@gordsh thanks for sending, I actually don't know eez studio at all, I have never used it..

@mukul_100_ Here is a small demo of the M5Dial with touch and LVGL. Hope this helps and sorry for the delay.

M5DialLVGLTouchDemo.ino

@mukul_100_ I did get this working, I am having a different issue now but I will send you a small demo program that I wrote using LVGL with touch.

@felmue Thanks so much, that fixed it...

Hi Team:

I am getting the following error on an Arduino program that worked perfectly prior.

c:\Work\ArduinoV2\libraries\M5Dial\src\utility\MFRC522.cpp: In member function 'uint8_t MFRC522::PCD_CommunicateWithPICC(uint8_t, uint8_t, uint8_t, uint8_t, uint8_t, uint8_t*, uint8_t*, uint8_t, bool)':
c:\Work\ArduinoV2\libraries\M5Dial\src\utility\MFRC522.cpp:464:20: error: '_validBits' may be used uninitialized in this function [-Werror=maybe-uninitialized]
if (backLen < 2 || _validBits != 0) {
~^~~~~~
cc1plus.exe: some warnings being treated as errors*

I am using

Arduino IDE - C2.3.4
esp32 by Espressif Systems 3.1.1
M5Stack by M5Stack official 2.1.3

Any help/ideas?

@PharkieB Here you go

M5Dial v6.f3d

@PharkieB Here is one that I made a while back M5Dial.stl

OK, I figured this out. Turns out my Arduino [Partition Scheme] setting was incorrect. I had a setting of
[Default 4MB with spiffs (1.2MB APP/1.5mn SPIFFS]
instead of....
[8M with spiffs (3MB APP/1.5MB SPIFFs]

Now after the sketch upload, I get
Sketch uses 1265261 bytes (37%) of program storage space. Maximum is 3342336 bytes.

Programming the M5Dial with an Arduino sketch and getting the following message after successful programming:

"Sketch uses 1265041 bytes (96%) of program storage space. Maximum is 1310720 bytes."

This means that I only have 1.3MB of program space.....But the M5Dial has 8MB of Flash.

Is there any way to access the additional space for my sketch?

Hi Teastain, thanks for your response. We will try and create a model in Fusion 360 using the physical dimensions. Thanks for your help.

Hello, we are using the M5 Dial in a project to build a touch screen controller for an aircraft and need it to complete the modeling in Fusion 360 of the electronic and hardware design

Does anyone have a 3D file of the M5 Dial?

Thanks

@felmue, thanks very much, This worked perfectly.

M5

Thank you.

Can any one get this simple GC9A01 test to run on the M5Dial

• https://github.com/carlfriess/GC9A01_demo

My goal is to have LVGL running on the M5Dial so I am working my way through the display issues at this time.

@ajb2k3 said in M5Dial TFT_eSPI pinout:

GC9A01 driver

Hmm, no I did not. Let me do some research and try to find the driver

Does anyone know the correct pin assignment for the M5Dial SPI bus? I am trying to run LVGL with TFT_eSPI. I have tried the pin assignments I obtained from the M5Dial specifications page but I am having no luck. Here is what I have so far

// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins

#define TFT_MOSI 5 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 6
#define TFT_CS 7 // Chip select control pin
#define TFT_DC 4 // Data Command control pin
#define TFT_RST 8 // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL 9 // LED back-light

I am trying to run LVGL on the M5Dial using Arduino and LovyanGFX. Does anyone have any examples?
