Toggle LED on TEA128 using P&E generated code.

[saya]

Hi, all,

I was following the P&E example for GPIO LED. I am still a bit uncertain and need a bit more view/explanation about the library generated by P&E for GPIO_LLD.

once you generated the code for GPIO_LLD, I have those functions:

#define GPIO_LED_Init_METHOD_ENABLED   /*!< Init method of the component GPIO_LED is enabled (generated) */

#define GPIO_LED_SetFieldValue_METHOD_ENABLED /*!< SetFieldValue method of the component GPIO_LED is enabled (generated) */

#define GPIO_LED_GetFieldValue_METHOD_ENABLED /*!< GetFieldValue method of the component GPIO_LED is enabled (generated) */

#define GPIO_LED_ClearFieldBits_METHOD_ENABLED /*!< ClearFieldBits method of the component GPIO_LED is enabled (generated) */

#define GPIO_LED_SetFieldBits_METHOD_ENABLED /*!< SetFieldBits method of the component GPIO_LED is enabled (generated) */

#define GPIO_LED_ToggleFieldBits_METHOD_ENABLED /*!< ToggleFieldBits method of the component GPIO_LED is enabled (generated) */

GPIO_LED is the name for my GPIO component.

after GPIO_Init, I am not sure how to turn on the LED and off it because I am not sure what is the field parameter and so is mask.

Could someone give me a simple hint/example of how to use these function? Such as, turn on LEDs.

I attached the generated code from P&E for GPIO.

Any help is appreciated.

Alan

I followed this tutorial and get my working!

Hello Alan Tian:

I am glad you found Erich Styger's tutorial. That tutorial is for using BitIO_LDD component.

In case you are still interested in the GPIO_LDD component I attached an example with this one for TRK-KEA128, which simply turns on the 4 blue leds sequencially.

Also, when in doubt how to use the generated APIs, you can refer to the "Typical Usage". For this right click on the component -> Help on Component, then select "Component xxx Typical Usage"
