When using V1 gain of 6 times, adjust the built-in electronic potentiometer so that V1 does not exceed 18 V. Electronic Potentiometer (2-byte command) This command is used for controlling the LCD drive voltage V1 output by the voltage adjustment circuit of the internal LCD power supply and for adjusting the intensity of the LCD display. This is a two-byte command consisting of the Electronic potentiometer mode set command and the Electronic potentiometer register set command, both of which should always be issued successively as a pair. Electronic potentiometer mode set (Write) When this command is issued, the electronic potentiometer register set command becomes effective. Once the electronic potentiometer mode is set, it is not possible to issue any command other than the Electronic potentiometer register set command. This condition is released after data has been set in the register using the Electronic potentiometer register set command. A0 DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 1 0 0 0 0 0 0 1 |
