This uses a Serial connection to transmit data for 2 Rev Color Sensors to a roboRIO using a Pi Pico.
You can follow the raspberry pi instructions to build the executable in the pico folder. Their instructions are complicated for windows, so I have also provided a prebuilt uf2 file to directly upload to the device. To deploy this file this, hold down the button on your devide, and connect to your computer. This will open as a drive. Copy the picocolorsensor.uf2 file in the pico folder to the drive. It will automatically reboot and start running the code with no configuration required.
By default, the code will connect to 2 color sensors.
Please solder all the necessary components onto the PCB, files are provided in the Pico Color Sensor PCB folder to print/order your own PCB as well as the Bill of Materials(BOM) needed for the PCB.
You may solder both the DuPont and/or the JST connector but you may only use one on both sides.
V2
Differences between V1 and V2:
- Replaced the SMDs with THTs components so teams don’t need to worry about small pieces and allows easier soldering with THTs
- Made the DuPont headers at a right angle to minimize the usage of the vertical space
- Both the Dupont and JST connector face the side
- FIXED: The JST connector on the V1 had the SDA and SCL channels in the wrong pins, V2 has fixed that. This allows you to use a regular 4-pin JST PH cable from the color sensor to the board. NOTE: When plugging the JST connector into the board, the connector must be upside down then how you plug into the color sensor.
V2.1
V2.5
Differences between V2 and V2.1/V2.5
- V2.1 and V2.5 now have 4 layers of traces instead of 2
Differences between V2.1 and V2.5
- V2.5 now has a male MXP port to allow you to use a NavX.
- V2.5 also has extra mounting holes for you to be able to securely mount the NavX
- NOTE: Due to the rule R713 in the 2022 Game Manual, you are not allowed to use any of the pins available on the NavX to control any actuators
Copy the files corresponding to the language you use in the wpilib folder into your project. Instantiate a PicoColorSensor (java) or pico::ColorSensor (C++) object. You can only create 1 instance of this object. You can then use the functions to grab each color sensors value, and if its connected.
