External Int Input 12F615

[Benj]

Hello.

You may be able to use the key mappings to assign a keyboard key press to simulate the switch being clicked.

Or visa versa you can try holding down the mouse on the switch and using the function keys to step through the program.

Hi Steff,
I have posted more about key mapping here.

I Find key mapping a very useful feature indeed.

Thanks for the help.
The simulation now works well.
However, when I burn the small test program on the chip, it does not work. On a 12F615 it runs. On 16F1824 not.
The simulation runs with both chips.
Am I doing something wrong? What I noticed is that at the 16F1824, not all oscilator options are available. Is that a reason?

I want to use the 16F1824 with the internal oscilator without clk out, if is possible with a 19660800hz clk. I do not find this option.

Hello,

The 16F1824's internal oscillator probably cannot handle 19.6608MHz or if it can it will have to be done by enabling and configuring the PLL using a C icon at the start of your program.

I would suggest doing a 1 second LED flasher test with the internal oscillator enabled and try to see what frequency your getting. On the 16F1824 the internal oscillator defaults 500khz but can be switched to 16MHz using the following C code.

Code: Select all

osccon = 0x78;

This code should give you 32MHz but not 100% sure it will work.

Code: Select all

osccon = 0xF0;

The same problem again and again ?
At least a similar, only the Pic is different .
I need the Ext Int input(RA2, Pin 17), the simulation does not work or I do something wrong. Can someone help me ?
I would like use the 16F1507, in the appendix a small test program. I work with Flowcode 6.

Hello,

Thanks for letting us know. The Interrupt pin was set to be PortB bit 0 in the definition file which wasn't correct.

I have now moved the pin to PortA bit 2 which should be correct.

Simply copy the attached file into your "Flowcode 6/FCD/PIC" folder and restart Flowcode for the changes to be loaded.

Thanks a Lot ...now it works
