Enable STM32 sequencer to complete other task during SDI-12 transmission #62

Open stevegtaylor opened 2 months ago

SDI-12 has a minimum delay of 28ms while the MC sends a 20ms "high" and 8ms "low" pulse to wake the sensors. This is a long delay and can be optimized by enabling the stm32 sequencer to complete other tasks during this delay.
