Hello All, Can any one advise me on a circuit/device which can generate pulses every minute or more (i am thinking of 1-5 minutes ). The circuit needs to ,preferably, be on the I2C bus. I have looked at the PCF8583 (8-pin device) but i need to reset the Interrupt bij Software and that is not what i want. Intention is to make a battery charger with a 16F84 and checks the voltage every 1 to 5 minutes. I do not want to use internal wdt's/counters or anything else cause this 16F84 has to do more jobs. grtz, Simon ____________________________________________________________ Do You Yahoo!?
