USB_Host_Shield_Library_2.0 SPI issue in combination with TFT_eSPI #802

Open Paulsburg opened 5 months ago

Paulsburg commented 5 months ago

Hardware: esp32 dev kit Compiler: Arduino IDE 2.2.1

The acm_terminal example doesn't run together with the TFT_eSPI library.

If added some software lines to the example, to test the HostShield-Lib running together with the TFT_eSPI-Lib. Goal is to program a smart USB-terminal to observe the output of all of my esp32 applications without using my laptop. Only displaying the serial datastream, no inputs, no further controls as inputs.

Info:

What might be the problem? I am really helpless.

The used arduino sketch ist added to this issue as ZIP-file. At the end of the sketch I added the serial output for the two described cases. The other esp32 is producing incrementing textlines to test the behavior of the USB_Host_Shield_Lib. You can see them at the end of the serial output.

Here are some results of additional investigations on this issue: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Even if I separate the two SPI-members (no more both connected to the VSPI-bus)

Paulsburg commented 5 months ago

I am now asking the same question in Bodmers TFT_eSPI chat. To connect the two issues, Soon I will display here a link to Bodmers chat.

Paulsburg commented 5 months ago

Solution found, see the issue #3151 on TFT_eSPI. Just uncomment the use of the HSPI interface in the user_setup.h
