Hey folks, I have recently bought a cloned 3.5" LCD screen for my Arduino project. I got it off Lazada.sg for only $8, so I kinda expected that it might be a little challenging to figure out the "How-Tos" on everything related to this shield.
I have been scouring the internet looking for ways to render stuff on the screen, and eventually, I found that MCUFriend is able to do that. But one thing that I am currently stuck with is changing the font type. The current MCUFriend library only allows me to change the font size on my display and not the type. I practically copied and paste the graphics test example and modified it from there. Also, I have considered using the Adafruit TFT & GFX library, but when I looked at the tutorial, I noticed something different. There is supposed to be a LCD_CD pin (Command/Data), but on my shield, I do not see it. Everything else seems the same, but on my shield, there is a pin called "LCD_RS". What is the function of the LCD_RS pin for?
(Above) This is the shield that I have. I believe some of you with a little more experience might be able to help me.
(Above) This is what I would like to achieve on my home automation project. You can see from the LCD that the fonts are just really small. Setting the font size to '2' makes it very ugly so that is the reason why I want to explore using different font types.
