Does flow code support the use of standard C programming like the following in the decision?

great than or less than <>
Not equal to !=

I have to read a 4 bit binary value from ra0,ra1,ra2, ra4. If I read on only those bits, can I shift bit 4 over to bit 3 without effecting bits 0 to 2? The only other way I could think of is to read bits into a variable and bit 4 into another variable, then shifting one var and then using OR to comb...

perfect! thanks!

I need the internal pullup resistors enabled on some pins. How do I enable them from flowcode?

..or do I need to do that in C? If so what is the C code that enables them (16f616 chip)

Im trying to use flowcode 4 and the simulation does not seem to output anything to the pins.. Its a simple interrupt that outputs seconds to port a.
Are variables available inside interrupts to read and write and do you have to return values?

I knew I was missing something! Thank you I "got" it now.

I was looking at the sample code for a 1 second timer. In the example the clock is 19660800 Hz , the scaler is 256 and in the interrupt counts to 75 then adds to the second counter. 19660800 / 4 / 256 = 19200 hz that the interrupt is called. It runs 75 times before the second is advanced. How exactl...

Ok, thanks.

So now for the prescaler question. At 4 Mhz, the counters run at 1 Mhz correct?

I am using a 16hv616 chip and I want to have a counter that increments every second. I plan to use the internal oscillator, but flow code 4 does not have internal as an option in chip configure options... Is this a problem?

Thank you.

I am programming a pic 16HV616 device to sample analog voltage and then adjust output signal timing(in seconds). I need to read the timers 0, 1, and 2. I am using flowcode 4 and don't know how to set an manually read(get the timer value into a variable) the timers. I do not plan on using interrupts....
