Q:
How do you use the ZIP LED expansion connections? Do they need to be enabled? how do you refer to them when programming? Examples please?

Asked by: Alex Clewett
A:
Hi Alex,
Thank you for your question, you do not need to enable the LEDs. You would control them from Pin 0 in the same manner as the blog below.

Q:
How is the RTC addressed? Could I use the Makecode Blocks with https://www.kitronik.co.uk/4616-real-time-clock-module.html connected to a BBC Microbit instead?
Asked by: Keith Harding
A:
Hi Keith,

We address the RTC board through an I2C chip I believe. You could in theory use the 4616 clock board with make code but you would need to code your own blocks, address your pins and so on which would be quite involved. It's cheaper and easier to use our clock board that we have set up to work with make code.

Best Regards

Cullen

Q:
Do you have any examples of using the makecode blocks for the RTC? It seems as soon as I include a block from the RTC extension it stops everything else in my program from working....
Asked by: Alex Clewett
A:
Hi Alex, I'm sorry to hear you are having problems with the RTC board. We are working on some examples for this board but currently all we have is the example code shown in the datasheet on page 2. If you are still having problems with that code let us know.

Q:
How clever is the RTC? By which I mean does it cope with leap years, summer time and so on. Thanks
Asked by: Dr Marty Jopson
A:
Hi Marty, We got most the way to make it clever. The code will cope with a leap year as it will check for this and default the date to either 28th or 29th were appropriate. However as British summer time changes from year to year it wasn't possible for us to have it detect that, it would just be a case of offsetting the time by either +/- 1 hour depending on what is needed.
