Experiment Setup for IO Pin Interface Toggle with PGA460 Development Board

In this experiment setup, the onboard PGA460 is removed to establish communication with an external PGA460 Development board. The process involves reading registers in OWU mode, confirming specific bit settings, sending coded signals, and checking waveforms. Custom coding in Energia is utilized, along with monitoring through serial print functions. The results are checked using oscilloscope measurements. The final step involves confirming the IO_IF_SEL bit status using GUI and serial monitor. Detailed steps and visual representations are provided.

1. IO-Pin Interface Toggle - Experiment setup Removed onboard pga460 to ensure communicate with external pga460 PGA460 Development board

2. IO-Pin Interface Toggle Read register in OWU mode Read 0x1E register through custom program to confirm the IO_IF_SEL bit is set to 1 and using serial print function to print out the result Energia custom coding Result in Energia serial monitor

3. IO-Pin Interface Toggle OWU to TCI by sending 0xF0F8FC (Coding) The coding for send 0xF0F8FC using Serial1 (pin 4) is shown below.

4. IO-Pin Interface Toggle OWU to TCI by sending 0xF0F8FC (Waveform) Checked with Serial1 (pin 4) signal output oscilloscope (Send 0xF0F8FC), the waveform is shown below. 262us 318us 157us 262us 209us

5. IO-Pin Interface Toggle OWU to TCI by sending Time-Based pattern(Coding) The coding for send time-based pattern using pin 4 is shown below.

6. IO-Pin Interface Toggle OWU to TCI by sending Time-Based pattern (Waveform) Checked with pin 4 signal output using oscilloscope (Send time-based pattern), the waveform is shown below. 299us 331us 211us 252us 166us

7. IO-Pin Interface Toggle OWU to TCI (Result) Checked the IO_IF_SEL bit with GUI and serial monitor (Custom program) and the result is shown below The result is show FF, the pga460 IO_IF_SEL bit should already change to 0 Use GUI to double check to IO_IF_SEL bit, it can the bit from 1 to 0 by sending 0XF0F8FC and time- based pattern
