@LMESTM I'm not sure that I know what "c pcf f1 f2 f4 l1" is supposed to mean. Could you update the title? |
LMESTM
changed the title

@theotherjimmy - sure, hope it's better now |
|
@LMESTM Much better! I now understand what this PR does! |

Sorry for the ABORT everyone, need to prioritize a few PR CI jobs for the upcoming release. |

@LMESTM Looks like this needs a rebase please. |

@LMESTM can you resolve the conflict? |

There were still side effects, in particular on I2C master slave test, when setting by default the Pin Speed for F1 family. So for F1 family, let's do it only in case of Output which is the only case where this actually applies on this family.
As reported in issue ARMmbed#4214, there are seen issues seen first on NUCLEO_F103RB in case of successive Reads of 1 byte at a time. This issue is due to a wrong state management in the end of read sequence. Also F1 i2c driver was not fully aligned to others, which is updated here.
