10.3.4.3 Addressing a heater controller
To address a heater controller, use the following structure:
DEV:<UID>:HTR
Where <UID> is a unique identifier that is allocated to each board, based on its SPI
location.
The configuration settings for a heater controller are:
The signals for a heater controller are:
