Is the SEN0628 8×8 serial protocol published anywhere?
Doug.Fajardo 2026-08-09 23:59:07 110 Views2 Replies I am trying to use the SEN0628 in Serial port mode. For a variety of reasons I can not use the DFRobot library (perhaps a separate subject).
When I connect 5v power, (The power light on the device is on), and look at the serial data lines with an oscilloscope (not connected to any processor), there is no data flowing (I was kinda hoping the device would just start running, but apparently not).
I suspect the device is waiting for some command(s) on the serial port to start working (e.g.: select 8x8mode?) - are these documented anywhere?
You can also check if the firmware has been burned in and if there are any issues with the update.
Jason.Miao If you can't use the library,use USB-C instead — the module outputs 8×8 data automatically over USB at 115200 baud with no initialization needed.
