sfyris posted a comment on discussion Compiler Problems
why? It shouldn't be. Like 12, 45, 123, 4323 etc, 00 it's only a number, it's zero, what's the difference when it is written 0x00 or 00 or 00000 or 0000000 etc.

Hello friends. Look please at the following pictures. When I pass a 00 as parameter in i2csend as plain decimal number i have a compiler error. When i pass it as a hex 0x00 all is ok.

Interesting. Thanks a lot

And from me all well setup. Although I had to uninstall the old one

Yesterday tried this with a 12f675. It works! no need for pullups, just turn off the chip's option_reg.7 ! ;Chip Settings #chip 12F675,4 #option explicit dim p_w as byte ' Define I2C settings #define I2C_MODE master #define I2C_DATA GPIO.4 #define I2C_CLOCK GPIO.5 #define I2C_DISABLE_INTERRUPTS ON #define I2C_BIT_DELAY 20 us #define I2C_CLOCK_DELAY 30 us **OPTIONREG.7 = 0** Do Forever for p_w = 0 to 255 repeat 100 I2CStart I2CSend p_w i2cstop wait 10 ms end repeat next Loop

Any support (libraries or code) for SX1278 Lora programming? Simple code please, as to make it transmit or receive mode in full power and how to reflect a pin ON or OFF from transmitter to receiver

well rowdy (if you are still there) there is a simple method to try. Assume for the 12F675, a trimmer on each pins AN0 and AN1 as voltage dividers and the code bellow gives you good comparator results about the difference of the two inputs. Just pick an_diff and treat it as you wish in your code. You can check this even with a simulator, put one oscilloscope channel on an output pin and give it pulses of an_diff milliseconds width (figure it on my attachment). P.S. Trying readad(AN0, AN1) does not...

Yes very nice warning. Thank you for your offer, I appreciate it.
-
Anobium the 3rd case is more likely to my opinion with the exception to add the word "maybe" in the warning. eg : "Internal clock source maybe does not support specific frequency" or more specific "Warning: Internal clock source maybe support specific frequency for simulation primitives but not in real chip".

Here I wish to show with the 1st attach image an issue with 1 and 4 MHz configuration which is changing the wpu4 and wpu5 behavior following with solution in 2nd attach image. Don't know if this is elsewere in forum solved, but took 3 days to me to solve so I desided to post it to help others.

Yes sure it is usefull when writing a variable wrong accidentaly, without this option compiler assumes the wrong variable as byte and continue using it without warning. In small programs someone can easy observe what is going wrong but in bigger ones things go hard when this happens.

Oups sorry Anobium, just forget to remove the #defines, its ok now it works, thank you. But anyway why is this necessary, that shouldn't be. And specially to only one var, the SERVO_STEP. Why not for the others?

nothing hard in my code Anobium. Just a general variable declaration at the start and then the code. Dim xcenter, ycenter......etc etc as word etc etc Until now I had no issues declaring general vars and then use them inside of subs. Its a programming rule they are known elsewhere in the code. Why I should declare them again when use in subs?

yes sure, in bla bla session of my post it is supposed that these vars are declared as words. But anyway from now on it is known that line must be out of any sub or function

Well, as for the sim issue, one solution I found is going in the settings of the chip and set the frequency by hand. Ok a little tricky but it works.
-
Ok XTAL issue solved, NO NEED FOR CAPACITORS. When I put them back chip goes down to 4MHz. The position on the breadboard seems not critical (to me anyway). Now remains the other issue, that with the sim and the ext rc osc...thank you Mr Roper. And yes you have right, GCB sets by itself the configuration, no need for derivatives. What a lovely language.

back to reality...but with something different now. In attached foto you see my ext connection of a crystal oscillator. A 20MHz crystal, two capacitors of 47p....bla bla...at pins 13-14...Nothing simple like that. But the 16f887 don't seems to run that fast. It seems to go at 4MHz internal osc. And the code (the # symbol is gone at copy - paste don't know why, it is there in the code) chip 16f887,20 config OSC=HS bla bla bla.....

No in real I dont tried yet. Only in sim

no option of external oscillator is working Tried any

8MHz, the internal osc
-
ok I tested it on my adafruit with a 16f887 pic and it worked. But why is its drawing so slow? is that normal?
-
no error for the first (0.5) but for the second (0.05) it stops compile with the message "Error: Invalid PWM Frequency value"
-
And finally, is there any solution to have 50Hz with CCP1? for 500Hz I found that this worked! define PWM_Freq 0.5 but not this define PWM_Freq 0.05 for 50Hz
-
yes it worked but it would be more comfort to me if its possible to make it directly from GCG
-
Trying to load the demonstration I get this error message
