| main | Example of usage |
| spi | MCP413X/415X/423X/425X
Max STEPS (128 or 256) and Max Resistance (5, 10, 50, 100 kOhm) depend on model of unit.
STEP 0 = max resistance. |
| digipot-read-wiper | Read the steps from digipot wiper
Pot2 -> true for reading the 2nd wiper. |
| digipot-write-step | MCP413X/415X/423X/425X
Max STEPS (128 or 256) and Max Resistance (5, 10, 50, 100 kOhm) depend on model of unit.
STEP 0 = max resistance. |
| digipot-increment | MCP413X/415X/423X/425X
Max STEPS (128 or 256) and Max Resistance (5, 10, 50, 100 kOhm) depend on model of unit.
STEP 0 = max resistance. |
| digipot-write-to-class | MCP413X/415X/423X/425X
Max STEPS (128 or 256) and Max Resistance (5, 10, 50, 100 kOhm) depend on model of unit.
STEP 0 = max resistance. |
| digipot-class | (Not Implemented) MCP413X/415X/423X/425X
Max STEPS (128 or 256) and Max Resistance (5, 10, 50, 100 kOhm) |
| digipot-decrement | Decrease the Step on the wiper by 1 step |
| digipot-kohm-to-step | Example applying math to the parameters of the device to select the resistance, Ohms, you want. |
