PGA460: Communication interface for IO-Pin

Krzysztof Nawacki

Part Number: PGA460

Is it possible to communicate with PGA460 by IO-Pin interface using development board MSP‑EXP430F5529LP and PGA-460-Q1 EVM software?

If not how can I set IO-Pin communication for sensor and EVM software.

Hi Krzysztof,

The IO pin shares two communication modes. Depending on the bit setting of IO_IF_SEL, the mode will be dedicated to time-based interface or one-wire UART. The one-wire UART Interface is not fully supported by the GUI to process the return data. Only data transmitted in one-wire UART mode is supported by the GUI. The TCI mode is offered as an alternative, but it does not grant access to all of the device or GUI features. Section 3.5.3.2 of the PGA460 User’s Guide provides more info on this.

Instead of using the GUI for OWU or TCI, another option is to use the Energia code examples, The below app note provides more info on the software used in these code examples:
