Please, consider this short code:

signed int8 x, y;

y = ...
x = ...
y = x - (x - y) / 8;
x = y;

Should I cast something in the formula?

I can't figure out what may be the differences of this installation versus the previous one. Mad

I figured out.

It's my fault. I included the "bootloader.h" CCS default header in ...

If you don't specify the OSC mode in the #FUSES directive, you are going to get a default and that may not agree with your hardware. MPLAB will also choose a default if it isn't specified. MPLAB al ...

If your application code hasn't changed, then what have you been
programming into the PIC for several months ? Your statements
above seem to contradict each other.

Of course my application ...

seems that everybody is happy with the actual IDE

Me, I'm not happy at all. It's the worst IDE I ever seen. The undo/redo doesn't work, sometimes it hang-up or crashs.

I use the Programm ...

Hello,

today is happened a strange thing.

I have a PIC18F4520 on a remote board and for months (literally) I programmed it through the CCS bootloader on a RS485 link.
Yesterday I formatted the ...

I want to say you a BIG thank you. Razz

It works like a charm. The problem was the bad CCS code.
Furthermore, I've just killed the CCS IDE and I'm using the PN as editor.

Thanks ...

UPDATE

So I solved the reset problem. Don't ask me how I did. I just cut & paste the same code in the same place and the reset gone away. I guess the CCS IDE is quite buggy, sometimes it crashe ...

Thank for your complete answer Ttelmah. I completely misunderstood the spi behavior and the manual explanation too.

Despite your suggestion the slave continues to reset itself.

Let's see what I ...

Hello,

I'm puzzling over a simple problem. I have two PIC18F4025 with an SPI link (SDI <-> SDO and SCK). I use spi_read / spi_write function to exchange data. The spi is working: the slave re ...

Well, let me say I'm too tired to code today... It's better I stop and go out for a walk... Laughing

Thanks for the quick answer!

Hi,

please consider this short code:

char *sPassword[9];

void main() {
int8 i;

...
strcpy(sPassword, "0000");
for (i = 0; i < 8 ...

When you say that the communication fails "after a while", is the time until failure always about the same?

No, sometimes it hangs after few seconds, others immediately.

What evidence ...

When acting as a repeater, are you still checking the transmit buffer empty bit before loading a new character from the receiver?

Nope. I do this in the rda and ext isr:

char rcv;

rcv = fgetc ...

I would use ONLY the hardware USART.

compass --> PIN_C7 (PIC) PIN_C6-->remote link
Only 1 hardware UART is needed!!(I think)

It's a great idea! But unfortunately I need to forward data ...
