I can read the ADC conversion for thermistor voltage in oscilloscope, but the LCD is not displaying the text and numbers.

Hi,

Did you set up the LCD properly ? Have you been able to display anything on LCD ? Kindly check any code example which uses LCD component to confirm what is going wrong at your end. The following appnote should be helpful.

The code example have LDC interface too. https://www.cypress.com/documentation/code-examples/ce210514-psoc-3-psoc-4-and-psoc-5lp-temperature-...
