I try to connect three 40x2 display to MBHP_CORE_STM32F4 board in a MIDIbox NG controller.
The first two display are connected to J15A and J15B.
For third display i tried to recompile the MIDIbox NG application with following options in mios32_config.h for optional third Enable line (pin A6 of J5B):
#define MIOS32_BOARD_LCD_E3_PORT GPIOB
#define MIOS32_BOARD_LCD_E3_PIN GPIO_Pin_0
every time i get the same error

I use Eclipse for compiling.
I didn’t understand something. I’m not a coder.
In the CORE_LPC17 Module there was J28 for connecting other displays but not on MBHP_CORE_STM32F4 board.
I need some help.
Thanks all for your help and your time.
