Simple ramp generation test using utilities/rampgen library

It demonstrates how to run ramp generator library(rampgen). This test generates ramp signal of frequency 1KHz and passing generated software ramp signal to output DAC port.

Files and directory structure

Folder/Files	Description
rampgen_main.c	Main function for rampgen test
rampgen.h	rampgen library header file
ramplib.syscfg	DAC configuration as per test usage

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
	r5fss0-0 freertos
Toolchain	ti-arm-clang
Boards	am263x-cc
Example folder	examples/utilities/rampgen

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects ).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles ).
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run

Sample Output

Shown below is a sample output when the application is run,

Output will be the ramp signal with 1KHz frequency as shown in figure and can be observed from DAC port for 10sec:
