And I remembered why a single #ignore_warnings 202 line wasn't acceptable in the first place without an #ignore_warnings NONE; 'cause I want to be notified about all unused variables except rs232_er ...

Mark:

RS232_errors is a variable that holds that USART status.... ERRORS is the directive for the #use RS232 command....

If removing this annoyance is worth one instruction word, add the following early in your program:

rs232_errors = 0;

This is one of the other ways to make this error go away....

Timer0 prescaler can only be set to Divide by 2 or more so the minimum is
RTCC_DIV_2 i.e. divide by 2

So true about the prescaler.... but RTCC_DIV_1 *is* valid.

But if PSA (T0CON:3) = 1, ...

This chip is nice and simple, hardly needs a "driver".

All you need to do is:

// SPI MODE 0,0 is set up earlier

DAC_CS = 0; // Drop chip select

spi_write(dac_ms_byte);
spi ...

No I can not get to the wile loop after printf with a breakpoint.

To get around this problem, just put a "dummy" instruction after the printf, like maybe

i=0;

you can set your breakpoint ...

Will:

If you believe they're all the same, simply buy the cheaper parts. But I'd keep my resume updated if I did that.... Laughing

Microchip's website specifically states that the LF parts are tested to different specs to get lower voltage operation. They also say that the dies between the two are identical - so they *should* pr ...

This is where I found it (old data sheet):

DS40300B-page 139

Some of the newer parts have an OSCTUNE capability - these parts have been around for a while - look at some of the newer ones. Th ...

From the 628 Data Sheet showing the min - nominal - max for INTRC:

4 INTRC Internal Calibrated ER 3.65 4.00 4.28 MHz VDD = 5.0V

For reliable async comms with, for example, 10 bits, you're a ...

There, you and I part ways. My philosophy is "get the current code right before you add any new features." - Kyle

There are levels of "right", and as the system gets more complex, you have to star ...

These two tools and the device data sheet should make the fuses fairly clear.

Emphasis added - Agreed, read the data sheet over and over and over and over....

Also, with a little time to look ...

I was just about to post that when I changed mine to int16's, I got the same "error" - so glad you've got it now.

I agree with the other guys - it would be nice of the float printf were cleaned up ...

Kyle:

In your latest code, I see:

///////////// Global Variables /////////////
signed int16 glTemp[tempsensorenumnum];

Is this right? I thought you wanted int32's?

By ...

The reason I am "guessing" is that I haven't built a project with the 629.
CCS can call the fuses anything they want, and I would think they used INTRC to maintain consistency with o ...
