Hi John,
While I don't have any experience with the Armmite's SPI interface, I suspect it is very similar to other 'Mites in the family.
I have used the SPI instructions in MMBASIC to communicate between a Micromite Explore 28 or a Micromite Plus Explore 100 and a variety of ADC, DAC, Load Cell, or PIC16F microprocessor chips reliably. While some claim to have an SPI interface, they may be better described as "SPI like" in a lot of cases.
I have found that talking to a Microchip MCP3204 ADC for instance, requires MMBASIC Mode 0 :-
SPI open 30000,0,32 ' 30KHz, Mode 0, 32 bits.
but for a PIC16F1776 with the SPI peripheral CKE and CKP both = "0", MMBASIC Mode 1 is required :-
SPI open 30000,1,8 ' 30KHz, Mode 1, 8 bits.
I hope this may help rather than confuse !
With best regards, Paul.
