Side button problems on UV380
Posted: Tue Mar 07, 2023 4:57 am
FYI.
The change i made to allow Row 1, 2 and 3 of the keypad to be scanned, seems to cause a problem on some UV380, so I have changed this to conditional compilation, so that only the DM-1701 is driving ROW 3 , High and Low
Colin thinks there is a problem with residual voltages due to the capacitance of the cable to the display + Keypad PCB , but unfortunately my UV380 does not seem to have this problem
Probably I need to unify the button and keypad scanning function, but I think there may still be a bug on the UV380 even if I made that change.
Does SK2 + # function on the DM-1701 ?
This is used in DMR mode to open the TG (Group Call) list
Thanks.
