@papbo What is your current ESP32 version? Try upgrading?

@fdaher 👍

See https://community.lilygo.cc/topic/30/can-t-download-firmware-on-sim7600g-most-of-the-time for detail.

@yakuzja There are two ways to get started quickly

Use the Arduino IDE and install the ESP32 support package. Use the VSCODE PIO plug-in, this plug-in can automatically configure the environment for you, the compilation speed is relatively fast, and it also supports Arduino functions and libraries

Yes, crystal burrs cause the problem.It has now been fixed in the latest version

The schematic is here

@scheeri It can be connected to 5v, but after connecting to 5v, you cannot plug in USB at the same time.

@caz that's great , if you have any other questions in use, please feel free to contact us.

D1 and D2 pins are I2C

@gfaman said in T5 4.7 e-paper missing library::

hal/rmt_ll.h:

hey, I just had the same problem. just comment this header, and everything will compile correctly.
arduino already have these headers.

@ajlenze Only ESP32 can be found in the Arduino Boards Manager. You need to install ESP32. And C3 is a derivative of ESP32. After installing ESP32, you can select the C3 subclass chip in the board

@Customer-Support Hey would you please help me out with my post? I have posted in Technical Support about the LilyGo Tcall SIM800L 🙂

@Lilygo Hey could you please respond to my problem in thetechnical discussion page about location problems on the LilyGo T-Call SIM800?

@marmou Good job. You are awesome👍

@lilygo Thank you. I successfully build, download and run all example sketches.

Hello @dabee , Is the new battery suitable for the product ? If still have any other questions, please contact us without hesitation .

@joter Sorry. T3 is not using Espressif driver, but using ch9102 driver chip. I now send you the driver link of win10

The role of the blue font is to download

The factory firmware uses MY-TTGO-WATCH firmware, the original firmware offset touch coordinates is too large, you can refresh the firmware in TTGO_TWatch_Library , it should work fine, if you want to recompile the firmware, you can change the scaling here My-TTGO-Watch

@bocam
T-micro32 integrates ESP32-PICO-D4 chip inside. So choose ESP32-PICO-D4 when you choose.

Hello, the code has been fixed. The ESP32 Pico option is available.
