GPIO port in small PIC10F controllers is called port_b, but I was confused by the fact that in the haser file the control of the port pull-up resistors is there, but you can't add it to the program

I'm trying in the code to apply the command


port_b_pullups(True);


for PIC10F2xx and get error message:

I can't show you the code. But nothing revolutionary. The ADF4106 prescaler is used to work with the upper ranges. And of course mathematical processing of the accumulated results.

I agree, the number is very large. But modern radio communications operate on very high frequencies. Normal WiFi operates at 5,600,000,000 or so frequencies. And that doesn't fit into 32 bits...

I also thought about the loss of accuracy of int to float conversion today. I don't want to lose significant digits.
On the piclist.com site I found an assembly conversion from binary code to bcd. I ...

Sorry, PIC18F26k22

Now I'm thinking of limiting the input data to int32 and converting to float32, doing the math with float format

The program has a regular binary counter that accumulates data from the timer + adds a timer overflow and then does the averaging.
From int32 I did the conversion earlier through the itoa32() functi ...

I use a PIC18 to make a frequency meter. I get the data from the assembler insert in the program as a set of 5 bytes.
I want to convert this number to BCD-format for further display on the screen.

Thanks for the tip. Never heard of this directive before. I'm going to read and understand.

I want to write my own little bootloader and place it on top of the PIC18 memory, placing only the jump command to the beginning of the bootloader at address zero.

Thank you very much.
The final PWM configuration command in my case looks like this:


setup_ccp1(CCP_PWM|CCP_PWM_HALF_BRIDGE|CCP_P1A_A5|CCP_P1B_A4); // route pwm output to A5,A4

Thanks for your help - now the switching of the PWM pins works. Smile

Although my brain still has a slight misunderstanding of why the command works on some chips, while others must be accessed throug ...

In a project with a PIC12F1822 I want to change the assignment of the default output CCP1 to pins RA4 and RA5.
I try to use the command #pin_select:

#use fast_io(a)
