Hello i have installed eclipse and the espressif sdk and the example blinky 2 worked great as shown in code 1 bellow.
Then i have found a manual which gives the code shown bellow called code 2
When i Complied code 2 instead of the bilinky 2 code 1 it showed no error,but it didnt blink either.
I think its because we used the wrong GPIO.
I cant understand the meaning of the CODE2
there is flash stuff, and ATTR,flash map
PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO2_U, FUNC_GPIO2);
gpio_output_set(0, 0, (1 << LED), 0);
What kind of code it is? it differs alot from EFR32 simplisity studio.
Is there some place i cant learn the meaning of these terms?
