I can use rs232 to upload bitmap for GLK12232-25-SM, but can I2C support the upload? cause the datasheet said the upload process need negotiate between LCD module and MCU, but for I2C , how to support that ?
The I2C protocol communication is half-duplex

Hello Shen Li,

In theory, we should be able to support uploads in I2C but we have not actually tried it, and so we recommend that users upload their fonts and bitmaps in RS232 mode.

Thanks,
