Salah satu software pemrograman AVR mikrokontroller adalah CodevisionAVR C Compiler versi 2.05.3 yang selanjutnya dalam pembahasan disebut cvAVR.
Footprints are well done for manual soldering. I started working on them today and it was done in 2 hours. It looks really good though so I can’t wait to turn it on and show it off. Would have slightly simplified the design. Lastly, I may have this wrong but the input impedance of the ADC is 100M so you could have done away with the PMOSFETs and just used a resistor network of say 2M without any problems. There is also a case to be made for using a solderable socket for the OLED screen ribbon, however I understand if you omitted this for cost or just couldn’t find one.Ĭould you provide a quick sketch of how you mounted the strap, PCBs, and screen together? I’m thinking of using a sticky pad between LCD and PCB but would be great to have your input on this. This provides better strain relief than at present where they are just soldered to the copper tracks. Secondly, I would have used switches and a USB socket that has through-hole metal prongs on it that you can bend over the on the other side of the board. The resistor networks were a bugger to solder as they’ve been placed so close to the AVR.
This makes soldering so much easier, plus if you want to modify the board for whatever reason, then that becomes easier too. Just a few tips firstly, I’d suggest if you have the space that you lay out components as evenly as possible and not packed together in the middle. Hi Zac, I’ve just soldered up my board but I’m going to inspect it first with a microscope before the turn on to check for solder short circuits.
