Another Crosspoint Update
My brain’s been churning on this one. I want to drive the MT8816, which requires 8 different bits plus a strobe and reset, I need discrete inputs and outputs, I…
Update on the 8816 Crosspoint Switch Project
Finally got my SN74LV8153 chips. Did some coding in the background, but without this chip, it wasn’t value added to mess with it. Mouser is 20 or 30 miles away.…
Yet ANOTHER Project… the MT8816 Crosspoint Switch
This one’s been in the works for a long time. I’ve always wanted to play with some sort of audio routing device. I’ve worked on a number of different airplanes.…
Still working on the Icom Project
It has been a LONG time since I seriously did any C programming… and structures were something we only vaguely touched on in class. I’ve already used up about 60%…
Icom External VFO and Control – revisited and revised
Well, I’m back to the Arduino <–> Icom projects. I just acquired an Icom 7300 – and found (according to others, as well) that it and the 7610 bury a…
CI-V EXTERNAL VFO CONTROL, PART 4
Today, I tackled interrupts. I’m not so sure I tackled interrupts, so much as i worked on determining the dynamic tuning step timing. I needed a routine to wait for…
CI-V EXTERNAL VFO CONTROL, PART 3
well, there’s been some small progress…. I started tinkering with the rotary encoder. I found a great example here: http://www.pjrc.com/teensy/td_libs_Encoder.html one thing, though – encoder.h must be added to the…
CI-V External VFO Control, Part 2
OK, this update won’t have any videos… those will come shortly, so you’ll need to take my word for it. I learned a few things since the last post… so…
CI-V External VFO Control, Part 1
Many years ago, Sam, K9SD, added some interesting functionality to his Icom 781 radios – an external encoder wired in parallel to the VFO control. This may seem trivial, but…
