I am new to the IoT arena but want to learn all I can. The hardware nomenclature is new but not completely foreign. I understand the concepts and I have no problem on the programming side of things. What I lack is knowledge concerning the pin assignments and the use of the library files in the device code (i.e. spi )
For my first project I would like to get a thermocouple connected to an imp004m using an Adafruit 31856 with a K type thermocouple. I found an old article on the Adafruit web site connecting a 31855 to an April board but I used it to get started.
I have been trying different combinations of pins using what little I can interpret from the Mux table for the imp004m, with no luck. I have verified the max board is getting power on my breadboard with my voltage meter so I know my pin assignments and/or device code need help.
I am attempting to use pinJ to get the reading. In my code and I initialize spi using the following, with parameters but I am uncertain about those also:
spi = hardware.spiGJKL;
BUT … I am not sure what pins the Chip Select maps to
imp004… MAX 31856 pin
pinJ … SD0 (MISO)
pin ? … CS (chip select)
AND I am not initializing pinK in the device code … pretty sure I need help there too.
Any and all help is appreciated.
