I compiled "EX_PCD_Bootloader.c" for PIC24FJ256DA206 and programmed it into the chip.
It works normally but when I press the reprogram push button upon reset, I can't reprogram the device. ...

Thanks guys
Ttelmah's first solution is exactly what I was looking for.

Thanks Smile

Thanks for your answer asmboy.
arbitrary offset is what I need.
and what's the problem with the ccs function?
Nothing. I just wanted to be able to assign the return value of a Boolean function to a ...

Is there a function or a macro to write a Boolean variable to a bit in another variable? If not, how can I write one?

like this:
a.7 = f_boolean();
or
func(a , 7 ,f_boolean() ...

Dear "nasr". You are the reason we can't have nice things.

Hi Ttelmah. Thanks.
I tested your code and it works goodly. I disabled GIE after buffer is all out.

Thanks Mike
The Interrupt is simply an INT_TIMER2 and counts a timeout variable and if code is stuck somewhere (in an external eeprom routine) it prints something and halts(while(true);) right there ...

Hi
As you know, there is a solution for stopping the compiler from disabling interrupts for delay functions(
#use rs232(BAUD=9600,UART1,ERRORS)
#int_xxx
void xxx_ISR(void)
{ ...

There is a similar problem with some 16x1 LCDs. Maybe it has something to do with that.
Some 16x1 LCDs have to be configured as 8x2. Take a look at PCM_Programmer's driver for 16x1 LCDs (flex_lcd_16x ...

Do you think it's possible to port that project to CCS?
Like how many hours will it take for a beginner who knows some stuff about CCS C but nothing about C18 C?
Is there any info on porting code fr ...

I too have searched about this a couple of weeks ago and came across [url=http://direction.scene-double.com/2008/07/08/usb-msd-bootloader-for-pic-microcontrollers.aspx]the scene double project.
I was ...

I'm not an expert but I suggest you test with a simple setup.
Let modbus library use hardware UART.
Use ASCII mode and if you can, use another 485 receiver and a PC to see whats going on the bus.
...

i am using MAX3843 to use 485
here is schematic
...
and in code i have defined in this way

#define MODBUS_SERIAL_ENABLE_PIN PIN_B12 // Controls DE pin for RS485
#define ...

I get those warning too. I don't know exactly what problems they might cause, but my circuit works.
BTW, I use hardware UART and ASCII mode. I don't know if that makes a difference.

then some thing like this will work?
modbus_read_holding_registers(0x08, 4000, 1)

Yes. But make sure the register address' base is correct. You may have to use 0x4000. Your spec sheet didn't men ...
