Thank you very much Ttelmah.
I'll try to see if power PWM is good enough.
Do you have any suggestions for a chip with the programmable frequency generator?

Thank you both.
You don't tell us your clock frequency.
I calculated use the code in this post but change to an 8mhz clock and you have better resolution than you need.
I Haven't worked with NCO be ...

I'm trying to write a program to generate frequencies from 20KHz to 50KHz using CCP. The problem is resolution. I need 0.1KHz steps but the best I get with a prescale of 1 and around 50 KHz is 0.7KHz. ...

Thanks for the prompt reply. I see an interrupt in Tick.c but it is the counter 0 interrupt. I think the ENC28J60 causes an external interrupt to the PIC. Every hardware example I see connects INT0 of ...

Does anyone know what file has the interrupt service subroutine that executes for the ENC28J60 in the CCS tcp/ip stack?I have looked for a couple of hours and I can�t seem to find anything. I have a P ...

Thanks for the reply Ttelmah. I did what you said and it works! The RDPU bit still always reads 0 but I have tested my board with a volt meter and when I set RDPU all pins on port d get pulled high an ...

In the data sheet for the 18f4550 it states there is a port D weak pull up option enabled with bit 7 of �port E register� 0xF84 (found on p66, p120 and p123 of the data sheet) which contains port E i ...

Hi everybody,

Recently I bought a prototyping board from mouser.com (part number is 626-DLP2232PB-CCS). It includes a board with two chips: PIC877A & USB interface, and CCS compiler. Both HW an ...

Hi, over the past weekend I was playing with a similar project. I used winhex a program referred to on other post on this form(see link), to manipulate a .wav file. Using windows sound recorder i crea ...

Thank you both for the quick response. Sadly it didn�t occur to me to google it. I haven�t had time to do any further research but it looks like it is an option I probably won�t use for the time being ...

Does anyone know what the WOL (pin 5 on a DIP package) signal does on the ENC28J60? I have a olimex NIC based on the ENC28J60 and its documentation mentions a �WOL� signal on pin 5 of the ENC28J60. T ...

Hi Student,
I�m currently working on a similar project myself. For a possible microprocessor solution you can use a PIC with pulse width modulation hardware like an 18F4431. You can then create a sin ...

Hello CCS community:

I am new to programming pic micro-controllers and am having trouble trying to get two pic16F87/88s to communicate with each other. My seriaI communication with the PC is workin ...
