internal clock

[wardnica]

I need to count how many pulses there are on my C0 input in 1 minute .. but the timer is totally not right.. i think its the clock speed settings, what value do i need to set (using a PIC16f690) in flowcode?

Hello,

If you are posting about a Flowcode program please post your question in the relevant section, I will move this question into the relevant section, if it is Flowcode V4 you will need to get your forum account upgraded to be part of the V4 forum group.

Instructions on doing this are available here: http://www.matrixmultimedia.com/support ... f=29&t=602

Hello,

The internal clock speed will not be 100% accurate but you should be able to get fairly close.

For a 16F690 device the internal clock speed is defaulted to 4MHz so you would put 4000000 in the Flowcode project options for the clock speed.

If you want to you can change the oscillator speed to 8MHz by using this line of C code at the start of your program.

osccon = 0x71;
