TIME$ on raspberry pico

[nbrok]

If i try to set the time with TIME$="FR.10 Mar 2023,17:00:00" I get the message mistake. If it needs a RTC on which GPIO pins does it expect the I2C RTC?

PicoBB is derived from BBCSDL. BBCSDL does not support setting the system clock (see here, therefore PicoBB does not have that capability either.

Since the Pico does have inbuild support for a RTC I will consider adding support for that, but there is always a trade-off between added features and memory available for user programs.

Since most of the C SDK functions are available through the BASIC SYS statement you can always provide your own implementation of the internal or an external RTC.

The link you gave tells something else, Perhaps copied from the original BBC basic manual. So a comment in that manual that BBCSDL doesn't support setting the time$ would be helpful. But I appreciate that you are considering to add rtc functionality.

From the BBC BASIC Manual:

"Because the system clock is a shared resource, and changing it could adversely affect other programs, you can only assign a new value to TIME$ in BBC BASIC for Windows, and only if you have the appropriate administrative privileges."

So you cannot assign a new value to TIME$ in BBCSDL.

Thanks for adding RTC in the newest version, now I can set the internal clock.
