使用24FJ64 GA702的电路一些I/O不工作

我用了702个设备，一切都很好：你能显示你的代码吗？

    I used a 702 device and everything looked good:
can you show your code?

这里是我的代码的短版本（变量和；为了简化），其中包括“xc.h”int main（空隙）{Trasi= 0x01；Tra***＝0x017；nop-（）；ANSA= 0x04；aSb= 0x04；LATB＝0；LATB＝0；LATA＝15424；LATB＝48192；//48192 I2C1CONL= 0x2000；//禁用I2C，因此I/O引脚可获得I2C2CO。NL= 0x2000；LATB＝0x3C40；LATA= 0x14；LATBITS.LATB8＝1；//这开启输出以打开FET以驱动7SEG LED返回0；}有许多I/O，我似乎不能驱动。B8、B9、B10、B11、A4。1或2可能是一个坏的焊点，但没有办法5都是坏的。我还焊接了第二个电路来验证这不是一个物理问题。谢谢。



      以下为原文

    Here is the short version of my code (variables & such removed for simplicity)
 
#include "xc.h"
int main(void) {
    TRISA = 0x01;
    TRISB = 0x017;
    Nop();
    ANSA = 0x01;
    ANSB = 0x04;
    LATA = 0;
    LATB = 0;
    LATA = 15424;
    LATB = 48192; // 48192
    I2C1CONL = 0x2000; // disable I2C so I/O pins are available
    I2C2CONL = 0x2000;
    LATB = 0x3c40;
    LATA = 0x14;
    LATBbits.LATB8 = 1;  // this turns on output to turn on FET to drive 7-seg LED
    return 0;
}

There are a number of I/O that I can't seem to drive.  B8, B9, B10, B11, A4.  It is possible 1 or 2 are a bad solder joint, but no way 5 are all bad.  I'm also soldering up a second circuit to verify it's not a physical issue.
Thanks

M，为什么要用十进制数？此外，您需要在代码底部有一段时间（1）循环，或者PIC会一遍遍地重置，行将（简单地）还原为输入…



      以下为原文

    M,,, why use decimal numbers?
Also, you need a while(1) loop at the bottom of your code, or PIC will reset over and over and lines will (briefly) revert to inputs...

“while”循环不是一个因素。我试过了。我也跟着调试器一步一步地走着，同样的结果。对于十进制数，你会得到一个笑声。我用Excel电子表格计算数字，Excel用十进制显示所有的东西。而不是重新翻译回HEX，我相信Excel的答案。有效点，我会仔细检查。但这些是我的“显示”模式设置。我可以确认显示器关闭了。这是后面的线（3以下的小数）后的I2C设置“打开”显示器。这就是我看到的部分显示（不是所有的片段都打开），而不是所有的数字都可以显示。我可以看到7个片段中的4个，只有4个数字中的2个。



      以下为原文

    The 'while' loop is not a factor.  I tried that.  Also I walked it step by step with the debugger and same results.
 
For the decimal numbers, you'll get a laugh.  I used an excel spreadsheet to calculate the number, and excel displayed everything in decimal.  Rather than re-translating back to hex, I 'trusted' excel's answer.  Valid point, I'll double check them.   But those are my 'display  off' mode settings. And I can verify the display is off.  It's the later lines (3 below the decimal #'s) after the I2C settings that 'turn on' the display.  And that is where I see a partial display (not all segments turn on) and not all digits can be displayed.  I can see 4 of the 7 segments, and only 2 of the 4 digits.

15424＝0x3C4048 192＝BC40OK！

    15424=0x3c40
48192=BC40
 
ok then!
