I've been playing with the new brightness controls this week on my MAX7219 controlled 7-segment displays. This seems to work pretty well and it got me to thinking about how I could add brightness control to my DM13A controlled LED indicators.
Presently, I've built my NAV/COM module with 4x7219 controlled 7-segment displays all connected through a output multiplexer (74HC4067). The module also has a DM13A for several LEDs I have on the module. Instead of bringing in an additional PWM control wire for the DM13A brightness control, I was wondering if I could add a MAX7219 matrix to the multiplexer to drive the LEDs? The advantage would be conserving the PWM control wire and removing the control wire necessary for the DM13A.
Looking through the configurator, it doesn't appear that this is supported today. Maybe consider this for a future release?
