Re: Repeated USB MSC operation
Hi, I toyed with the MSD implementation a while ago and also had that experience. Do you get the expected uninstall messages when you unplug the device? That was what wasn’t working in my case. Somewhere deepdown a task is still running, I think, where it should have ended and deleted itself when un...

Re: USB Host not working on "ESP32-S3-USB-OTG Development Board"
I have the kit and it does work as host, and the usb-host-lib example should give you the USB descriptors of the device you’re connecting, from the looks of it. Did you route the the USB signals to the host connector and enable the power on it? Both need to be done for the ESP32 to function as host....

Re: ESP32-S3 USB host interface to keyboard
If you want to know more of the details required to write your own code for this, have a look the book “USB by example” by John Hyde. Amongst others it explains how HID devices work on a driver level, USB descriptor’s, HID reports etc. I used this years ago to write HID and other devices. Another wr...

Re: LVGL ESP32 Background colour for lv_label
If I remember correctly, it is something like that the text background is not opaque by default. Try setting the opacity to full, otherwise you’re indeed far more likely to get a response on the LVGL forum

Re: I2C reading problem - PCF85063A
Hi, On first glance, I see nothing wrong, so let’s see. Just to be sure; the waveforms suggest that external pull-up resistors are present on both lines as they should, is that correct? Then, I see that there is currently no error checking in the subroutines. I would like to suggest to have them dur...

Re: Eclipse build in subdirectory configuration
Ah right, "Working Directory", that was the name. I remember now... :D OK, pity that did not work, I hoped it would. Two possible other options: 1 There is an option to add cmake arguments under the "Build Settings". Cmake documentation says that the source path can be specified using "-S <path-to-s...

Re: Eclipse build in subdirectory configuration
I am not at my machine, so this is from memory. I think there is also a directory entry for the “start build in” or whatever it is called. That would (hopefully) be the directory eclipse would use to start the idfbuild.py command. I have not compiled any examples like this, so I am not sure, but the...

Another option could be LVGL: Light and Versatile Graphics Library. A generic library for graphics and touch controllers which is ported to a number of processors amongst which the esp32.

Re: What is the Recommended IDE for ESP-IDF ?
Bit of a lengthy answer, I know, bear with me. ;) Had a look at the logfile, and am noticing a few things. I know it seems like GIT has a problem (the null path) yet my guess is that this Is not the blocking issue, but that GIT is asked to perform an action on a non-existing path. I am not entirely ...

Re: What is the Recommended IDE for ESP-IDF ?
I am not sure which git version I have, yet I would be very surprised if that would be the cause of it all, I do not believe that.
