Flowcode Support Board

I cannot compile to a pic 16F690.
the error message is:
Compilation successful!
Using «PICkit3 PK3CMD Extemal Power> inbuilt settings for linker

i have tried changing the parameter -L to -V5 or -V3.3v to no avail.
Can anybody help?

The command line option if you want the PICKit to power the board is -W5.0 or try /W which sets the voltage.

Hello,

The -L parameter is for 16-bit PICs only, try removing the -L and hopefully it should work.

Hi Ben, i have found changing the parameters does not work, it failed to initialize.
I tried compiling to HEX, using the MPLABX IPE v5.50. it programmed the pic as far as correctly assigning ports but didn't program the delay function.
osc, timer ? Any advice?
would changing the Pickit 3 to pickit 4 help with the compile to target?
thanks again.

Further to the above, the clk out on the pic measured at 1mhz, i thought it should be 1/4 of the osc?
my project options were: 16F690, internal RC clock out, 20mhz clock speed, no watch dog, programmer port n/a.
any help is appreciated.

I have changed the clock speed to 4mhz, the delay now works!!

Hello
These posts relate to you as the default internal osc speed is 4MHz.

On the above link there should be enough information to change the internal osc speed from 4 MHz to the maximum internal osc speed 8 MHz

thank you for your help!
