max7219 8 digits 7 segment display

Thanks Ben,

Yes - I used pin 10 as CS - but still sometimes nothing in hardware mode

For fun - I added a SlideIn(str) - which slides in a string (it's a number but can also have - E,H, P, L or a space - note that the decimal point needs to be preceded by a digit) - I'm still just using the BCD display. This means it can 'slide in' HELLO... (0 slides in then L then L etc.)

Then I added a DHT22 and I 'SlideIn' the temperature and humidity on a 5s cycle. I was tempted to add a DS3231 and add the time too.

I modified DispNumberStr to be able to display the string at any position - so a scroll in would be easy... DispDigitBCD now takes an ASCII char (0..9,-,E,H,P,L or ' ')

Any one any ideas - there a lot less fun transitions (probably) - but I thought a SlideOut would be good too?

Just had a flash of inspiration - and hardware SPI is up and running.

I just added a Master_Disable_CS before the Master_Init and away it went. Odd - I always thought that using b2 as the CS pin was sufficient.

Aha well done, yes that is suprising but good to know.

I can maybe add that into the SPI CAL component so it does that for you before initialising the SPI.
