Memory-Mapped IO
LPC 1768 (system-on-chip, microcontroller) System Diagram
- UART: serial communication
- SPI: 4 wire bus for talking to other stuff (processors)
- I2C: 2 wire bus for connecting to microcontrolers
- WDT: watchdog timer, for autonomous systems, your code must periodically reset the timer or your code will re-boot (since you can't manually reset the system)
