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 […]
Tom Keddie writes: This week at VHS we’re building Logic Pirates in our SMD workshops. The LP is an awesome little open hardware logic analyser design from DP. The ICSP header is a tiny 0.05″ pitch, I struggled with this a little until I came up with this top and bottom 0.1″ jig (obvious in […]
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 […]
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 […]
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.
Menno posts several alternatives to using pin headers for programming microcontrollers. Most use spring loaded pogo-pins make contact with the programming signal pads. Check out more pictures on his Flickr page. Via the forum.
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 […]
Can one Bus Pirate program another? Not yet, but we’ve been hard at work on it. This post is about a new application, available here, that will program PIC 24Fs from the Bus Pirate. Everything looks great on a logic analyzer, but it’s not working yet. Maybe you can help us figure it out, and […]
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 […]
