After the first kivu12 board is assembled, make a first round of hardware test, before we test the software as in #180.

Stage 1

• DPSM is not connected
• No front panel connected
• Lab supply: max 100mA for all outputs

Tasks:

• [x] Proper ±12V with small current consumption
• [x] Connect kivu12/CI1 and kivu12/CI2 to 0V, 2.5V, -2.5V, 5V, -5V, Jumpers on position ±5V DPSM/C4 and DPSM/C5 are 0V, 2.5V, -2.5V, 5V, -5V
• [ ] ❌ Connect kivu12/CI1 and kivu12/CI2 to 0V, 4V, 8V, Jumpers on position 0..10V DPSM/C4 and DPSM/C5 are -5V, -1V, 3V
• [x] Connect DPSM/A2/A3/A9 to GND, kivu12/B2 to xV, DPSM/B9 is xV
• [x] Connect DPSM/A2/A3/A9 to GND, kivu12/B10 to xV, DPSM/B10 is xV

Stage 2

• DPSM is connected
• No front panel connected
• Lab supply: max 200mA for all outputs

Tasks:

• [x] Proper ±12V with small current consumption
• [x] Proper 3V3 on kivu12/3V3

When jumper position is 0..10V, whatever the input, the output is 10V because there was a mistake already in the schematics.

We can just correct it by using an inverting adder, and inverting back in software.

When connecting the DPSM:

• 12V takes around 110mA
• -12V takes around 10mA
