Hello, I'd like to write an LCD 2x16 (I'm working with LCD Keypad Shield, picture attached). It seems that LCD_Position() is not working.. when I print a string I just see the last character on first position (fw attached). Do you know what is the problem or an example with Psoc4 BLE + LCD?

Thank you.

Hello Fabri,

I programmed the CY8CKIT-042 BLE with your code without making any changes. It worked for me. Can you check if you have wired the board properly?

Pin connections:

P1.0 - D0 - LCD_Pin11

P1.1 - D1 - LCD_Pin12

P1.2 - D2 - LCD_Pin13

P1.3 - D3 - LCD_Pin14

P1.4 - Enable - LCD_Pin6

P1.5 - RS - LCD_Pin4 

P1.6 - RW - LCD_Pin5

You may have gone wrong in the highlighted pin connections, please check.

Regards,

Dheeraj

Hello Dheeraj,

thank you for your support. The connections were ok, so I found a single

display (without arduino shield, like you did) and It works! It seems that

the shield is connecting RW directly to GND.. this works for Arduino

library but not with Cypress library. Problem solved! Thanks again.

Regards,

Fabri
