STM32-SDI12

Its a SDI-12 library for STM32 microcontrollers.

Method

Single UART/IO pin is toggled between RX and TX. Compatible pins will depend on the STM32 microcontroller you are using.

Tested on

• STM32L476RG (not 5V tolerant! level shifter is required)
• STM32L073RZ (5V tolerant on pin PA9) by @dajtxx

Supports

Where a or b is a devices address and n is a stored data index.

• Acknowledge active (a!)
• Send identification (aI!)
• Change address (aAb!)
• Start measurement (aM!)
• Send data (aDn!) where n = 0 to 9
• Start verification (aV!)
• Start concurrent measurement (aC!)
