A cut-down version of https://os.mbed.com/users/Sissors/code/DS1820/ tweaked for use with the STM32F103. It is all generic Mbed operations though, so should be usable anywhere. Non-essential functions have been removed, as this is intended for use within a tutorial.
Dependents: STM32F103C8T6_DS18B20 stm32f103c8t6-ds18b20

Removed specialized STM code (still uses OpenDrain mode), should work now still.

;
; Added NRF51822 support by adding a software delay function.
Switched for STM devices to OpenDrain mode. Since also OpenDrain mode is bugged for STM devices it has a workaround to properly enable it. Should be removed once STM fixes it in the mbed lib.

Fixed issue with multplie probes
;
; The command byte got garbled after first sent, resulting in other runs no probes responding.
Renamed all CRC to _CRC to remove conflict with STM devices.

Renamed all CRC to _CRC to remove conflict with STM devices.
;
; Also changed some constants from double to float to stop compiler warnings.
