PIC32MX in DIP forms

[Brian Griffin]

Please note that the "TimeDelay.h" inside the Microchip Application library has a bit of a problem. The delays are a bit off in a few more miliseconds which could affect the program flow if timing is used. It could be my breadboarded setup, or my crystal (it's in 10MHz instead of 8) or both. I will contact Microchip for further information.

Here's a temporary workaround for it, using a Timer. Add this function inside your code.

CODE: SELECT_ALL_CODE

void delay_ms(unsigned int count)
{
   T1CON = 0x8030;      // turn on timer, prescaler to 256
   while(count--)
   {
      TMR1 = 0;
      while(TMR1 < 0x4e);
   }
   T1CONbits.ON = 0;
}

(Setup information: 10MHz crystal PLL to 40MHz, Peripheral bus = 20MHz, prescaler 256)

Just put the desired no. of miliseconds inside the function.

Woh...... this is super fast you guys, I am behind still in 8-bit microcontroller only

Good to see Malaysia is getting into this, keep it up man!

You don't have to get stuck at 8-bit platforms. One has to scale the applications according to the needs.

I have the dsPIC solely for sound and signal generation. The PIC16/18F is not tuned to that kind of thing. I had been planning to do wavelet/FFT on ASM but didn't do it due to time constraints.

Right here, I have a wave player on the PIC32MX with Microchip MDDFS library. It's playing some sound files. Will fine tune that when I come back from work.

Yes, I got mine too. It's the 28-SPDIP PIC32MX220F032B. I've started to play with this new PIC32 running with 8MHz crystal.

Oh... I hope I can try this, but being tied work

Thanks everyone for sharing here.

No problem man. This stuff is really good.

Right now the next batch of these chips are only available early next year (January 2012). They might be coming up with higher end versions with more prog. memory and RAM.

OK, you are not alone, I am out of date too Never touches this monster, but I really like to try it out. Maybe Cytron should come out with the starter kit for this monster?

But do we need to upgrade the UIC00B to PICkit3? I really like UIC00B, been serving me for some time and I am satisfy with it.
