Tutorial/Docu to event Handlers of nrf_esb example code

[florian2840]

Hello all,

i am struggling with the example code of the Enhanced ShockBurst Protocoll in SDK 11. I cannot really see the structure of the code, to which time which event occurs. Is there a tutorial or a documentation out there which explains the general idea of the event handling to get the concept/idea behind it.

For example I cant find the interrupt handler for the button press. The example code provides the functionality if I press one button the development board send a message to another nRF52 chip. Where I find the Handler which handles this button interrupt?

Thanks in advance,

Florian

Exactly which example are you looking at? Is it "esb_ptx" or "esb_low_power_prx"? Or a different one?

i am looking at the esb_ptx. There is one function called gpio_check_and_esb_tx() which is always called when I press one of the four buttons. But I do not know why. Which Handler calls this function?

Hi.

Our examples are described on their page in the infocenter. You can find the description for the esb_low_power_ptx here.

In the rsb low power example, the chip goes to system off after setting the leds and sending the packet. The button click wakes up the chip, and it restarts from main(). The chip is set to wake on pins in gpio_init()

You can find more info about ESB here, and basic tutorials for the board here.
