Greg, You can check out the schematic on the associated GitHub Repo for details, but I am not using muxs or shift registers for the ZM1350 board. ESP32 --> PIC --> discrete transistor --> cathode pin.
That said, some of my previous designs have made extensive use of 7HC595s and 74141s Mahdi On Wed, Dec 4, 2019 at 5:02 PM 'Greg P' via neonixie-l < [email protected]> wrote: > Mahdi, > > Not multiplexed. > > Direct drive digits or segments are always on and not pulsed at high > speeds like in multiplexing.
