Does anyone know where to get/find the source code of pic microcontroller program used for the adapter here? www.playvectrex.com/vectech/controller.txti want to try and build an adapter for 3 button game pad but will need the pic code to de-multiplex the start and fire buttons to single line outputs. Eg. Start will become button 1 i could probably figure it out myself but if it's available that would be great. thanks |

I've no plan about pic's but I've programed some avr's and I guess I could write an program for the attiny24 (or similar) to do the same job.

i have found some code for arduino so think i will use one of those.

not sure if arduino can be reduced down to a minimal DIP microprocessor chip - seen the development boards but they seem really quite complicated

if you have a source it should be easy to adopt it to not using arduino and thus you could use an attint24 (20 pin dip) with internal clock

attiny85 is even cheaper

yes, but it lacks of many io pins which are required!
if I read the pic schematics correctly 11 io pins + led/vcc/gnd/... are required.
(oh, and the attiny24 has only 14 pins in total , not 20 - I wrote that wrong)

i was thinking atmega8 will checkout you suggestions

attiny24 might do it with 12 io pins

you could use the 8 pin version with some 74xx chips too but then might as well spend it on more io pins on a ucontroller eh?
