Compiler 4.135 porting code from a PIC18F87K22 to a PIC18F66K22.

Everything went well and the code worked.
Code ROM used shown as 34% and RAM 12%-14%

But adding just a few lines of simple code ...

The default RTC code assumes you want to use the T1 external oscillator...
The behaviour varies with compiler version. On older compilers you had to explicitly enable/start the secondary oscillator, ...

Here is some code I have got working on a PICDEM PIC18 board with a PIC 18F87K22.

I recommend always start prototyping code with WORKING hardware that use the same device as you intend to use in ...

Hi

I am using a PIC18F87K22 and CCS 4.135

My timer1 interrupt routine works unless the RTCC is setup. However I wish to use both.

In my initalize routine I have

// Tick Timer

The erase_program_memory() section in loader_pcd.c is required. Memory will be erased prior to loading the bootloader code using an ICD3, but then the boot loader writes to the flash. Then the next a ...

#PIN_SELECT _is only used on peripherals that are re-mappable_. Your chip does not offer this on the SPI, so what on earth are you doing trying to use it?. Of course it won't work, the hardware is not ...

Seriously, just use the CCS functions.....

However comments:

1) Use the CCS automatic register locating. Much less likely to go wrong.
So:

#word SPI1BUF = getenv("SSPBUF") // SP ...

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 ...

It'd really help us help you if you said which PIC you're using as well as compiler version, might as well say which eeprom too.....
The more information you supply the faster someone here can reply ...

I have been trying to port some code from a C18 compiler to read and write to an eeprom via SPI.

I can write data out and see the data and the clock on an oscilloscope. However I do not get data be ...

I've seen in your code that you are mapping 2 UARTs:
#define IRDA_RCV PIN_D14
#define IRDA_XMIT PIN_D15
#define TEST_RCV PIN_D12
#define TEST_XMIT PIN_D8
// Maps UART1 ...

Thanks for posting the driver.
Could you also post it in the Code Library forum? There it will be easier for people to find.

BTW: do you know why there are functions i_write and initWrite ? Apart ...

I'm not sure if this has been answered before but I couldn't find a topic about this question. I'm working with a PIC24FJ128GB106 and I need to program a USB bootloader for it.
Does anyone have a va ...
