rocketeer Posted January 15, 2022 Share Posted January 15, 2022 I figured how to use the MAX7219 to make the VHF, UHF and ILS work on the A10C. But the Tacan has the X/Y that needs a 14 segment display which the MAX7219 does not seem to be able to handle. What do you guys use to drive the 14 segment? Do they come in 0.36 or 0.4" size? The common 0.56" is too big for my taste. And please share the sketch as well for the type of driver board you use. Thanks.

agrasyuk Posted January 16, 2022 Share Posted January 16, 2022 for my UHF Radio I went with these : https://www.mouser.com/ProductDetail/Lite-On/LTP-3862G?qs=gnaPJ2cis70NSLLDN2qJAw%3D%3D I would have proffered common cathode model, but it is unfortunately out of sock. I cannot yet share a sketch. will be driving this as 8x16 LED matrix Anton. My pit build thread . Simple and cheap UFC project Link to comment Share on other sites More sharing options...
rocketeer Posted January 17, 2022 Author Share Posted January 17, 2022 thanks Agrasyuk. What will you be using to drive this 16 segment display? The Tacan needs a 14-16 segment to display the X/Y. The UHF seems to work fine with the normal 7 segment display or am I missing something? My A10C cockpit thread Link to comment Share on other sites More sharing options...
agrasyuk Posted January 18, 2022 Share Posted January 18, 2022 (edited) Actual ARC164 device while only displaying numerals still uses 14seg displays . I attempted to get closer to the real one I'm still exploring options on how to drive, for now busy with different item. PCB is designed to have transistor driving each of the common anodes. Connection header exposes the unit as 8x16 LED matrix. F Edited January 18, 2022 by agrasyuk Anton. My pit build thread .
