The overall objective is to redesign the Lab 6.2 or 6.3 data acquisition system to employ two microcontrollers. The slave microcontroller will perform the data acquisition (position or temperature), and the master microcontroller will interface to the PC. The two microcontrollers will be linked using their SPI ports, as shown in Figure 7.65. The master microcontroller will fetch data from the slave and transmit it to the PC, using SCI interrupt synchronization. The user will interact with a PC running HyperTerminal.
