Can timers be written to as a WORD?

[camerart]

Hi,
I'm setting a TMR0 like this:
TMR0H = %11111111
TMR0L = %11111110
Can they be written to like this:

TMR0 = 1000, or in a similar way.

They can in C but I doubt Vlad made it possible.... Why? Is it an issue!!

Hi I,
I should have asked, which is the 'best way' to write to TMR0? I need to set it to a string/variable received with a serial input.. (1000-2500)

Write a function

If you can't write a word then always write low byte last and read it first. The chips with a 16 bit timer0 have a feature to enable safe reading and writing of 16 bits.

Hi,
How do I separate the WORD into two BYTES? (Oshonsoft BASIC)
C.

 

[Pommie]

Try,
word=readADC()
lowByte = word and 255
highByte = word/256

Or, this may also work, (not familiar with what Osh can do)
lowByte = word
highByte=word>>8

If there is any kind of union in Oshonsoft then you may be able to use that.

Hi M,
I've just tried this, and it looks like it's ok:

tim0h is the ON time of a PIN tim0l is OFF.

tim0h = 65535
TMR0H = tim0h.HB
TMR0L = tim0h.LB
What do you think?

Hi P,
I also read that the LB should be written first, but I tried changing the order of the above example, and it worked.
I'll use LB first though.

Assuming you're still using a 18F4331 then section 11.4 describes the reading and writing of timer0. The register TMR0H is not always TMR0H!!!

Hi M,
Yes, I read that it is a buffer, but I think #8 is ok, thanks.
Still using 18LF4431.

X. HB, X. LB
You have used this before

Hi J,
Ok.
This proves one thing: that you have a better memory than I do

Actually, I was trying to separate the BYTES, but I've now found that the solution at #8 works instead.

Thanks,
C.
