Note: SEGn p-channel, open drain output, GRIDn N-channel, open drain output. when using, SEGn connect to anode of LED, GRIDn connect to cathode of LED. 4.5、The serial data transfer in the applications 4.5.1、Address Increasing Mode
Display memory is updated by incrementing addresses. Please refer to the following diagram.
where:
Command 1: Data setting command Command 2: Address setting command
Data 1 to n: Transfer display data (16 bytes max.)
Command 3: Display control command 4.5.2、Fixing Address
The following diagram shows the waveforms when updating specific addresses.
where:
Command 1： Data setting command Command 2： Address setting command Data 1 : display data Command 3：Address setting command Data 2 : display data
