ICSP switch box

Stynus has published a new build: For a project I need to program a few microcontrollers in the same circuit. This meant I needed to plug the programmer around on the board a lot.¬† This got annoying very fast. Therefore I decided to make a switch box. In my junk pile I found an old […]

App note: PICmicro device programming, what you always wanted to know (but didn’t know who to ask)

The basics of how to get your firmware into your PIC microcontroller. App note can be found here. For more than a decade, Microchip has published a lot of information about programming its 8-bit microcontrollers. There is now so much information out there, in fact, that it’s sometimes hard for engineers and technicians who are […]

Another DIY programming pogo pin connector

Lately we’ve been experimenting with pogo pin connectors for programing our boards. Beth designed another DIY ICSP pogo pin connector using two PCBs to align the pogo pins properly. One board holds the pin connections, and the other stabilizes everything for alignment. In the end I decided to use two pcbs to make the pogo […]

Testing the new reduced-sized ICSP connector

This week we received a batch of PCBs and amongst them was the latest revision of our USB TFT breakoutboard. This board is the first board that features a new ICSP footprint, which occupies less space on the PCB and should improve testing and programming times at Seeed.

Universal PIC programming adapter

Development of the Bus Pirate PIC programmer involves testing a bunch of different chips. This $10 universal programming adapter from Sure Electronics will be really handy. This board doesn’t actually program any chips. It’s an adapter that accepts a lot of different 18-40pin PIC chips and connects the programming pins to a header. The ZIF […]

Bus Pirate high voltage programming adapter

Today we’re giving away an assembled Bus Pirate high-voltage programming adapter. It has a 5pin PIC programming header, a 6pin AVR programming header, and a small 13volt boost-converter power supply. A 13volt supply is needed to program PIC 12/16/18F microcontrollers, and clear the RESET fuse in AVRs. It’s doesn’t do much right now though, because […]
