Prerequisites
- PTN3460 Programming Guide
On Host PC
- LVDS panel's EDID config (128 bytes)
- (optional) one utility to edit EDID config
On RSB-3810 (Ubuntu)
- i2c-tools installed
sudo apt update
sudo apt install i2c-tools
(use EDID 6 and LVDS panel, G070VW01V0, as example below)
Convert EDID config to shell script
On RSB-3810 (Ubuntu)
EDIDNEW=6 # set EDID
EDIDBIN=g070vw01v0.bin
SCRIPT=~/set_new_edid.sh
REG81=$(printf "0x%02x" 0) # Please refer to the PTN3460 Programming Guide to set correct value
REG84=$(printf "0x%02x" $((2*EDIDNEW + 1)))
REG85=$(printf "0x%02x" $EDIDNEW)
echo -e "REG81:$REG81\nREG84:$REG84\nREG85:$REG85\n"
cat << EOT > $SCRIPT
#!/bin/bash
