Hi
I am trying to do simple float arithmetic on PIC24 parts.
Nothing seems to work right.
I am using PCD V4.140 (tried also V4.137).
MCU is PIC24FJ128GA106 (I also tried other parts).
MPLAB V8 ... |

Hi Ttelmah
Windows did not ask me for a driver.
How do I go about forcing the driver down its throat?
Best regards

Hi
I just posted a question which may also pertain to your problem.
I too noticed that the processor resets itself.
I entered View->Disassembly and single-stepped until I hit a POP instruction.

Hi
Did anyone succeed in using this part with CCS?
I hesitate to say it but I think I found a silicon bug in the POP instruction.
I single stepped the code in assembly and it looks like the POP ins ... |

Hi
I have a PCB with a PIC18F4550 that works fine with the CCS HID demo.
When I try to use the CDC demo file (ex_usb_serial.c), I get an unknown device in Device Manager, under Other Devices called ... |

Hi
Why don't you use #USE SPI with spi_xfer()?
This alleviates the need to deal with the registers.

Hi
Which pins of the MCU are connected to the EEPROM's SS,SCK,DO and DI?
Are they the SPI hardware pins (except the SS which is a regular I/O pin)?
Do you actually "see" the data coming b ... |

I wrote this code for PIC18F87J11 running at 32MHz, but it can be easily modified to run on almost any other device.
This code runs perfectly in a real product.

You did not explain exactly the nature of the problem in output.
Try adding the following line after #device adc=8:

Mikey,
you are right about the xx not applying to 14.
the 67 and 46 series, on the other hand, is not supported by PICkit2.
Personally, I prefer the the PICkit2 as it is much faster that the 3.
