Arduino ide8.16 compilation error on Mac about hulp HOT 6 CLOSED

Hi @ChassaB
What version of esp32-arduino are you using? It must be >=2.0.0 (IDF version 4.x)

from hulp.

Right,
in the Arduino IDE Boards Manager it is 1.0.6 for the ESP32 install, which is the current latest release under the board manager. My version of the IDE is 1.8.16.

Do I need to go to the ESP GIT and find ESP32 core version 2 or do I need to install Arduino IDE V2?

Can you clarify. I'll go looking

from hulp.

Try following the instructions for 2.0.x here: https://github.com/espressif/arduino-esp32#esp32-s2-and-esp32-c3-support
I was under the impression 2.0.0 was released but maybe it's not available in the boards manager yet for some reason.
Updating the IDE sounds like a good idea if you're still having issues.

Yes, the espressif GitHub says it is but not so. I updated to the latest Arduino IDE a couple of days back so it should be up to date but I'll check again tomorrow as I'm now getting the following errors with your example ADC sketch using the ESP32 Dev Module as the selected board.

Sorry, that's because I haven't updated the Arduino example.

If you look at the corresponding IDF example (main/main.cpp) you should see what needs to be changed. I'll fix it soon.

from hulp.

Thanks. Yes I see what needs to be changed;
Replaced
/*ESP_ERROR_CHECK(hulp_configure_analog_pin(PIN_ADC_PIN1));
ESP_ERROR_CHECK(hulp_configure_analog_pin(PIN_ADC_PIN2));
ESP_ERROR_CHECK(hulp_configure_analog_pin(PIN_ADC_PIN3));
ESP_ERROR_CHECK(rtc_gpio_pullup_en(PIN_ADC_PIN3));
*/
with
ESP_ERROR_CHECK(hulp_configure_analog_pin(PIN_ADC_PIN1, ADC_ATTEN_DB_11, ADC_WIDTH_BIT_12));
ESP_ERROR_CHECK(hulp_configure_analog_pin(PIN_ADC_PIN2, ADC_ATTEN_DB_11, ADC_WIDTH_BIT_12));
ESP_ERROR_CHECK(hulp_configure_analog_pin(PIN_ADC_PIN3, ADC_ATTEN_DB_11, ADC_WIDTH_BIT_12));
ESP_ERROR_CHECK(rtc_gpio_pullup_en(PIN_ADC_PIN3));

I assume the additional 2 lines from the IDF example are needed as well?
ESP_ERROR_CHECK(hulp_ulp_load(program, sizeof(program), 1000UL * ULP_WAKEUP_INTERVAL_MS, 0));
ESP_ERROR_CHECK(hulp_ulp_run(0));

Now that it is working I'll have to go through and better understand the code. Haven't done anything with assembler since the 6502 in the early '80s.

Thanks for your help. If I can help with documentation or something I'd be happy to.
