ESP32_TFT_library on M5Stack

[vibnwis]

Hi there,
I am running ESP32_TFT_library tft_demo.c on M5Stack. I managed to compile without any errors and flashed to M5Stack. Also, makefs. However, the M5Stack does not display anything, but blank. What is going wrong? what display type should I set? It is the default type, DEFAULT_DISP_TYPE DISP_TYPE_ILI9341. Very appreciate your response. Thank you

Resolved.
In make menuconfig, users need to set M5Stack under TFT Display DEMO Configuration --->

[vibnwis]

However, the demo is running now except image display are blank. Had anyone the similar experience?

[fly135]

I'm using the same library with the WROVER board and the demo seems to work fine. For some reason when I use it in my program I can draw lines but the screen clear doesn't work.

The image display has been resolved. It was due to multiple reasons:
1. The required images need to be uploaded separately. Read the given instructions.
2. The setting of the image partition in Make menuconfig is wrong. See the corrected value, https://github.com/loboris/ESP32_TFT_library/issues/24
3. The source code does not actually show all the images. It shows only one. Hence, if you need to see all of them, you will need to modify the source code.

Hope these help.
