How can I read register values into flowcode

[Desdewit]

Hi

How can I read the values of RTCVALL & RTCVALH into flowcode to send it via USBSerial?
I,m trying to setup the RTCC to display via USBSerial but don't know how to read the values from within flowcode.

Hi Desdewit,
I have mentioned how do read registers in this post:

Hi Martin

Thanks for the reply.
Not sure what I'm doing wrong but I keep getting errors like below.

Breeze RTCC.c(735:26): error: error in built-in assembly
Breeze RTCC.c(737:2): error: error in built-in assembly

Using a C code within assembly cauld cause that error.
Try attached file.

Hi Martin

Thanks for pointing out my noob mistake, getting the clock to run is even more difficult than I thought it would be.
I tried to do most of the setup in asm but now I’m stuck getting the date and time data into flowcode
Do you know of anyone that managed to get the on chip RTCC running in flowcode.

I have not tried an on chip RTCC before, but I have created a flowchart to read time and date from a dedicated RTCC the is built in to this:

It uses I2C for communications.

Somehow I don't think its suitable for your needs?

If you want me to post it let me know, otherwise I'm sorry can help you with on chip version.
