IR controller made with Raspberry Pi Pico
Connect a Raspberry Pi Pico to the other parts as follows. Note that the value of resistor connected to IR-LED is between 10 to 150 ohms depending upon the LED performance.
The 32 bit IR codes can be obtained by using MachiKania with IR_RX class. See the help.txt as an example code to get 32 bit values.
Maximum 25 buttons can be used. Current code and schematic is an example using seven buttons.
