The converted program compiles fine, and most (not all) project settings like clock modes etc. show up correctly when I choose "Edit Project".
However, when I burn the resulting HEX file into the chip the program does not work - nothing is blinking (while it is blinking fine, at a frequency of 2 Hz, when the old, unconverted program is compiled with the old compiler).
I am using an external crystal (16 MHz, I know, slightly above spec but it works perfectly fine) with x8 PLL enabled, so the actual clock speed is 128 MHz.
Closer inspection shows that while dsPIC Pro reports correct settings, the dsPICflash (V4.02) program has almost everything messed up, including the oscillator and PLL setup. No wonder it does not work!
So I manually corrected all the settings in dsPICflash and downloaded again. Result: the LEDs are now blinking, but only half as fast as they are supposed to. I checked and both MikroC and MikroC Pro claim the clock speed is defined as (correct) 128 MHz, but I suspect the Pro compiler is using a factor that is off by 2?
I will zip up the two projects and send them to customer support as well so you can have a look yourself.

Here is the C code:
Code: Select all
void main ()
{
TRISB = 0x00;
TRISE = 0x00;
while (1)
{
LATB = 0xff;
LATE = 0xff;
Delay_ms (250);
LATB = 0x00;
LATE = 0x00;
Delay_ms (250);
}
}
