#102828 - Shifting the cursor Responding to: ???'s previous message |
On the assumption that your LCD is controlled by the HD44780 or equivalent and you do not want to overwrite existing data with the cursor move. Obtain the current DDRAM address by doing a busy flag check. The HD44780 returns the address in the first six bits (7th is busy bit). Add your desired offset to this address and send it back to the LCD as a DDRAM Address Set Command by setting RS and R/W to 0 and bit 7 to 1 with the new address in bits 0-6.
