Hi,

I have 2 problems i'm facing using the dspic33EP64MC502.
Firstly, I'm using the ccs compiler version 4.130

My first problem is that I'm unsure how to set the clock. According to the datas ...

Thanks Ttelmah. I was on a long break. Anway this helps my understanding better.

So if I use a 20MHz crystal, I must set PLL5. Then at the #USE DELAY, do I write it as #USE DELAY(clock=48MHz) even ...

Hmm. In that case do I use a 4MHz crystal? And if I do, should my clock statement be 16MHz since Im running PLL? Actually I dont know much about PLL, just that i think it multiplies the crystal freque ...

These 2 fuses you mentioned, aren't among the list of fuses for the 18f25j50. How do I go about to turning it on in that case?

Thats strange...I just realised a simple program to send a byte over rs232 also doesn't work with this chip. And I've used rs232 many times with other chips. It just hangs when it reaches the putc or ...

Also, should the 'usb_task()' function automatically get the usb connection enumerated? Or is there something else I need to add after that?

And, does the D+ and D- lines have to be pulled up or do ...

I've tried using just usb_init(). And also the cdcntxpvista.inf driver. It still doesnt work. Windows says it 'found driver software for your software but encountered an error while attempting to inst ...

Normally when I try installing the cdc9Xpt1.inf file as its driver, it does show 'usb to rs232'. But when i click next to install, it says 'windows encountered a problem installing the driver for your ...

Hi,

I've been trying for days now trying to get windows to recognize my usb connection but all i keep getting is a 'usb device not recognized message'.
I just need to be able to transfer data thro ...

When I try updating the driver with the 'CDC_NTXPVista.inf' once windows states ' usb device not recognized', it does show 'USB to rs232' in the update driver screen. However when i click next to inst ...

I've been trying to get the PC to recognize the USB connection with my pic, but all the examples I try doesn't work.

I'm using a pic18f25j50 with a 20Mhz crystal, trying to connect to windows 7. M ...

Thanks for all the feedback

I managed to find the link to the datasheet of a very similar model M0006890K. The one I'm gonna use is the M0006890C.

Look ...

asmboy, I'm not sure what do you mean by opaque and non iluminating. The device is an absolute encoder.

So Ttelmah and FVM, the suggested way to do this is by using a FPGA? Looks like I have some ...

I need to communicated with a device at 4Mbps and each of its frames are 18 bits long including the start and stop bits.

Can this be done?
