C++ (Cpp) pwm_cleanup Examples

Example #1

File: chip_io_c_pwm.c Project: Groguard/CHIP_IO_C

int cleanupPwm(char *channel)
{
    char key[8];

    clear_error_msg();

    // The !channel fixes issues #50
    if (channel == NULL || strcmp(channel, "\0") == 0) {
        pwm_cleanup();
    } else {
        if (!get_pwm_key(channel, key)) {
            pwm_cleanup();
        }
        pwm_disable(key);
    }
}

Example #2

File: py_pwm.c Project: blsmit5728/adafruit-beaglebone-io-python

// python function cleanup()
static PyObject *py_cleanup(PyObject *self, PyObject *args)
{
    // unexport the PWM
    pwm_cleanup();

    Py_RETURN_NONE;
}

Example #3
