使用 DAC 用于扬声器、操纵杆、2 个按钮 4 个 IRQ，用于游戏引擎、攻击和声音

# Undertale-in-C-on-MSPM0G3507 # DAC runs on PB0 through PB4 # Two buttons initialized and connected to PB6 and PB12 # Joystick is very confusing. Connecting x to PB19 and y to PA22 works, however it is NOT initialized to this, and the ports it is initialized to don't work. I'm not sure why this happens, but... whatever. # There is joystick button code, however my joystick was broken so I'm unsure if it works. # LCD connections: # For ST7735 # LED- (pin 16) TFT, to ground # LED+ (pin 15) TFT, to +3.3 V # SD_CS (pin 14) SDC, to chip select # MOSI (pin 13) SDC, to MOSI # MISO (pin 12) SDC, to MISO # SCK (pin 11) SDC, to serial clock # CS (pin 10) TFT, to PB6 SPI1 CS0 # SCL (pin 9) TFT, to PB9 SPI1 SCLK # SDA (pin 8) TFT, to PB8 MOSI SPI1 PICO # A0 (pin 7) TFT, to PA13 Data/Command, high for data, low for command # RESET (pin 6) TFT, to PB15 reset (GPIO), low to reset # NC (pins 3,4,5) # VCC (pin 2) to +3.3 V # GND (pin 1) to ground # if you have any questions or need help feel free to message me here or on Instagram @germanwaffles
