Have you tried the solution that worked for me?
You may need to define the pins used by SPI, something like
// Board Xiao ESP32-C3 crashes if pins are not specified.
SPI.begin(8, 9, 10); // SCK MISO MOSI
The multiple ESP32 variants and their implementations are rather tricky.
Thanks. I saw your post but have not tried that. What you showed didn’t look like a complete sketch,
just some lines of code.
For example, which libraries are needed in order to run it?
-R
That’s great that you got it working. But, you didn’t say which MCU board you used?
A few more details would help others solve this puzzle.
By the way, the board i used was the XIAO ESP32C3.
After starting my Arduino library from scratch i was able to get the provided demo to work. I have since added dome additional code to blank the screen and display the date and digital time.
like this on , NTP ?

Thanks. It seems that people using the ESP32 boards got it working.
I haven’t heard from anyone who was successful using a SAMD21 board though.
I’m trying to get something very basic working with the TFT_eSPI library.
I did verify the pinouts (in User_Setups/Setup66_XIAO_Round_Expansion.h) and they seem to
be correct.
So far no luck.
The Round display just shows garbage pixels and doesn’t draw anything.
Unfortunately, it has been a very long time ago and I should start again from scratch investigating those libraries with the Xiao round display.
Hi there,
I think it’s just not going to fit? or the pins are off or inverted or ? total guess here I don’t have a samd21 they have always been too light weight for my prototypes any way ,You may look at this link ,
SAMD21 (arduino mkr zero) with TFT 3.5 ili9486 albeit not directly about round eye display, but
worthy of a look imho, what frequency is your spi or clock?
GL PJ
Thanks, good point about the SPI freq. I didn’t set it but somewhere in the header files it is set to something. I’ll take another look.
-R
I’m sorry I’m late. From the error message you provided, it seems that you are correct, and this is most likely due to the Insufficient Memory error that pops up with XIAO SAMD21 running LVGL. In fact, the XIAO SAMD is quite an ancient being with only 32KB of SRAM and 256KB of Flash, which means that it is not capable of carrying LVGL animations with a certain volume (including the XIAO nRF52840 as well). So, I would recommend you to use it to complete some simple image display based on TFT graphics library.
You are right, that the SAMD21 has 256k flash and 32k sram.
The ESP32C3 has 4mb flash and 400k sram, I believe.
Not surprisingly, I wasn’t able to compile Seeed’s basic demo of the Round Display due to insufficient RAM on the
SAMD21 XIAO board.
But, a different demo (tft_espi-base-dial) only uses TFT_eSPI library, and it fit in RAM no problem.
However, it still did not work!
I believe I followed all the configurations suggested in Seeed’s Getting Started guide:
-R
Hi there,
So the Round Display is working Here; Xiao ESP32S3 in the Seat
Using library TFT_eSPI at version 2.5.23 (setup/selects with all edits)The Touch Screen warning NAG is present but it still connects to my WiFi, Then gets IP address and updates the Time from NTP server then Displays the “ROLO” tweaked Watch face.

I’m using the supplied versions of libraries from SEEED, not the ones the library manager would install. I’ve edited the <User_Setup_Select.h> as required:
// #include <User_Setup.h> // Default setup is root library folder
#include <User_Setups/Setup66_Seeed_XIAO_Round.h> // Setup file for Seeed XIAO with GC9A01 240x240
Still, no joy.
Has anyone actually gotten these Round Displays to work with the XIAO ESP32C3??
What’s the secret?
Hi there,
Are you using the BSP 2.0.8 try it with that and it should work.
HTH

You’re close so not to far to go. 
That was it! I was using espressif BSP 2.0.17. It turns out that only v2.0.8 will work with these displays.
Thank you for the final piece of the puzzle. The Xiao wiki really needs to get updated with this specific information.
Thanks again @PJ_Glasso

Wow,
What a mess this thing is… I need to talk to Seeed about returning some of the units I got…
its not worth the shipping cost… just give away to some kid to use as a science fair project
the eyeball sketch makes a good halloween decoration… quickly get them working and you can sell for 4x your cost… hurry up you got 15 days left

Hi there,
I must have a good mojo or smthing, I have NEVER received a NON-working product from Seeed Studio
Notice I didn’t use the work “BAD” 
Hardware is always good… Software it’s a WIP
