ra8875 tft display quotation

ER-TFTM050-2 is 480x272 dots 5" color tft lcd module display with RA8875 controller board,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO,and ARM .It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.

It supports 8080 6800 8-bit,16-bit parallel,3-wire,4-wire,I2C serial spi interface. Built-in MicroSD card slot. It"s optional for 4-wire resistive touch panel (IC RA8875 built-in touch controller),capacitive touch panel with controller,font chip, flash chip and microsd card. We offer two types connection,one is pin header and the another is ZIF connector with flat cable.Mounting on board by default. There is no capacitive touch panel connection on the board of ER-TFTM50-2,its capacitive touch panel needs to be connected with your external board.Now we design another new board with capacitive touch connection named_ER-TFTM050A-2.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 5" TFT Touch Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

I"m running some initial tests with the RA8875 and 5" 800x480 screen. Everything works well except for when I try to load and use a different font. I"ve read through the forum and the internet and I"ve seen others with the same issue but I haven"t seen a solution.

From reading and looking at the source code I know that you cannot run in TextMode when you want to use a loaded font. TextMode works, as expected, when using the internal font. I"m not sure if perhaps the RA8875 needs the font in a different format or if the print calls are not working properly. I do know that the drawChar function works so that leads me to believe that issue lies in how the print calls are being used but I"m not a good enough programmer to try and debug this further. Here"s a section of my code with comments:

The RA8875 class inherits from the GFX class, which in turn inherits from the Print class. The Print class accepts a bunch of different kinds of arguments, and shuffles the data around to call a function named write() with a C string. The connections aren"t obvious though, and change in unexpected ways with the way the text is encoded.

only text sizes of 2 and 3 are successful in drawing the character on the screen. Sizes 0 and 1 don"t display anything but I think 0 or 1 did display a pixel or 2

I recall that there was an issue and PR (Pull Request) related to this since the RA8875 doesn"t natively support external fonts. I looked at github and found the issue is https://github.com/adafruit/Adafruit_RA8875/issues/29 and the related PR added this ability to make this work by using a compiler directive. Could you try adding the following directive to your code?

Working on a board that will drive at least 5 displays via 4-wire SPI from a Teensy 4.1. The displays have the RA8875 chipset. I"m more of a software guy than a hardware guy and could use application advice. I attached my starting schematic below, its missing pull resistors, caps, ect but show the basics. The goal of the project is to push different bitmaps to each of the screens based on button pushes. I have been reading up on Paul Stoffregen"s dive into the SPI implementation on the RA8875 and its bugs. Since I plan to add an SD card via SPI in the future it sounds like some extra work is required.
