solenoid_driver:
STM32CubeIDE-Projects for the Microcontroller (STM32F411, BlackPill V3 designed by WeAct), used to controll the hardware, especially the solenoids. Represents main processor in this project -
matrix controller:
STM32CubeIDE-Projects for the Microcontroller (STM32F411) to sample light dependent resistors in a matrix of 8x11 and send via USB on request -
matrix simulation dev:
STM32CubeIDE-Project for a µC to send random data to simulate the matrix, as it was not finished yet -
pinbal detection V0:
STM32CubeIDE for breadboard prototype of LDR matrix with a 4x4 matrix -
AVR:
contains FreeRTOS implementation on ATMega2560 (Arduino Mega). Main project lies in PlatformIO workspace, the Arduino_FreeRTOS port is used, as the native didn't feel like running
Multi-Tasking firmware with custom drivers for ADC and UART for effective data throughput reads pins for sensors, targets, Raspberry Pi output, button input, etc.
To get this thing up and running, 2 Raspberry were used, but only 1 is also sufficient.
All matrices were connected via USB-C cables to the Raspberry, appearing as ACM0 and ACM1 (numbering can be different), the ATMega2560 was connected via a FTDI USB to Serial adapter, as this will show up as USB0, so can be easily identified.
A strong 5V power supply is needed to prevent low power warnings on the raspberry and the Arduino to brown-out!
Having a common ground between the Raspberry with the control output and the ATMega2560 with the input for the flipper pins is also important, and is given when connecting either a jumper wire between the two, or having the ATMega2560 be powered from the Raspberry Pi.
Getting the score board script to automaticly open the port did not work in our case, so it has to be started manually. Also the c++-programm for autonomous playing needs to be started manually.
