    Re: Forum backup

    I would like to do the same for a few forums I follow.

    Re: PCb board similar to Arduino UNO

    What you want to do is little complex

    On Arduinos, they use a usb to serial bridge ic like the FTL232, there is no built in burner. The IDE compiles and loads the hex via the usb to FTL232 to AVR...

    Re: PBP3 support for some 24F 16 bit devices?

    PBP never supported 16bit devices. The Melabs U2 programmer did support some pic24 and dspic.

    Maybe you are thinking of Proton Basic which had a 16bit version?

    I use "Adblock Plus" and don't get any pop ups. Doesn't seem to affect browsing speed and is free.

    Re: LCD with T6963C controller

    The pixels are smaller than on a charactor display.

    In the text mode you can get 8 lines by 30 charactors with a 240x64 display.

    Do you have a datasheet for the displays you are getting?

    The built in fonts are 6x8 or 8x8 pixels. So they are very small. Most users want different size fonts. The compsys1 pbp code works

  8. Re: Adding and reading byte variable from the bit array?

    Have you tried something like this?




    Myword2.5 = Mybyte1.2 'move bit 2 of Mybyte1 to bit 5 Myword2

    Myword2.7 = Mybyte1.4

  9. Re: Simplest way to write to USB stick or TF/SD card with PBP?

    I didn't know these existed. I found this document which shows that it can be interfaced in 8bit parallel, SPI or UART. Which means you can probably use a pic16 for a simple data logger. A may order...

    See the PDF file in the first post of this thread. It looks like the same module as you have. As far as folders for mp3, I have no knowledge. Maybe you can can use 0?

    Re: PWM/HPWM Stepper Motor Controller

    Henrik, I always wanted to try using the CCP module for this purpose, but not sure how to keep track of the number of pulses. Maybe feed the pwm output into a timer to keep count?

    You are making a lot of progress. Increase the current setting, just monitor the motor for excessive heat while experimenting. 12 volts is on the low side for what you are doing. For small projects I...

    It's depends on your power supply voltage and what you are driving with the motor. I would start at half of the rated current and see how it works. Yes the NEMA number is the mounting size. What are...

    Re: PWM/HPWM Stepper Motor Controller

    David, at 200 steps per revelolution the motor will run rough. Once you get it running change the dip switches on the driver to 1/8th step or 1600 pulses/rev. It will run much smoother.

    Re: PWM/HPWM Stepper Motor Controller

    This is a simple way to generate step pulses



    Count = 1

    While count < 2000 ' Send 2000 pulses rotate motor 10 times

    Latx = 1 'Output 10us pulse to stepper drive
