GLCD ST7735S Bitmaps

[jay_dee]

Hi, I've been asked to investiagte display options on a tiny graphic display, size wise the unit need to be less than 15mm in height. So I'm looking at 0.96" 160x80 pixel displays like,
https://learn.adafruit.com/adafruit-min ... 0-breakout
Which uses the ST7735S driver.

What are the options for displaying a bitmap logo on such a device? I did not see the bitmap option like there is for some of the other FC components.

If it is simplier I may just change to an alternate driver chip and associated FC component.
I would like to keep the update fairly nippy... say 10Hz?
I could use a Pi PICO but If I can get away with a robust PIC18F @ 20MHz that would be great.

Pretty new to Graphics, I have only done a bit with the 240x240 TFT ST7789 display from Adafruit, got most things working but Graphic displays are not my speciality!

Hello.
If you look in Component Library > Displays > Graphical Library section you will see two components for bitmaps.

GLCD Bitmap Draw FAT: Load bitmaps form a SD card.

GLCD Bitmap Draw ROM: Loads the bitmap from within the Microcontroller flash rom.
With the latter since the bitmap is stored on the microcontroller, you must make sure the microcontroller has enough ROM and RAM.
If it was me, I would compile to hex before even purchasing any microcontrollers.

For example projects, right click on the GLCD Bitmap component you are interested in, then select Help
