MuIn LCD + firmware
Does exist new firmware for that MuIn is not slow ?
Thanks in advance.
The MuIn firmware isn't slow, the response to the received characters is immediate, practically less than the time required to transmit a character at 57600 bps.
The response time to commands is a few microseconds to which is added time to run the command from the controller of the display that in some cases, such as clear screen, can take few tens of milliseconds, the mean time tipically is 2-3 ms, refer to data sheet of the standard Hitachi controller.
I'm investigating the issue of delay Arduino, proving MuIn LCD with PC or other microprocessor cards there is no slowdown.
