Unable to link emWin - missing LCD_IO_WriteReg

I'm trying to build a first graphical LCD project with Visual GDB (which lets you use Visual Studio for embedded development using the ARM GCC toolchain).

I can't find any sign of any of the LCD_IO_ routines in the HAL firmware (I've got the F1 stuff).  Perhaps its missing and Segger's stuff wasn't used for the demo on the 3210C, but from the presence of the STemWin_HelloWorld in the F1Cube firmware in Projects\STM3210C_EVAL\Applications\STemWin I have built this with IAR's EWARM, but I don't have the mapfile anymore to see where it got the functions from. I've got the ili9320 & 9325.c's added into the project, so there must be an SPI layer between these 2 files and the LCD. Segger defer to ST for first line support of emWin.   #segger-emwin-lcd-driver

Hi macfarlane.ken,

1- GPIO configuration is done in the file STM32Cube_FW_F1_V1.3.0\Drivers\BSP\STM3210C_EVAL2- Please refer to the 

http://www2.st.com/content/ccc/resource/technical/document/application_note/54/c9/95/42/8c/0b/43/69/DM00089670.pdf/files/DM00089670.pdf/jcr:content/translations/en.DM00089670.pdf

: it should help you to identify needed updates in order to use STemWin with HAL drivers.3- Please note that you may use 

http://www2.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-ides/sw4stm32.html

 as toolchain based on GCC. There is already a preconfigured project for this IDE: STM32Cube_FW_F1_V1.3.0\Projects\STM3210C_EVAL\Applications\STemWin\STemWin_HelloWorld\SW4STM32.-Mayla-

Thanks for your reply. I have  AN4323, but I don't think that the info that I needed was in there. I've got Helloworld to go on the F7 Disco board's LCD now, so I shan't bother any further with the F1.

However, I have more questions, but these are really on emWin, rather than the HAL or GPIO. Segger say that first line emWin support on STM32 is from ST, as the emWin trial version is FOC on the STM32. There doesn't appear to be an emWin support forum per se, so can I go off topic here & get answers?

Like most things here, it will be dependent on other users participating. The STM32 forum is the most trafficked.In a business sense, the from line support would be via your FAE.
