Hi there,

I'm using flowcode and a 8-pin PIC12F629 where I want to use all 6 I/O pins. Simulation runs OK in flowcode but when inserted in the chip with multiprogrammer, it doesn't work.
3 I/O lines are connected to other devices like MCLR and OSC.
Does anyone have suggestions on this?

Hello

Do you have the latest version of Flowcode?

The latest version comes with an updated definition file for the PICmicro.

Also the MCLR pin can only be used as an input.

Hope this helps.

You can program the device in the multiprogrammer, but it the connections to the OSC pins are not useable as i/o lines within the multiprogrammer itself. Because the MCLR pin is an input only, it can be used within the multiprogrammer (it is connected to the RESET button).

You would need to transfer the PICmicro to your own hardware to gain access to the 2 OSC pins as i/o lines.
