#190567 - Why not many MAX7219 drivers?
Responding to: ???'s previous message
Will the following idea be OK ?

1. I connect the segment displays in parallel for all 12 drivers and connect the header to the MCU port pins.
2. I connect the 12 nos CS pins of MAX7219 to 12 pins of MCU. Now I can send through SPI the required digit information to any of the 12 MAX7219 that I choose by controlling the CS line..
