#ifdef HAL_ESP32_HAL_H_

[AugustQu]

with the latest update of PlatformIO I was no longer able to compile the code. The problem was the statement
#ifdef HAL_ESP32_HAL_H_
in the file OneBitDisplay.cpp.

This is te error-message:

Compiling .pio/build/usb/lib0c7/OneBitDisplay/OneBitDisplay.cpp.o
.pio/libdeps/usb/OneBitDisplay/src/OneBitDisplay.cpp:51:23: fatal error: BLEDevice.h: No such file or directory

I had to undefine it explicitly. Then it compiles and the code worked.

I rolled back OneBitDisplay to v1.5.0, this should work.
Besides this issue i discovered a pixel display bug in current OneBitDisplay v1.7.1, so it's better to avoid this version.

With v1.5.0 it does not work either for me.

.pio/libdeps/usb/OneBitDisplay@1.5.0/src/OneBitDisplay.cpp:47:23: fatal error: BLEDevice.h: No such file or directory

I had to undefine it explicitly. Then it compiles and the code worked.

Sorry for my beginner question: How did you do this and where can I find this file?

[cyberman54]

Please post platformio version and platform (Win/Linux).

Core 5.0.0·Home 3.3.0 on macOS

[cyberman54]

allright, i never tested pio 5.0.0, still sticking to 4.3.4

[vrees]

I can confim to this issue using following config:
PlatformIO: Core 5.0.0, Home 3.3.0
Linux, T-Beam
ESP-IDF v4.3-dev-907-g6c17e3a64-dirty

As workaround I tried following statement in OneBitDisplay.cpp
#undef HAL_ESP32_HAL_H_
Which helps to get rid of compiler error but leads to crashes after deploying to T-Beam.

[cyberman54]

I tried to load ESP32 BLE library by adding a lib_deps statement in platformio.ini. Still compiler error with OneBitDisplay. Checked, that the files (BLEDevice.h, etc.) are present in the .pio build environment, and yes, they are.

Weird. Can anyone help?

I can also confirm on:
PlatformIO: Core 5.0.0 Home 3.3.0
Windows, T-Beam v10

I got the code now compiling by modifing the file <project-roo>\.pio\libdeps\usb\OneBitDisplay\library.properties (OneBitDisplay library) by commenting or deleting the line depends=BitBang_I2C:

(Do not forget to press "Clear" before rebuilding or delete .pio\build\usb manually)

name=OneBitDisplay
version=1.5.0
author=Larry Bank
maintainer=Larry Bank
sentence=OLED and LCD library for 1-bit per pixel displays.
paragraph=Designed to provide a rich set of features with a simple API. Can automatically detect the display address (3C or 3D) and the controller type (SSD1306, SH1106 or SH1107). Includes 4 sizes of fixed fonts (6x8, 8x8, 16x16, 16x32). Can use I2C, SPI or bit bang I2C+SPI on any GPIO pins with the use of my BitBang_I2C library. Supports display sizes of: 128x128, 128x64, 128x32, 64x32, 96x16, 72x40. Includes scrolling text/gfx, deferred rendering, lines, sprites, circles, rectangles and a simple menu system.

includes=OneBitDisplay.h
;depends=BitBang_I2C

Maybe this information helps somehow?

@pbriesch
the compiler complained about an include in the file OneBitDisplay.cpp. So I added some lines:

#include <SPI.h>

#ifdef HAL_ESP32_HAL_H_ // added
#undef HAL_ESP32_HAL_H_ // added
#endif // added

#ifdef HAL_ESP32_HAL_H_

The lines I added are between the include and the ifdef. Simply said: I undefd this define. Then it compiled and the code worked for me.

My environment:
Visual Studio 1.48.2
PlatformIO: 5.0.0 Home 3.3.0
Ubuntu 18.04

@AugustQu

Thanks, is working now!

As described in my workaround there is a difference when building:

Without the depends in library.properties platformio recognizes that OneBitDisplay lib depends on "ESP32 BLE Arduino"

|-- 1.5.0 (E:\ESP32-Paxcounter.pio\libdeps\usb\OneBitDisplay)
| |-- <BitBang_I2C> 2.1.1 (ESP32-Paxcounter.pio\libdeps\usb\BitBang_I2C@2.1.1)
| | |-- 1.0.1 (C:\Users\user\.platformio\packages\framework-arduinoespressif32\libraries\Wire)
| |-- 1.0.1 (C:\Users\user\.platformio\packages\framework-arduinoespressif32\libraries\BLE)
|-- 1.0 (C:\Users\user\.platformio\packages\framework-arduinoespressif32\libraries\SPI)

Without that change platformio fails to recognize the dependecy and does not add "ESP32 BLE Arduino"

|-- 1.5.0 (E:\ESP32-Paxcounter.pio\libdeps\usb\OneBitDisplay)
| |-- <BitBang_I2C> 2.1.1 (E:\ESP32-Paxcounter.pio\libdeps\usb\BitBang_I2C@2.1.1)
| | |-- 1.0.1 (C:\Users\user\.platformio\packages\framework-arduinoespressif32\libraries\Wire)
| |-- 1.0 (C:\Users\user\.platformio\packages\framework-arduinoespressif32\libraries\SPI)

[nordominus]

Okay, somehow the Library Dependency Finder (LDF) of Platform.io misses to detect the dependencies of OneBitDisplay.

Add "lib_ldf_mode = deep" to your platformio.ini in the [env] section, like this

Clean (or delete whole .pio folder), build again and it should compile now

Thanks for investigation and fixing! Tested & Merged.
