Hello everybody,
I have a counter to count the number of turns. For this I need to memorize the number of turns and exceed the number 255. How can I memorize the number 300 or 1000?
Thank you in advance!

Hi Samtim,
You just need to save a 16 bit number - so first byte as
(or Value >> 8 )and second byte as
(Note for the second byte you can just use
as it will be 'truncated' to 8 bits or
both of which are quicker than the modulus calculation..

Hello everybody,
A flowchart with an example would help me. I tried something, but I don't know if it's okay. Thanks Martin for the answer. Attach a flowchart.

Hi samtin,
Following this
post
Attached is how I would achieve what you are after.
Note:
As EEPROM has 1,000,000 erase/write cycles, it best to write to it as infrequent as possible.

Hi Martin,
I understand better now. Thank you very much Martin. I attach a flowchart, if you want to look a little.

Hi samtin,
Your welcome.
Glad us martin's has helped.
Calculation box can be deleted.
I was going to use it but changed my mind.
Was in a rush for dinner so deleting it slipped my mind.
The Calculation box with
can also be deleted as was for testing only.
Although I would strongly recommend either use the calculation box to assign an initial value.
Alternatively, delete the
as suggested.
Edit
value variable, then assign an initial value:
- Edit_Variable_Name.png (57.72 KiB) Viewed 5253 times
Reason for this is in Flowcode simulator, variables start of with an initial value of 0.
On your hardware, it will be some random value.
General rule of thumb:
If a variable is read first then it must have an initial value assigned.
If a variable is wrote first then an initial value is not required.

Hi Mr. Martin,
Thank you very much, Mr. Martin. Any answer from you on the forum is for me a lesson and a book page for what Flowcode means.
All the best!
