| - | ==== Multiplexing ==== | ||
| - | |||
| - | The Raspberry Pi has two outputs which are I2C, sort of like USB. In order to drive the high quantity of analog outputs, a multiplexing scheme will need to be developed, both in hardware and in software. This is because each device must have a unique address. | ||

| The Arduino can measure an analog signal without any additional components. 10 bits - 0 to 1023 value output. | The Arduino can measure an analog signal without any additional components. 10 bits - 0 to 1023 value output. | ||
| - | ==== HT16K33 LED Module ==== | ||
| - | Purchased 3-pack of 8x8 LED modules (all red) with embedded HT16K33 multiplexer. Problem is, the code for this is from an Arduino, and the Arduino must be a Master, which won't work when the Raspberry Pi is the Master. | ||

| It is intended that there be a small computer (initially proposed as Raspberry Pi) which will server as a smart interface between the hardware controls and outputs. This computer will have its own display which can show local values and allows comprehensive calibration. | It is intended that there be a small computer (initially proposed as Raspberry Pi) which will server as a smart interface between the hardware controls and outputs.

| - | Because this display uses pin A4, and so does I2C, I'm concerned that this won't work with my I2C bus system. Ordering Arduino Mega 2560 clone, which uses different pins for I2C. [2/8/2020] | ||
