[help] setup pwm frequency for Tiva C in Energia

[hvbon2010 0]

Hello everyone,

I'm trying setup pwm frequency for tiva C in Energia but failed at this line: analogFrequency(PWM_FREQ)

// define PWM pins
#define PWM_1 PD_6

// define PWM frequency
#define PWM_FREQ 20000

void setup()
{
  pinMode(PWM_1, OUTPUT);
  analogFrequency(PWM_FREQ);
}

void loop()
{
   analogWrite(PWM_1, 50);
}

 

Can help me with the problem, thank!

I recognized some problems:

1. How to use Tivaware for Energia to configure frequency PWM

2. How to fix pin_map.h problem

Resolve:

Problem 1: After install Energia  1.6.10E18 version, run Energia and select: board --> boards manager --> install Energia Tivac board

                  After installed Energia Tivac, Tivaware library is taken your system following link:

                  /home/bonho/.energia15/packages/energia/hardware/tivac/1.0.2/system/driverlib

Where bonho is my PC name, this link is hidden, to see this link in your PC, select view ---> show hidden file on the taskbar

                  Create new file in Enrgia, include Energia file as file is included below

                  I has one example to you compare between CCS programing and Energia programing included below 

Problem 2: preference this topic: I fixed the problem success

 

GPIO.h

include.h

pin_map_tm4c123gh6pm.h
