Hello,
Is it possible to control a MAX7219 LED-driver by Oshonsoft code? The serial communication to a MAX7219 is not 100% compatible to SPI.
The MAX7219 is communicating by folowing ports:
-DIN
-CLK
CS will not be used at the MAX7219, so for the selection of the chip LOAD must be high i think?
Is it true that i don't have to use slave adresses? I want to use two drivers and each driver has it's own function.
With normal SPI you'll give a slaveadress, but is it correct that i only have to make the LOAD-input high at the driver i want to write to?
Does anyone have a working example for this kind of communication?
(I know that the MAX7221 if fully compatible to SPI, but i bought by mismatch 10pcs of MAX7219 chips and they are not cheap)
Thank you!
