ttgo-lora32-v2: pins_arduino.h: missing

[peterus]

I am trying to compile my code for ttgo-lora32-v2, but it looks like there is an issue with a missing pins_arduino.h:

In file included from src/main.cpp:1:0:
/home/pbuchegger/.platformio/packages/framework-arduinoespressif32/cores/esp32/Arduino.h:185:26: fatal error: pins_arduino.h: No such file or directory

If i compile for ttgo-lora32-v1, it is working as expected but not for the ttgo-lora32-v2. If i take a look into ~/.platformio/packages/framework-arduinoespressif32/variants i can see that the folder is missing. After a deinstall and install of the framework, there is no change.

[jshank]

Confirming same issue for me. Selecting ttgo-lora32-v1 works but you then have to override the PIN definitions in code

#define OLED_SDA 4
#define OLED_SCL 15
#define OLED_RST 16

[valeros]

Looks like the variant for this board hasn't been released yet, so as a temporary workaround please use ttgo-lora32-v1 variant and the pin definitions provided by @jshank

[jshank]

Looks like something went wrong with the pull request for this board. It has the updated pins_arduino.h but ~/.platformio/packages/framework-arduinoespressif32/variants/ttgo-lora32-v2/variants/pins_arduino.h is still missing from the distribution as of 1.12.2.

[jon7sky]

I just noticed the same thing.

[jshank]

@valeros - Can you remove the board request label from this issue since the board has already been added, just not properly.

[peterus]

is there something I can do to have this faster available? I would need the pin definition for my next project.

[jshank]

@peterus just override the PIN definitions at the head of your file like I've shown above. I don't recall how many changes there were but you can reference pins_arduino.h for the correct definitions and redefine any pins you are using in your project.

#define OLED_SDA 4
#define OLED_SCL 15
#define OLED_RST 16

[peterus]

this is not a solution for me as i am sharing the project and a lot of people are depending on it. I could also overwrite the pin definitions directly in code, but this is also not nice if it can be done in the framework which is than working for everybody and every project in the future.

[owenschoppe]

+1 to get this board added correctly. Is there another repo we should be commenting on?

[SKRahulSK]

I am facing the same issue.
Please suggest if there is any update on this

[DenHerrRing]

My Solution for that:
Open [...]/.platformio\packages\framework-arduinoespressif32\variants
Create Folder ttgo-lora32-v2
Create File pins_arduino.h
Insert this:

#ifndef Pins_Arduino_h
#define Pins_Arduino_h

#include <stdint.h>

#define EXTERNAL_NUM_INTERRUPTS 16
#define NUM_DIGITAL_PINS        40
#define NUM_ANALOG_INPUTS       16

#define analogInputToDigitalPin(p)  (((p)<20)?(esp32_adc2gpio[(p)]):-1)
#define digitalPinToInterrupt(p)    (((p)<40)?(p):-1)
#define digitalPinHasPWM(p)         (p < 34)

[Bert-Tec]

I'm having this issue too

[dfsmith]

For my TTGO T3_V1.6 (supposedly a v2); the above with
static const uint8_t LED_BUILTIN = 25;

[chrisco484]

I'm having this same issue with a Wemos D1 R2 (Uno-like board, not mini).
