Are there any quantities in the universe that are known to 64 bit accuracy? That is 18 x 10^18, or roughly 10,000 x the number of grains of sand in the Hoover dam! What would a lowly micro controlle ...

@lifespeed

I also work on source code to eventually address a 48-bit DDS chip (AD9854/56 from AD). I presently use the 32-bit AD9850 for now... And althrough double precision float would be the eas ...

Thanks Douglas Kennedy...

That confirms what i said on my last post... CCS has an "autocast" function that automatically casts the variables to the smallest memory needs possible... Is th ...

Thanks PCM_programmer !!!!!

I had to add ".0" to all my values to "tell" the compiler that i need a float value.

But what i don't understand, is that i have ALREADY configure ...

Hi RF_developer...

In calculations, i always try to privilege the use of ints and double precision floats. I rarely use single precision floats.

And i wanted to use INTs for this project... but ...

1 - 0 for your HP35 !!!!

In debugging, i tried different values for my DDS.

And in editing / translating (from french to english) my code to send it here, i erased the wrong value. 34359738 is f ...

Hi....

My code is a controller for a DDS chip (AD9850).

I want to enter the RF frequency directly ("frequence" variable) and then, do a simple calculation (one multiplication and a div ...

Doesn't the code need oscillator setup ?

setup_oscillator(OSC_4MHZ|OSC_INTRC|OSC_PLL_OFF,0);

My question: Is it better to simply NOT to use "fast_io" and simply IGNORE the TRIS commands ?

I've made a LOT of assembler and still have the habit of predefining the TRIState of the PIC ...

Thank you VERY MUCH PCM programmer !!!

I had a real problem trying to activate the silicon UART on a PIC16F88.

I started to read here and there and, - BOY - , I was discouraged to see - NOT AGAI ...

Thanks a lot Bungee !!!! Your code worked !!!

Now, it's time for me to study your code to know what was my error !

Again, thanks a lot ! (I don't know why, i got a lot of problems dealing with A ...

OOps... forgot to login...

Thanks Thelma, but there is no low voltage programming mode in the F683. The "NOLVP" command is not recognized by the compiler.

Hi...

Sincerely, i do not know what to do...

It's ridiculously simple: i want to read an analog input using a PIC12F683

I made it work ! But... sometimes !!!! Most of the times, i alwars have ...

This code is a "do-nothing" code that shows how I2C works. It continuously writes data into a 24LC256 I2C serial EEPROM and then checks it's contents for data integrity. Comments are sent on ...

Here's a test code i've written about one year ago.

It is designed for 24LC256 I2C EEPROMS. The code is not optimized at all and highly commented (in French). It does read and write on the EEPROM. ...
