Creating Circuit Boards

Quad DAC (Digital to Anlog Convert) MCP4728

ADC (Analog to Digital conversion)

Need to be able to measure analog inputs, such as rudder and pitch controls, and convert to values suitable for X-Plane simulator inputs. e.g., 2.3 V from a rudder potentiometer, to -12 degrees for the X-Plane simulator.

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 8×8 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.

Changed code that runs on Raspberry Pi to drive the HT16K33. Arduino not required for this. It does work, but could use some improvement, where it draws lines more than just a dot for the aileron/elevator intersection.

Boolean analog to digital conversion

Need to be able to detect switch position, such as “beacon lights on” and convert to a true/false value for the X-Plane simulator.

Similarly, need to be able to group switch positions, such as flap selector switch, and convert to a digital number value, such as flap 25% deployment.

Smart Controller

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.

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]
