This display uses the ST7066 Controller which is very similar to the very common HD44780 controller.
first google hit on the data sheet https://www.sparkfun.com/datasheets/LCD/st7066.pdf
I found several github references with code samples and even sparkfun has sample code
https://www.sparkfun.com/products/9053

the ST7066 ships in either a 5 V or a 3.3 V chipset.
the only thing to be concerned with is whether the LCD is actually a 3.3 V device.  If it is a 5 V device, it may or may not work at all.

I am using the 16x2 WH1602A display. For the communication I use the GPIO ports with the functions of "gpio_18xx_43xx.h" library  to send bits to the LCD . Thanks! :bigsmile:

Hi MC1992,
Could you please let us know the details of LCD? What interface is used to communicate with LCD? SPI ?
