#130132 - RC5 within interrupt Responding to: ???'s previous message |
Asok Sankar Rudra said:
What are the necessary conditions,precautions and limitations in trying to poll a sequence of about 25 milliSecond duration WITHIN a timer interrupt please? Dear Asok If I understood correctly, you are waiting within the EX1 ISR while reading the RC5 code. If this is true, then you have the problems you describe. I will suggest you try to break the RC5 ISR code to implement a state machine. With this, the ISR will receive a bit at a time and exit. When the entire RC5 code is received, the ISR will flag the main loop which will then take action appropriate to the code. Jerson |

| Couple of questions | 01/01/70 00:00 | |
| Do you disable interrputs when you are in ISR? | 01/01/70 00:00 | |
| use priority | 01/01/70 00:00 | |
