Convert existing 'c' file to a sketch and add code

[brcisna]

Hello All,

Very new to trying coding in the Arduino IDE.
-rtlduino-

Have an existing .c file - example_wlan_repeater , from the amebad_sdk that 'almost' does what I would like it to do albiet i would like to add a function of,when the repeater makes a connection to the AP ( drone AP), the led would blink slowly,dimmly, to verify the repeater actually has a connection to the drone. This .c file does not have the 'LED lights on connection' function.

'example_wlan_repeater .c '

#include "FreeRTOS.h"
#include "task.h"
#include <platform/platform_stdlib.h>

#include "lwip_netconf.h"
#include "wifi_conf.h"

extern init_done_ptr p_wlan_init_done_callback;

Can anyone help on this , in regards to adding the needed code and if it is possible to have a 'converter from the C file to sketch?

Thank You

Not without code I can read. Please read the forum instructions.

10-4 figured out formatting ,,sorry bout that

I think the first thing you will need is an Ameba core:

Hi John,

I have been messing with the ambd_sdk for about three weeks now so am somewhat familiar with that part. I can compile what i want in the example_wlan_repeater c file and works fine other than it does not have the possibilty of getting the LED to blink, once the repeater --rtlduino /BW16- is actually connected to the target AP. AKA: drone AP. This is the part I am missing and am not smart enough to know how to add the code to that 'c' file,,I'll be the first to admit.
Also have the amebad board, libraries added to the Arduino IDE as this can be used to flash natively the binaries generated via commandline ,from the ambd_sdk, to Rrtlduino modules, boards.

Thanks
