Hi Xinbai,

I tested both the default pins in the app-shield-LCD program and the ones you listed and the LCD seemed to be working well. Please make sure your mbed library and the Seeed Arch BLE firmware are updated to the latest version.

If you're still having issues, please publish your code so I can take a look.

All the best, Brian

Hi Brian,

Thanks for your kindly support, I found the bug in my code and know why I am wrong. I should use P17 as A0 pin, but replaced it with P14 when coding since did not find the P17 in Pinout picture of Seeed Arch BLE. http://developer.mbed.org/platforms/Seeed-Arch-BLE/

Anyway, use DXX but pxx should be a better way, thanks again.

Best Regards, Xinbai
