Problem with timer-based PWM on a 16-bit CCP.

Other Parts Discussed in Thread: TM4C123GH6PM

Hi,

    I want to genarate PWM using timer0, so I had added the API for timer based PWM from tivaware ver 1.1. But I had got the error during compiling, need solution.

Build target 'Target 1'
compiling pwm.c...
C:\ti\TivaWare_C_Series-1.1\examples\peripherals\timer\pwm.c(42): error:  #5: cannot open source input file "inc/hw_gpio.h": No such file or directory
  #include "inc/hw_gpio.h"
C:\ti\TivaWare_C_Series-1.1\examples\peripherals\timer\pwm.c: 0 warnings, 1 error
".\pwmtimer0.axf" - 1 Error(s), 0 Warning(s).
Target not created

    Might your solution lie in "telling" your IDE your MCU's part number and Rev identification?  Many, many posts here detail, "how/where/why..."

    Should such info exist - and be proper in location & format - some way/how your "link" to the containing driver library is unclear to your compiler...  (again - solved via same resource as above)

    I am using TM4C123GH6PM ,Keil IDE and the tivaware revision 2.1. I had done API project from tivaware ie from the examples->project folder in tivaware and worked successfully. But in the same way I had done the settings in my current project(timer0 based pwm) but failed.Also I want to know how to set the linker options ie scatter file and Misc controls.Below attaching the screen shots

    Hi,

        I want to know the options for target settings for tiva c series (TM4C123GH6PM). I am using Keil IDE and tivaware revision 2.1. I had already done the example project from tivaware and worked successfully. In the same way I had done my current project(timer0 based pwm) but compiled with errors. I had added the driver library and done the proper settings in the target options need solution

    Hi,

    To get rid of these errors, you need to add the Tiva installation folder path to Search include options - don' t know where it is in Keil; for CCS is simpler. You can find out by opening an already good working project and watching/learning all compiler/linker options - you need to do that, it will be useful for next projects. Take into account that each project may need its special "tweking/tunning" so you need to know where all this can be done.
