TT Go Watch V3 support #227

Closed valioiv closed 3 years ago

valioiv commented 3 years ago

What to change in the code in order to build it and run the firmware on V3 watch?

sharandac commented 3 years ago

I don't have a V3, but I tried to include it once. Please test it once. Don't forget to change the env to v3.

@sharandac, thanks for the fast reaction! I managed to build it with your new commit. Will flash it on the Watch once I receive my V3 device (hopefully on Friday this week). Will update you soon! Thanks again!

Hi @valioiv , @sharandac , I have compiled and tested your actual code with V3 device, and it throws exception because in TTGO TWatch Library 1.4.2 -> twatch2020_v3.h file the TWATCH_TFT_MISO constant is set to GPIO_NUM_MAX instead of 0: #define TWATCH_TFT_MISO (GPIO_NUM_MAX) (link)

The error itself (from serial port):

So, as long this bug is not fixed, you should disable DMA and double buffer in displayconfig.h

sharandac commented 3 years ago

as workaround, can you test the following addional build_flags in the ttgo-t-watch-v3 section in platformio.ini

build_flags = 
    -DCORE_DEBUG_LEVEL=3
        -D LILYGO_WATCH_2020_V3
        -D TWATCH_TFT_MISO=GPIO_NUM_0
    -mfix-esp32-psram-cache-issue
src_filter =

let's see if this works ... not pretty, but could work. apart from the warnings

titimoby commented 3 years ago

I'm both new to T-watch and platformIO but I tried both workarounds:

  1. platformio.ini modification suggested by @sharandac compiled but did not worked
  2. displayconfig.h modifications suggested by @PGNetHun worked, T-Watch is running.

I still don't know how to see serial port to verify I have same messages as @PGNetHun but without modifications or in case 1 the physical result is a T-watch with vibration motor on without interruption.

If I can help with tests, it's the max I can do for now, I need to learn quite a lot still.

PS: thanks for this project by the way 💖

sharandac commented 3 years ago

Thanks for you info. I have adapt it and disable DMA on V3 per default. Please test it and give me a feedback if will work or not.

PGNetHun commented 3 years ago

Hi @sharandac , Thank you for your quick fix, I can confirm, it works with V3! The previous solution (to add -D TWATCH_TFT_MISO=GPIO_NUM_0 build argument) was not working because the twatch2020_v3.h file has always overridden the TWATCH_TFT_MISO macro with GPIO_NUM_MAX. That's why it must be fixed in that repository: https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/issues/126#issue-866458449

@titimoby: to see the logs of ESP32, open the PlatformIO "Serial Monitor" window. So, if you are new to PlatformIO, you should do the following (see screenshot):

  1. After opening project, select the environment to build
  2. Run clean task (if you need to build project from scratch, for some build issues cleaning up build folder helps)
  3. Run build
  4. Upload built firmware
  5. Open serial monitor window: this connects to device via serial port with 115k default baudrate (configurable in platformio.ini)
  6. Any time you change code, repeat from step 3 (or step 2 if needed)

@sharandac, @PGNetHun, I can only confirm that TTGo Watch V3 is running fine with the following commit from the master branch (I've flash it a couple of days ago):
