Hi Jim,
I am familiar with Fritzing app - before I stumbled upon DIYLC, this is what I started with. However, the stripboard which is available has two columns which are cut in the middle rows 5 and 15 - and there are components, such as the 2-pin JST-XH that don't exist - found a couple libraries, but there are challenges - the JST-XH library is visual only and doesnt work with simulation or schematic.
For now (next few days), I don't want to sidestep to learn how to make my own Fritzing parts - DIYLC is easier to use. Making the Illustrator schematic was fast & simple. If these are not acceptable to post here, I understand, and won't post my DIYLC/Illustrator again until I can produce a suitable Fritzing diagram. Is that the message I should take here?
Reference Voltage
You gave me more to think about - thanks.
I understand your point about the 6-10% error - I was thinking of calibrating for THIS box, and calculating the offset (slope) and storing in EEPROM.
The only sensor data that is dynamic is hydraulic - air is very steady and a little noise is ok. The hydraulic is at most 100hz. The air signal jumps around here, but was due to compressor issues.
I need to ensure I have the correct layout the Schottsky clamp, & that I understand the layout ins/outs with the splitboard - once this is complete, today or tomorrow, then will work on the final bit with reference voltage.
