pause problem on 16f73
yes it is the same board witht the lcd. i dont have the schematics for the board. the board has al surface mount components and i am trouble telling what ALL the parts are. i have figured alot out but not everything. i know the hardware will work because these boards have porgrams on them right now and work fine with the old code. i have erased one of them to use as my "test board" and have made no hardware changes.
the designer of the board, as it seems, did many things wrong. the designer
1:did not use a resistor on the soleniads npn base.
2:doesnt have any resistors to the inputs on portB, which cantains most
input buttons.
3: i think that there is a diode across the solenoid though.
4:solenoid is a 5vdc. it is driven by sinking. i got 9 volt going to a Vreg 5+, an that 5+ going to the red wire of the solenoid. the black wire goes to the collector of the npn.
( i am going to make a picture/table. im also going to try and create a schemati for you.)
