@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.

@sasetcolombia You need to use unused IO pins. For example the IO2、15、18、19....... This can be seen in the schematic diagram

To achieve this function, it needs to be implemented in software to rearrange the pixel arrangement. Or you can use lvgl, for screen rotation.

Please use this app to test. https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/examples/SleepTest

@jimh
Hello, pins above 34IO can only be used as input

@tcccorp 1. To set the local SMS center: AT+CSCA=""+ Press Enter, return OK. For details, consult your carrier.
2. AT+CMGF=1: Set the SMS mode to TEXT.
3.AT+CMGS="phone number"< enter >, set the receiver phone number, then return: ">",
Send desired content, such as "Send Massage Test!" You don't need a carriage return at the end,
After editing the SMS message, send the message in hexadecimal format 1A (1A is the key value of CTRL+Z, which tells the module to send the message.
You can also send 1B, that is, "ESC" to cancel the operation.) After the sending is successful, the module returns +CMGS: 15 to confirm the successful sending.

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

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

You mean put the watch on the table, touch the panel and it will move by itself?
You can try to write TouchPad Example into the watch, then put it on the desktop without touching it, and check whether the coordinates on the screen will change. If it changes by itself, please contact customer service for after-sales processing.

Is the driver for CH340 installed? Is the correct baud rate used?

@winfried Hi. You can use the 3.7V battery in your picture to power the T-display, note the +, — signs.

@gandalf Hi. The USB port has no detection circuit design.

@yu Hi. The test range requires one transmission and one reception to perform the range test, and care should be taken to choose an open and unobstructed place. The sender can be placed in a high place if allowed.

@jezerca said in 10000 mAh Li-Po battery with TTGO T-Call&PMU SIM800L ?:

Hi all,
Expect the long charging time, would there any problem to use such kind of battery? Does the AXP192 board support it?

Hi. You can use this 3.7V battery, the default charging current is 500ma, you can modify it by programming.
