MeterBoard/16A is a module for the MeterBoard system that drives 16 analog meters.
Status
- 2014-11-09: Started putting together initial design.
Specs
- SPI interface to MeterBoard system.
- 16 buffered analog outputs that can source 50mA each (configurable per-channel levels via resistors)
- 8-bit outputs resolution, so at 50mV full-scale each step is 190uV
- ~1/3 degree steps on a 90 degree regular meter
- ~1 degree steps on a 240 degree long-scale meter
- 8-bit outputs resolution, so at 50mV full-scale each step is 190uV
