Where is the BOOT button on the T-Embed please? #110

Closed reflectingme closed 1 year ago

reflectingme commented 1 year ago

Have one of each of T-Display, the Touch version and the T-Embed versions. Excellent boards.

However, I am aware there is a TIP listed on the T-Display GitHub page to reset the T-Display and Touch versions by holding down the BOOT button while connecting the USB, then releasing and re uploading the code etc... Unfortunately I appear to have a non working T-Embed device and I want to do the same procedure but can't see where any BOOT button is located on the board, or how I do this boot type reset on the T-Embed device.

Could someone please let me know the similar procedure as to how I get the T-Embed device to reboot using the holding down the boot button method please?

Yep, I have seen that page and I see there is a reference to 'Boot' in one of the diagrams towards the bottom of the page, but there is no actual physical boot button that I can see on the board that would allow me to press it whilst connecting the USB cable to start that process!!

As this is the T-display, i just thought a comment in the embed section may gain a response from people who have the T-Embed. Here, most just have the T-display.

Apparently the BOOT button on the T-Embed is the encoder button, but when I try the same process by holding down the encoder button, it still does not do the full re-boot process. It appears I may have a dead display on my T-Embed sadly.

Hold boot pressed, Press and release reset button, then release the boot button. Don't give up on your display...TTgo/lillygo have poor support. Put me off using these in commercial products. Good to play with though.

So when do I actually do this please...? When in this series of button presses do I connect the USB serial cable...?

And yes, I agree with you 100% - I really do like the boards, but support is sorely lacking. My sincere thanks goes out to good folk such as you for helping as you do. Cheers... I owe you a pint :)

I've tried doing as you suggest but I reckon I received a dead display. Code appears to compile and upload successfully, the LED's do some stuff, but the display sadly, remains as dead as a Dodo!!!

Did you raise an Issue over at the T-Embed GitHub repository ? I do not have a T-Embed to test…but a common problem with the LilyGO T-Display S3 is the TFT_eSPI library must be the EXACT one supplied for your model of LilyGO and not the latest Bodmer and certainly NOT the one supplied by Arduino OR doing a “Arduino Library Update"

Hi Terry

Yep I did raise an issue on the GitHug repo, and many thanks for the specific pointer re the TFT_eSPI library. I will clone the entire repository and attempt to get it working using that. Thanks for the pointers.

T-Embed dT-Embed's BOOT button is located in the middle of the rotary encoder. Sorry, this reply is a little late. I hope you have solved this problem

Thanks Lewis, I have managed to resolve the issue but it wasn't due to the BOOT button reset process, it was down to the T-Embed display drivers and the TFT_eSPI library - which if used with this board, required a specific TFT_eSPI library available on the T-Embed LilyGo GotHub pages, and NOT the one generally available library from Bodmer.
