Re: HID Profile

I would like my ESP32 to act as a bluetooth keyboard. As I understand, this is not currently possible. Will support for the HID profile allow this? Is there any progress on this matter?

Forum search broken?

Does anybody have suggestions how to use the search on this forum? For example, I tried to find information on the ADC, and I got the error message: "The following words in your search query were ignored because they are too common words: adc." I really don't want to post a question that has been an...

Re: Atomic operations with <stdatomic.h> in IDF?

I was able to fix the errors by including esp_types.h first:

Code: Select all

#include <esp_types.h>
#include <stdatomic.h>

Atomic operations with <stdatomic.h> in IDF?

Hi! I'm trying to write an ISR for a quadrature encoder. My function needs to xor a global variable and increments a global counter. I figured the correct way to do that would be by using atomic operations defined in <stdatomic.h>. However, when I include this header file, I get a lot of error messa...

Re: LED-PWM example for a beginner?

Thanks a lot, Angus! That example helped a lot, I was able to get it working. It turned out to be really simple: - first call ledc_channel_config() to set up a PWM channel - then call ledc_timer_config() to set up a timer There's one caveat: don't switch the order of the calls. I tried to set up the...

Re: LED-PWM example for a beginner?

I've already seen that example. But as far as I understand, this just works if I use the Arduino IDE, right? Those ledc-funtions are not available in IDF, are they? I don't want to use the Arduino IDE since it is still missing a few important bits (as far as I understand UDP and analog read are stil...

LED-PWM example for a beginner?

Hi! I've just started programming the ESP32 with IDF, and I am a complete beginner. I've managed to set up the tool chain and flash some examples. The next step I want to take is to control a motor with a PWM signal. It looks like the LED-PWM function of ESP32 is very versatile, but I am a bit overw...
