Martin ROGER / VXDash - History

Comments

@Alex-XNR
Just confirmed with comments to educate me.
I think the only point that remains open is the question of Rf and Ri ? I can't remember where I saw they were included and I can't see, to find anymore.
For the higher resistance I/O I think I will try with a higher Iset resistor ? With my crappy simulator it seems to run.

Added simulation files

LTspice simulation files for reference

Updated OpAmp CC circuit

Used MOSFET instead of BJT.
Reduced Vref to 100mV to increase headroom.

Squashed commit of the following:

Fonts reshape

Stress testing might be a bit too stress intensive, so next stages are :
- [ ] Implementing quantization
- [ ] Implementing limited Serial traffic

Initial stress testing program running

A lot of segmentation on long progress bars doing fast sweeps (like RPM for example
No value-repetition check on maths that are being sent over
Monospaced fonts are a must

Added first draft of Op-amp based circuitry

Also some rationalisation of the components to avoid near-duplicates (e.g. 0.1uF 50V caps)

Pre-PCB update

Schematic draft OK
