Hi There 馃憢

Welcome! I enjoy designing and building electronics. Here I’ll document electronics projects I work on in a bit more detail than I can do on twitter. Basically this is just the same images I put on twitter, but with some more words padding them out.

MSP430 custom ezFET Lite

Summary Texas Instruments has a range of 16 bit microcontrollers, the MSP430. To program these require what they call a Flash Emulation Tool (FET). Thankfully all their affordable development kits contain a small stripped down FET, known as the ezFET Lite. TI has open sourced this design and provide both the firmware and the schematics. I was given a tag-connect cable as a giveaway through the 43oh, MSP430 community forum....

Boson Frame Grabber Part 5

RTL Architecture The original version of the frame grabbing PCB used an iCE40 HX8K FPGA. This turned out to be a little small for the features I wanted to add. I managed to get it to a state where it would capture images from the Boson 320, but everything was hardwired together, and not easy to alter or reuse. In order to improve module reuse and extendability a standard interface should be used....

Boson Frame Grabber Part 4

The new hardware for the Boson Frame Grabber will be based around the Lattice ECP5 family. Lattice make available a free IDE for this FPGA assuming you are not using a model with embedded SERDES. Since we are not, it鈥檚 perfect for our application. ...
