| what is it that ur code is doing?? u are not reading the TH/TL values anywhere. the logical flow in the external interrupt routine should be as follows: 1. read the TH0/TL0 values and store them in som... |

| PWM implementation on 8051 help |
| duty cycle would be (160/256) x 100 % (assuming a high on the port pin turns on ur external device) and never put ur interrupt routine inside another function. In ur code, terminate ur function pwm_se... |

| u r right about the voltage levels . sorry about the error on my part. and yes, u can use any op-amp as a comparator as long as it can handle the frequency of the input signal. if ur input frequency (... |

| need help to write code for 8051 |
| no, the question is not silly but perfectly valid :-). actually, apart from the standard character set, the table also contains some special key scan cods like the function keys F0-F10 on the keyboard... |

| as u mentioned the output fluctuates between 2.2V and 2.6V. So keep the reference voltage on the other arm of the comparator between 2.6V and 4.0V if u want a high logic on idle state OR keep it anywh... |

| i think u need to use a comparator prior to giving the signal to the uC solely because the voltage on idle state is 2.8V which is not a purely digital level for the uC. |

| if it is a 'c' program, hope u have selected the right device before creating the project. To cross check, go to Project -> configuration otions -> general where u will find the device selected. Also c... |
