
while((SW_PORT & 0xF7) != 0xF7);
#define SW_TEST_VAL 0xD7
The circuit is attached . In this ckt the switches are working with the hex code in post #1,in real hardware .pwm is not working .
but when i tried with the code& ckt in post#5 only the pwm led is high and the switches are not working when tested in hardwire
