CMSIS Breaks Code

Posted by rog57 on December 19, 2012
Hi,
I've successfully built the "Webserver demo" under IAR EWARM 6.5. As per the README file, I have been able to remove unwanted code (USB, ENET) and rebuilt the code without warning or error.
Now I want to start adding my code in. First, I create a group called "Drivers" and include the appropriate CMSIS driver source files and their include paths. I also add the file "system_LPC17xx.c". I then do a build without warnings or errors.
I then add the include file "debugf_frmwrk.h" into the "main.c" file. I then get multiple repeats of this error:

Error[Pe020]: identifier "LPC_UART_TypeDef" is undefined C:\Users\grr\Documents\IAR Embedded Workbench\arm\examples\NXP\LPC17xx\LPC1700CMSIS\Drivers\include\lpc17xx_uart.h 578

Any suggestions on what is wrong?

thank you for the assistance,
Gary

“I've successfully built the "Webserver demo" under IAR EWARM 6.5.”


Which demo? Where did you get the project from?


“Error[Pe020]: identifier "LPC_UART_TypeDef" is undefined C:\Users\grr\Documents\IAR Embedded Workbench\arm\examples\NXP\LPC17xx\LPC1700CMSIS\Drivers\include\lpc17xx_uart.h 578 ”


Without wanting to state the obvious, it looks like a header file that defines LPC_UART_TypeDef is not included where it should be. Is LPC17xx_uart.h included from a FreeRTOS file? If so then there must be a header file that needs including before it.

Another thought, I'm not familiar with the NXP libraries but some libraries from other manufactures have a config file that you need to set to say which peripherals to include and which to exclude. Maybe UART is excluded from the build?

Hi,

Thanks for the input. I had 2 lpc17xx.h header files; I've fixed that and a few other things. it now compiles and just about runs.
I have posted a new question on this issue.
