False "Undefined" Errors

Hello. I am working with the STM32F334 DISCOVERY board. I found this example on the ST.com website. It compiles just fine in Keil uVision, but not here.

I ended up manually copying the many header and associated C files to correct these errors. Now I'm running into these errors which claim that the variables are "undefined". As you can see in my project at URL: https://developer.mbed.org/users/richardv/code/DMA_RAM_DAC/, this is just not true. I do not understand how to correct these errors.

What is the correct way to import a project from ST into this compiler?

Here are the errors as you can see. /media/uploads/richardv/mbed_undefined_errors.png

Thank you, Richard V

Hello, it seems you are missing the include to the CMSIS Device Header File.

In your case stm32f30x.h and probably the define for the CMSIS Device.

I can't seem to open the stm32f30x.h in your project though. Kind Regards
