Ds18b20 and OneWire protocol error

Hello I’ve using temperature sensor several times in the recent past with other boards with no problems but now I can not make it work on xiao esp32c6.

On compilation i get this:

c:\Users\david.atauri\Documents\Arduino\libraries\OneWire\util/OneWire_direct_gpio.h:174:25: error: no match for ‘operator>>’ (operand types are ‘volatile gpio_in_reg_t’ and ‘uint32_t’ {aka ‘long unsigned int’})
174 | return (GPIO.in >> pin) & 0x1;
| ~~~~~~~ ^~ ~~~
| | |
| | uint32_t {aka long unsigned int}
| volatile gpio_in_reg_t

I have tried diferent versions and I can avoid the error but no readings (device is not found)

Any clue??
Thanks

Tested with old esp32 wroom and it works

Hi there,
Well without seeing the code in question, I would try using the GPIO pin numbers instead of the logical numbers. I would try that.
If not then perhaps post the code using the code tags above “</>” and paste it in there.

I am finally using the library OnewireNG instead of OneWire. That one works with no problems
