Martin ROGER / VXDash - History

Schematic pre-review

WIP - final TODOs needed before review

WIP

Main schematic re-layout.
Updated 12V power input circuit.
SMPS regulators changed.
Updated analogue voltage circuit.

PCB update

To reflect pin reassignments

Multiple issues !! Read comment

Counter_3 moved to non-ADC GPIO18
Moved away from trying to put two ISRs on the same pin (you would think the IDE tells you off...)
Tried GPIO4 for Counter3 but seemed to perturbate ADC2 for the high KR analog
Should retry with the sorted double interrupt but no guarantee this will resolve things
Updated schematics with currently GPIO4, may need to move to GPIO18 also in schematics and PCB and kill one of the digitals

Minor corrections

- C35 and C36 were swapped on the silkscreen
- RV1 holes were too small, enlarged to 0.85mm
- Regenerated BOM and schematic files
- Updated HMI and Code to latest versions from benchboard

Housekeeping update - 1.2.2

Version numbers updated to 1.2.2 for the schematic and PCB
Components identified, datasheet and descriptions updated
iBOM regenerated
PCB plots regenerated
PCB :
- only thermal reliefs on PTH, not on SMD pads
- couple GND islands taken care of
- couple rationalisations on the 3v3 rails
