Investigate low power uart peripherial for SDI-12 #72

Open jmadden173 opened 2 months ago

jmadden173 commented 2 months ago

Describe the Enhancement Switch implementation of hardware SDI-12 protocol from full USART to the LPUART to save power.

Benefits Power Savings

Possible Drawbacks Less functionality, maybe speed depending on the clock?

Additional Context When the hardware UART was configured, it was found that USART worked while LPUART didn't. There was also an option something along the lines of overflow protection that needed to be enabled/disabled. @stevegtaylor can provide more detail.
