FireBeetle Covers ePaper Black&White only works in Arduino IDE and not in PlatformIO

I work on a project with a Firebeetle ESP32 and the E-Ink display in PlatformIO and somehow the display renders objects and lines but not text when I compile the example code from https://wiki.dfrobot.com/FireBeetle_Cov ... 1#target_4 in PlatformIO. When I compile the same code in Arduino IDE shapes, lines AND TEXT get displayed as it should. I've included the same libraries. The output from PlatformIO is as follows:

The code looks as follows:

Here is a look at my platformio.ini flie:
Code: Select all
; PlatformIO Project Configuration File ; ; Build options: build flags, source filter ; Upload options: custom upload port, speed and extra flags ; Library options: dependencies, extra library storages ; Advanced options: extra scripting ; ; Please visit documentation for the other options and examples ; https://docs.platformio.org/page/projectconf.html [env:firebeetle32] platform = espressif32 board = firebeetle32 framework = arduino upload_port = COM9 monitor_port = COM9 monitor_speed = 115200 lib_deps = Tiny BME280

Any ideas why the text gets only rendered when compiled with Arduino IDE and not in PlatformIO

2020-06-26 05:25:43 Thanks Christophe and Nana

The commenting of the "supportChineseFont();" line does the trick for me since I don't plan on using chinese font any time soon

. Thanks for sharing your insights with me. oli.gafner28

2020-06-13 17:28:30 Hello,

I have exactly the same problem with PlateformIO, the texts are not displayed. Same configuration as Oli and same sources. I found a solution by commenting the line "supportChinesFont ()" on the class DFRobot_IL3895_SPI :: disStringIL3895SPI

void DFRobot_IL3895_SPI::disStringIL3895SPI(uint8_t x, uint8_t y, uint8_t size, char *ch, uint8_t color)
{
DFR_W21_CS_1;
GT30L_setCSPin(DFR_GT30_CS);
setTextSize(size);
//supportChineseFont();
setTextColor(color);
setCursor(x,y);
print(ch);
}
