7 inches Touch Display (eDP) for LattePanda 3 Delta, touch not working on win 10 IOT
Stephen.postlethwaite 2026-08-15 01:09:18 90 Views2 Replies Hi I have a 7" Touch Display (eDP) for LattePanda 3 (FIT0551) connected to a LattePanda 3 Delta / win 10 IOT Ent. The video is working OK, but the touch panel is not. It's all connected correctly, the FPC cable connected to the I2C touch panel on the LattePanda 3 Delta. Do I need a driver for the I2C touch?
Good catch on the BIOS update. It’s interesting that the display worked normally while the I2C touch panel didn’t respond, and the older 2023 BIOS turned out to be the cause. Glad you found the fix and shared the exact BIOS version for others using the LattePanda 3 Delta.
stephen.hanks Fixed, updated the BIOS to the latest , S70JR230-8G-A_20250416093826.bin
The BIOS was dated 2023
