For data transfer between STM32 and FPGA there are 4 pins needed at maximum (SPI for instance). The STM32 will be used and most STM32 boards have enough I/O pins for our needs. The STM32 F030 and F091 provided by Avans both have 15 digital pins and 6 analog pins. The buttons will be connected as follows: - + To implement the input in the game, the input should be checked at the start of each game cycle. In this case there are no interrupts needed. |
