in a project, I’m thinking About using Dashbox from SPLeinonen.
I’m missing a few digital Inputs, but I think analog Inputs will also work and to the Transition to 0/1 in RealDash.
Due to the fact it’s an old car, I wonder how to do the calculation for Speed (i just have a speedpulse source) and RPM (number of ignition pulses) ?
Analog inputs work just in the way you describe. There is 2pcs 0-18V inputs and those are good also for +12V.
Are You able to use GPS? It’s been quite popular and it is also accurate. What kind of speedpulse source You have? Is it VR or Hall type sensor? I have been thinking to do converter inside box what read VR sensor pulses for speed but it’s here yet…
