microcontroller using Nuvoton and lm35

Hello, anyone here know how to use Nuvoton NUC 140 VE3CN? I get some trouble on connecting the pin and using what kind of library to activate the pin. We already success in compose the main.c but the data can not show in the LCD. I got text like this:

warning: unknown conversion type character 0x20 in format [-Wformat=]

Thank you in advance
