ProgrammingFor newer PICs, the picprog programmer needs to be Modified. SX chips should best be programmed with the SX-Key or the SX-Blitz. Although almost each project could be done with an SX as well as a specific PIC chip, the approach and philosophy between both is quite different. Look at the differences between the SX and the PIC we found (on the internet) and discovered (ourselves) between the two competitors. A very useful utility for programming timing loops is PicLoops. It works for SX as well as PIC. And how can you program a SOT23 package (i.e. the 10Fxxx series)? With a SOT23-to-DIL adapter. Atmel has released a 4K version of the well-known Attiny2313, called the Attiny4313. It is fully (pin) compatible, with the only difference that it has double memory. The Attiny4313 is not yet recognized by Avrdude, so we have modified the Avrdude config file to be able to program it. This link contains the Attiny4313 section that should be added to your config. TutorialsAs there are many, many tutorials about PICs on the internet, and the SX is very well documented by Parallax, we won't be serving another one here. You might want to know how to run avrdude from eclipse under linux. Nowadays, we prefer to do our stuff in SMT. Why? Because it avoids the bore of drilling holes. And you can make use of cheap SMT resistor and capacitor assortments, so you'll always have the right values available. Working in SMT requires making PCB. We use the laserprinter/iron method. One tip: the ironing sticks much better if the paper is wet. And one other tip: etching in CupricChloride works very well and you never run out of etchant!
