Just starting to test out Fs2020 after Karl‘s latest video. Wired up a Arduino mega with Max7219 and a encoder. All appears to work correctly (747 MCP - Heading display and adjustment) then for no reason, the 7 segment becomes corrupt , stops working and have to take a restart Of sim and Mobiflight.
anyone experienced this or know the reason why. Checked all connections. Re flashed arduino eprom and reloaded Mobiflight. Still getting the same issue, it works for a little while then corruption. Arduino is powered via 12v dc
