STM8S Discovery firmware - LCD display pinout

Hello

I'm trying to connect LCD display (WH1601A) to the demo board and use firmware SPI module and SPI_SimplexLCD example as base of my code.

But I can't see which PINs (ports) I should use to connect LCD display or where I can select MCU port. I found only ChipSelect and Backlight PINs configuration code (in

https://my.st.com//public/STe2ecommunities/mcu/Lists/STM8SDiscovery/mono__lcd_8h.html

). Could you please help me configure data port of say which port was used in sample program?

Thanks

Dmitry

Hi, Dmitry!

File mono_lcd.c is part firmwire for demoboard STM8/128-EVAL, LCD use on this board have SPI interfice, as connect this GLCD may see on schematic board (doc UM0842 - 

http://www.st.com/mcu/familiesdocs-113.html

). 

But why SPI? WH1601A not work in SPI mode.

I use 4-bit mode for WH1602 on my STM8S-Discovery and no problems.

Petr.

Petr,

Thanks for you answer! I'm novice in MCU programming and firmware would help me with my experiments. I found couple libraries which work with LCD but was thinking firmware using is better way. I found LCD management example which uses SPI and planned modify them a little.

But now I'm going to try with third-party libraries.

Hi, Dmitry!

If you new in world programming MCU, the fastest and simplest way (IMHO) to your case here

Petr,

I'm already trying with this example;)

Thanks
