Hi,

I have an APP012 board, but I cannot find any information here. Could you provide its user's guide on the web site? Thx.

Hi,

I wanna define a structure from the address 0x0080 using c18.

These are my codes:

#pragma udata MeasureData=0x0080
struct
{
unsigned int Ia;
unsigned int Ib;
unsigned int Ic;
unsigned int Ig;
unsigned int Inm;
unsigned int In;
unsigned int IIt;
}MeasureData;

But the MPLAB outputs a error when BUILD ALL

Error - section 'MeasureData' type is non-overlay and absolute but occurs in more than one input file.

Please give me a hand, thanks a lot.

Thank you, you are so nice a guy.

I found the reason last night. The J6 connecting causes RB0 low. My carelessness brings you a trouble, sorry.

I change R7 into 470 from 4.7k to resolve this problem.

I feel so glad to join this bbs although I am not in Taiwan.

I met a problem:

I use PICDEM 2 PLUS and write a INT interrupt test routin as follows. But I cannot go into the interrupt routine. Please give me a hand. Thanks a lot.

# include <pic.h>

void InitIO (void);
void InitInt (void);
void interrupt Isr (void);

void main (void)
{
InitIO ();
while (1)
{
InitInt ();
if (RA4==0)
PORTB=0b00000010;
else
PORTB=0b00000100;
}
}


void InitIO (void)
{
PORTA=0x00;
ADCON1=0b00001110;
TRISA=0x11;
PORTB=0x00;
TRISB=0b11110001;
}

void InitInt (void)
{
INTEDG=0;
INTE=1;
GIE=1;
}

void interrupt Isr (void)
{
INTF=0;
PORTB=0b00001000;
}

Most PIC ADC is 10-bit, but I need a 12-bit ADC module. Yes, pic16c77x has 12-bit ADC, but its fuction is far away from my request.

As I know, MCHP has a app note about how to use a 10-bit ADC PIC reach the 12-bit resolution. However I cannot find it from the microchip web site. So anybody has this kind of experience? Please give me some advice.

Thanks a lot.

I met a strange problem, I tuned mplab 7.01 using a mature programme. But I got a fresh error that I had never met.

Error - section '.org_1' can not fit the absolute section. Section '.org_1' start=0x00000004, length=0x0000001a

Please give me a hand. Thanks a lot.

You had better contact GREATA who is a Design House in Taibei city. The phone number is 00886-2-23456969. You may contact a guy named Gary.

The USB driver of ICD2 will be in the file
C:\Program Files\MPLAB IDE\DriversXP\ICD2_USB
in you disk, if you have installed MPLAB IDE already.

thx, guy : )

Could anyone teach me how to write the raw data into the registers of such CAN I/O Expanders? Use any programmer as PROMATE II? Or other methods?

Thanks a lot.
