Options – Talking to DevicesOptions – Talking to Devices• In looking at parts and specs, you’ll be seeing a lot of different “protocols” for

device interaction.

• The biggest question to ask is: “How can I connect this to our MPC555?”

Q1: Processor InterfacingQ1: Processor Interfacing

• What does the 555 support?

CS 478: Microcontroller SystemsUniversity of Wisconsin-Eau Claire Dan Ernst

What are these things?What are these things?• QSMCM – queued serial module

– Fancy name for “serial port”

• TouCAN (CAN port) – Controller Area Network– More complicated serial connection

• “50 channel timer system”– TPU3 – “Time Processing Unit”

• Complex “co-processor” for generating and collecting signals– MIOS1 – “Modular I/O System”

• Simpler I/O setup which can also perform some timing and input capture

• QADC64 – “Dual Queued Analog-to-Digital Converters”

• Reference for operation: MPC555 User’s Manual
