#100731 - watchdog fed from ISP Responding to: ???'s previous message |
Erik Malund said: Yep.
do you mean the st pin or td pin
He means neither, the 1232 WILL issue a reset periodically if the watchdog is not fed. Erik Malund said:
There is no way the ISP code can feed an external watchdog, how can someone like e.g. Andy Ayre anticipate which pin you connect the puppy tickler to. However, some of the better ISP code will take care of an internal watchdog. Well I don't think even if Andy Ayre would know which pin is the watchdog reset, he can do anything from the PC side. But if you don't constrain yourself to the default/internal ISP code, you can write your own ISP, why not. Yes it's tricky but if you REALLY want it... For the time being, what about putting a jumper from ALE to the watchdog reset while being ISP'd... Jan Waclawek |
