Maxim 1-wire libraries I2C breaks on STM32 moving from mbed-os v5.x to v6.x

@mattjarvisast I agree, sorry for hijacking your thread.

I’ve posted a new thread at DS1820 / OneWire library doesn't work on mbedos5, mbedos6 (NUCLEO-F303RE)

Thanks for sharing your working configuration.

edit: Problem ultimately solved by using a 20kOhm pullup instead, or using many (>=5) DS18B20 on the same bus.
