Alastair D'Silva / DS1820

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.

Dependencies:   LinkedList

Dependents:   STM32F103C8T6_DS18B20 stm32f103c8t6-ds18b20

15:236eb8f8e73a 2017-03-11 Removed specialized STM code (still uses OpenDrain mode), should work now still. File  Diff  Annotate
14:c591209285e9 2017-01-08 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. File  Diff  Annotate

8:d87e11e8d012 2014-07-08 Instead of open drain use CMOS output for writing. Not according to standard, but can help for long busses. And helps with parasite powered via data pin (no external mosfet) File  Diff  Annotate
