Problem using IDF 4.4 with Arduino-Esp32 2.0.6 #7797

Closed HeadHodge closed 1 year ago

HeadHodge commented 1 year ago

Board

esp32-otg-usb-s3

Device Description

both usb-uart mini and usb-device type-a connected to usb connectors on my Win 10 laptop. usb-host type-a not connected

Hardware Configuration

out of box config

Version

v2.0.6

IDE Name

arduino ide

Operating System

win 10

Flash frequency

default board config

PSRAM enabled

no

Upload speed

Description

i'm using your cdm-acm-host example from esp32-idf v4.4 to create my supplied ported arduino code.

i was under the impression i could use the idf 4.4 library provided with arduino-esp32 2.0.6

but i cant get my ported example to compile. can't figure what the problem is. my 1st guess is i dont really have the idf 4.4 lib as advertised???

thanks for help

I have checked existing issues, online documentation and the Troubleshooting Guide

USB Host isn't supported in Arduino Core 2.0.6. The project compiles using IDF 4.4 header files (*.h), but it doesn't link. The static libraries of Arduino 2.0.6 do not have necessary code to link ELF file. That's why you are getting ld.exe error messages.

It may be possible to make it work using Arduino as IDF Component and then compile it as an IDF project instead.

USB Host isn't supported in Arduino Core 2.0.6.

Thanks for your reply. I'm confused... If USB Host not supported, why does this example work on my board? https://github.com/chegewara/EspTinyUSB/tree/master/examples/host/acm

Also from the esp32-arduino docs, what do the following lines in bold mean? I'm pretty sure idf 4.4 supports USB Host? Im probably confused by terminology.

The Arduino ESP32 version 2.0.6 based on the ESP-IDF v4.4.3 introduces bug fixes, improvements and new boards support.

Changes Here is a summary of the major changes.

ESP-IDF upgrade to v4.4.3 Support JTAG debugging in Arduino IDE 2.0 Esp Insights library support Improvements

Update ESP-IDF libs for 2.0.6 Support JTAG debugging in Arduino IDE 2.0

ESP32-S2 has hardware that supports USB Host mode. Arduino Core 2.0.6 doesn't support USB Host natively.

Chegewara's Library is independent, and it is his own implementation of USB Host CDC. I've never used it so far.

It means that Arduino Core 2.0.6 supports JTAG Hardware CDC driver which is present in ESP32-S3 and ESP32-C3 only. This is USB Device only, not a Host mode.

TinyUSB is an external library used by IDF can run as USB HOST and it works for ESP32-S2 and ESP32-S3 only. TinyUSB has both USB modes, Device and Host. Both are supported by IDF 4.4. BUT Arduino Core only has implemented the USB Device Mode, not the USB Host Mode yet.

Thanks again for reply.

my board is espressif esp32-s3-usb-otg. so you think i should be able to get a cdc-acm host working with esp32-arduino 2.0.6 and included tinyusb host support?

do you think an esp32-arduino version will come soon with better usb host support?

i love my otg-usb-s3 board and has everything i need except a working interface to my usb serial com (class 20) dongle connected my usb host type A on board connector

Yes, ESP32-S3 has native USB Host support in its hardware. It works fine with IDF framework. You can find IDF examples at https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host

There is an optional way to build Arduino projects that is called "Arduino as IDF Component". By using IDF 4.4 and Arduino, it is possible to use IDF USB Host API and Arduino API together. This option may require some expertise level, in case you want to try it.

I think that Chegewara's code can also be built using "Arduino as IDF Component" instead of using the Arduino IDE.

do you think an esp32-arduino version will come soon with better usb host support?

Yes, I think so. Maybe not so soon, unfortunately. We are currently working to release a new Arduino Core based on IDF 5.1.

From the IDF USB Host examples, you will find many ways to use it. https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host/cdc/cdc_acm_host
