Hi,
ESP32-WROOM-32UE has pins GPIO6-11 marked as NC, so it is impossible to connect an external PSRAM. Is there a way to migrate from ESP32-WROOM-32U to ESP32-WROOM-32UE (i.e. from v1 to v3) and to have an ability to use PSRAM?

Hi @Vader
As far as I know, the library supports only 24-bit BMPs, so BMP with alpha-channel will be ignored:
memcpy(&wtemp, buf+28, 2); // the number of bits per pixel
if (wtemp != 24) {err=-8; goto exit;}

It's interesting to hear from @loboris about plans on image transparency.

To put ILI9488 ...

I tested under latest esp-idf version with TFT ST7735 and it works fine. I added an issue to report minor changes on https://github.com/loboris/ESP32_TFT_library to compile with c++ projects. Thank you.

I have the fix for that issue ready, it will be pushed today or tomorrow.

Good news, and so fast.
In addition,
1) could you please change deprecated esp_heap_alloc_caps.h to esp_heap_caps.h and pvPortMallocCaps() to heap_caps_malloc()?
2) While experimenting with the TFT library I stumbled with ...

loboris,
the library does not print text by TFT_print() in esp-idf commits 845c3fb (22 sep 2017) and 050ae50 (08 sep 2017). Also there are some artefacts on screen. It looks like DMA transfer does not work correctly.

The esp-idf commit with which the library works fine is 5539bfb (07 aug 2017)

Building on on MacOS (Sierra) fails...

Got it, repository is updated, thank you.

On Linux the compilation fails on make makefatfs

Thank you for testing under linux. Now it should be ok. I've tested it on Ubuntu 16.04.3 x64.

Here is a tool to prepare FAT image on host and flash it to esp32.
https://github.com/jkearins/ESP32_mkfatfs

The tool is inspired by mkspiffs https://github.com/loboris/ESP32_spiffs_example tool created by loboris https://esp32.com/viewtopic.php?f=18&t=1901

Example of using FAT with ESP32 ...

But, I can't execute "make flashfs" and "make makefs"
Can you help me fix the error? Thank you!

Have you got environment variable OS? Run the command: What value will be shown on the screen?

Dear all，

I copied component.mk from https://github.com/loboris/ESP32_spiffs_example (components\mkspiffs\component.mk and components\spiffs_image\component.mk). But, I can't execute "make flashfs" and "make makefs" yet.
Who can help me? Thanks.

Did you try this receipt?
