Dear Sir/Madam,

I have run f2838x_cpu1_echoback succesfully. Now, I want to apply a simple project into echoback. I want to replace 'Switch1' -> 'Switch8' with 'GPIO0' -> 'GPIO7' to trigger the external leds.

Do you have any example like that? If you do, please share it with me.

Best regards,

Tri.

Dear Sir,

I finally can run external leds by adding 'GPIO_writePin(1, Switches0x6000.Switch1)' into do while. Now, I want to send decimal number from 'LEDx' to 'Switchx'.

For example, I write 5 in 'LED1' and then 'Switch1' receive value 5.

Could you please help me?

Best regards,

Tri.

Those LED/Switch are only bit values. If you can make the data, mode, and speed parameters work for your application, that will be the fastest method.

Otherwise, you need to edit the object dictionary and the ESI file to match the type changes you want. I don't have any specific documentation on this.

You may find useful documentation on learning more about the ESI files and other EtherCAT items on http://www.ethercat.org/

Best regards

Chris
