NIOSII - Write output to Dev kit LCD

I am trying to switch over to eCos from MicroC/OS-II. I have succesfully installed eCos for NIOS 5.0. I have built and run the eCos hello example. I am now trying to modify the hello example ...

Hi,

Thanks for your prompt response.

I enabled the Hardware Serial Devices in ConfigTool.

I have also added the extra compiler CFLAGS options to my makefile:

-I'$(SOPC_KIT_NIOS2)'/components/altera_avalon_lcd_16207/inc -I$(PREFIX)/include/cyg/hal

I rebuilt the library and the LCD is now working for me.

Thanks!

P.S.

I added -I'$(SOPC_KIT_NIOS2)'/components/altera_avalon_pio/inc -I$(PREFIX)/include/cyg/hal

so I could use any of the PIO devices in my hardware. However, I get an undefined reference to IOWR_ALTERA_AVALON_PIO_DATA

when I tried to use it like shown below:

IOWR_ALTERA_AVALON_PIO_DATA(LED_PIO_BASE, 1); // turn on LED# 1

I am curious if the PIO devices have an enable/disable feature in the configtool too?
