I have a problem with an ESP32 devkit V1 card. I'm trying to connect a WG12864A Winstar mod graphics display via the I2C MCP23017 adapter (RobotDyn), using Nick Gammon's
Everything works well by connecting it to the Arduino Uno - Duemilanove board. Loading the sketch
LCD_Demo_Using_I2C present in the library is compiled correctly without errors.
If I connect the display to ESP32 devkit V1, I try to compile it I get the following error:
C: \ Users \ Topolino \ Documents \ Arduino \ libraries \ I2C_graphical_LCD_display-master / I2C_graphical_LCD_display.h: 62: 26: fatal error: avr / pgmspace.h : No such file or directory. Compilation terminated. exit status 1 Error during compilation for DOIT ESP32 DEVKIT V1 card.
I tried to compile it with PlatformIO presents the usual compilation error. You can help me, someone has some ideas to solve the problem.
