WO2 stim

[jharvey]

I think a WO2 stim could be made with a simple stack of resistors between Vref and GND, generating a variety of voltages. To understand the voltages we want for a basic test stimulator, we could take some measures then find resistors to make that happen. Lost of great WO2 data at the below link.

With WO2 connected, could I get these voltages as indicated in the picture. Any multimeter would suffice. WO2 reading can be open air, I'm just looking for some kind of semi-sane reference. The resistor divider could emulate what ever this setting is, and could function as a basic spot check. The resistor divider equiv WO2 would eventually be integrated into the STIM board for testing purposes. Basically if new board reports this resistors WO2 reading is within a specific range, then newly MFGed board can be given a green light.
