The RTC driver topic

[Giovanni]

Probably the check on RTC_CLK should go in rtc_lld.h instead of hal_lld.h because if the RTC is not enabled there is not such constraint.

I don't like to depend from time.h because it is possible other compilers don't have it

Using headers from standard lib may be not ideal decision, but bad standard is better than nothing.

Agree, done.

Thank you, I will verify if that header is present in all compilers else we will do something else.

Are there any technical reasons behind change of SERIAL_DEFAULT_BITRATE
value from overall default 38400 Bd to 9600 Bd in testhal\STM32F4xx\RTC\halconf.h

[barthess]

Jacon,
No. I played with it during debug and forget to change to default value.

Giovanni,
I retested code after merging. Works as expected.

[Giovanni]

Excellent, thank you

Giovanni,
What the next steps related to RTC driver? If nothing than I will continue SDC driver.

[Giovanni]

I just will do some minor reformatting using Eclipse rules, you may proceed with SDC, I think that one will be more complex. I saw some interesting threads regarding SD+DMA in the ST forum, probably you should read those too.
