Hello,

I am using light sleep on an ESP32. I have a button with a pullup attached to pin 34, which pulls pin 34 to ground when pressed.I use gpio_wakeup_enable(34, GPIO_INTR_LOW_LEVEL) to enable waking from light sleep on this pin. I have an edge interrupt on this pin too for use when the program ...

Hi guys,

I've searched and examined headers for quite some time but am yet to come up with an answer. Is there a function or macro that will map a gpio_num_t to adc1_channel_t? There is an adc1_pad_get_io_num function which converts adc1_channel_t to gpio_num_t (i.e. ADC channel to GPIO pin), but ...

I've managed to fix the example code so that it'll compile with C++!

The erroring lines (81-85 and 376-381) are actually structs of type sockaddr_in and mwifi_config_t. C supports designated initializers whereas C++ does not, and apparently even when compiled with 'extern "C"' around them, they're ...

I've posted a comment on the Github issue relating to this, as I still feel the examples should compile as C++ without having to include the functions through a class.

Do you have app_main1() defined in get_started.h and in get_started.c? You should then have app_main() defined in lee.cpp only


Yup.


A couple of other thoughts....
1. you did put the lee files and the get_started.h in the main directory with the get_started.c file?
2. you could try a "make ...

Thanks again Lee for your help, I've renamed get_started.cpp back to get_started.c, and - this is getting ridiculous now - it compiles, but the linker can't find app_main... I guess the linker is ignoring the lee.o file.

Thanks again Lee for your reply.

I completely reset my esp-mdf directory so it's identical to the Espressif repo. I've tried your files in the main directory but unfortunately I still get the same errors as before... arrgh!

Thanks again for your quick reply Lee.

I'm simply using make, with no options.

Unfortunately it still doesn't compile after casting the malloc. I now get a vast number of errors and warnings. A lot of them seem to be related to designated initializers, which don't exist in C++, and the compiler still isn't happy when the struct with designated initializers is wrapped in extern ...

Hi Lee,
Many thanks for your reply.

I am compiling it in VScode on macOS, but through its built-in terminal; I'm just using VScode as a text editor.

Sorry I should have noted previously that it compiles and runs fine when it's just the original unmodified .c file without the extern C - including ...
