TIDA-060024： Set the communication command of the ultrasonic sensor

Hi Jerry,

Please refer to the PGA460 Software Development Guide (Rev. A) and PGA460 Energia Library and Code Example (Version 1.1.0) (Rev. J) for guidance and examples on using an MCU-UART with the PGA460.

To UART will need be configured as follows (from the PGA460 datasheet):

The UART asynchronous-mode interface in PGA460-Q1 is designed for data-rates from 2400-bps to 115200-bps operation, where the data rate is automatically detected based on the sync field produced by the master controller. Other parameters related to the operation of the UART interface include:

• Baud rate from 2400 bps to 115 200 bps, auto-detected (as previously described)
• 8 data bits
• 1 start bit
• 2 stop bit
• No parity bit
• No flow control
• Interfield wait time (required for 1 stop bit)

Table 3 of the PGA460 datasheet shows you all available UART commands.
