    Re: Unable to execute MPASMX

    For the last 20 or so years I have enjoyed using PBP for work and at home for my own projects. I would hate to see it die a slow death. So far it has been very useful with some of the newer PIC's I...

    Re: SERIN2 WAIT problem

    I have to ask, What is the serial input port connected to? Does the receiver have a CMOS output meaning it can sink and source voltage for the input pin? If it is an open collector output from the...

    Sheldon, The only statement required for PBP is the "DEFINE LOADER_USED 1" at the top of the program.

    Sheldon, Here is the source directory I use here. The forum does not allow files bigger than 1M so I can't send you the x0.11.2 executable.

    Re: Tiny bootloader and pbp

    Sheldon, Where did you get the .ASM file for the processor? Looking at and comparing the two different files the one that you modified is rather old from 2016.01.15 revision 5 and the one I sent you...

    Re: Tiny bootloader and pbp

    Sheldon, You don't have to compile it as the source ia already an .ASM file. It only needs to be assembled with MPLABX. That will give you an .HEX BootLoader file that needs to be FLASHED into the...

    Re: Tiny bootloader and pbp

    Sheldon, Just modify this file extension from .txt to .asm. Then modify for the frequency and chip config and then assemble with MPLABX to get the .hex file for flashing. Then use TinyMultiBootLoader.

    Re: Setting 8Mhz clock speed on PIC16F684

    Yes, That is correct. The PAUSE command is based on the OSC frequency. If you had an 4 Mhz. crystal connected and told PBP that the OSC was 8Mhz. the PAUSE command would give you 2 times the value...

    A rather interesting read Ioannis.

    Looking at your code I do not see the IRQ routine "ClockCount".

    Re: Customizing the DT_INTS-XX.bas Instant Interrupt

    I din't see where you are clearing the individual IOCCF flag bits before or after the interrupt?

    Re: Customizing the DT_INTS-XX.bas Instant Interrupt

    Bo, I have NO issue using it with IOC or INT. I would make sure ALL registers are set for using IOC. I have attached the page that tells of all the resisters affected.

    Re: Value of temperature

    I believe you are going wrong by not subtracting the zero degree C. offset before you calculated the final value of quanta. Here is what I calculate:

    0 degrees C. = 273.15 degrees K.

    Re: 18f4431 PORT.5 Problem Large automated machine

    I'm not sure the config strings are right. After looking at the .INC file in MPLABX it says the config bits are to be constructed such as:

    Please,Please explain how you are going to get a single CD14536 to support 4 independent frequency's. I must be REAL stupid.....

    Instead of using the PORTA.7 directive, why not use the LATA.7 directive? You maybe seeing the Read/Modify/Write problem. Try it....
