A budget friendly LTC/TimeCode device built from a RaspberryPi Pico - using the PIO blocks and MicroPython
I drew up a schematic and laid out a PCB for Rev-1 of the hardware, the audio interface is needed to amp/buffer the audio LTC signal into digital signals to/from...
As development moves forward, I'll 'open the floor' to suggestions from every/anyone. The following are on my list: - Button footprints for displays without buttons - Connections for I2C 7-seg...
In logging the data during the calibration process, I notice that sometimes the timestamp is missing... which caused glitches in the plotted data ``` [548.866017 0.988578] 02:27:30:01 0.0006966665 -3.433942e-05 -0.6695886...
As mentioned on #4 we have a way to assess the XTAL accuracy by performing a calibration process, and logging the results. I have/am writing scripts to automate this process...
I have a couple of Sony cameras without an audio jack, so I was wondering.... and ended up going down a massive rabbit hole. The Multi-Shoe is described: https://en.wikipedia.org/wiki/Multi_Interface_Shoe It...
Thought crossed my mind, can we power the Pico (or other board) from the 'phantom power' provided via camera's mic port? If so, we could make 'pico-timecode' into a dongle...
When monitoring an external device, with a Pico modified with high precision TCXO I see glitches.  These are not 'real' in the sense that (presumably) the relative phases of...
It would seem that the stock XTAL (with current code implementation) is not meeting the timing accuracy required - less than 1frame drift in 8hours. Fortunately we can replace the...
