The defines range in basically two categories: ATmega8 compatible and ATmega 168 compatible. The Atmega88 is 168 compatible, the mega32 for example is mega8 compatible. With compatible, I mean congruent in register definitions, not memory size etc. In order to work with more controllers, the #if defined(__ATmega8__) has to be extended with an || defined … text/html 2009-10-13T09:57:50+01:00 edwin prototyping:workflow http://wiki.edwindertien.nl/doku.php?id=prototyping:workflow&rev=1255420670&do=diff checkout FabLabs: <http://protospace.nl> Important lessons the first 90% takes 10% of the time the last 10% takes 90% of the time If there's no time, prepare to expect only 90% text/html 2009-10-08T21:16:48+01:00 edwin installations:leddimmer http://wiki.edwindertien.nl/doku.php?id=installations:leddimmer&rev=1255029408&do=diff This page describes a 40-channel LED strip dimmer project. Electronics Board layout Modular driver boards consisting of an ATmega88 running at 16 MHz. The boards use 8 IRF44 power MOSFET's driven by 4423 MOSFET driver chips. Room has been left for adding RS485 driver control, DIP switches for address selection and status LED's. These are for future additions.
