    Re: Goodbye

    You and I are on the same wavelength. I remember your name from previous posts I made when I was a PIC user.
    I think MikroElektronika would be the way to go. They have the best development system...

    Re: Goodbye

    Thanks for all your replies. I wasn't going to come back but I was curious if anyone was agreeing with me...and some did.

    I just bought 6 Arduino UNO boards for $12 (CAD) each, all taxes and...

    Goodbye

    Just wanted to say goodbye and thank all the people who helped me with PBP the last 10 years. I'm pulling the plug on it and PIC microprocessors and going over to the t other side: Arduino hell.

    Re: more i2c and mcp23017

    Despite the superiority of PBP and Mecanique IDE, working with the i2c commands is a bear! Struggled for a week on it, still no go. Went back to Arduino, and still cursing at all the syntax. ...

    Re: more i2c and mcp23017

    I put a label at the end of my i2C write statement to flash an LED if there is no acknowledge from the chip.

    there is NO acknowledge...the LED is flashing. So that's a result I will work with. ...

    Re: more i2c and mcp23017

    Yeah, I saw that but $12 didn't work either. Output just won't go low. I measure 3.5 volts or so with my DMM on all GPA pins.

    more i2c and mcp23017

    I have a bunch of LEDs with anodes tied to Vcc through resistors. The cathodes are tied to the outputs of an MCP23107 port expander. I'm using the same setup I had for Arduino that worked, so I...

    inverting all bits in a byte

    How do I invert all the bits in a byte?

    Eg %011010110 would become %100101001

    I assumed, then read it was by using the tilde (~) function but I'm having trouble using it in code.

    eg if I had...

    Re: need help with PBP, I2C and MCP23017

    Thanks Richard. MELabs also told me it was $40 for address. That was the problem! That and the fact my outputs are active low and I was sending active high bits.

    Re: need help with PBP, I2C and MCP23017

    Address bits are connected to ground. for Arduino I could use address $20 or 0 to access, the latter if I used one of the libraries.

    need help with PBP, I2C and MCP23017

    I've decided to abandon 5 months of learning C++ so I could use Arduinos and going back to the superior PBP and PIC MCUs. Having said that, Arduino had the most fantastic libraries which made I2C...
  16. Re: First use of i2c from parallel output processing

    I basically want to light "everything" in as many patterns as possible: light chasers, all 16 at time, blinking, fading (maybe if I use PWM), rotating, etc, etc. I want individual control over 110...
  17. Re: First use of i2c from parallel output processing

    It's been a while since I was here 'cause I was really into getting the Arduino/AC matrix going. AC matrix with triacs or SSRs does not work. The matrix part works but there is too much leakage...
  18. Re: First use of i2c from parallel output processing

    I made a model, using mono-color LED, and I2C port expanders. Worked extremely well.
    I then made a model using RGB LEDs, again with port expanders and wired in a matrix so I could turn on just the...
  19. Re: First use of i2c from parallel output processing

  20. Re: First use of i2c from parallel output processing

    My wife also does 1/12 scale "dollhouses" and has about 20 different scenes. And I light some of her work as well. Wife has won a number of competitions and has been published 1/2 dozen times.
  21. Re: First use of i2c from parallel output processing

    Thanks for the reply. I've done more research, looked at Arduino examples (I have lots of Arduino, but PIC seems better because of the great IDE and PBP!)
    The PIC will be talking directly to the...

    Re: Decline of PicBasic ?

    I just went through a process of selecting between Arduino, PBP/PIC, and Raspberry Pi. I have hardware for all and have used each one for a project.

  23. First use of i2c from parallel output processing

    I did a project where I used a PIC 16F887 and used all the ports, A,B,C, D for outputs to triac boards. Lots of wires.

    Now I want to do another similar project using I2C protocol, conversing with...

    incrementing 16 bit timer value

    I have TMR1 loaded with $FC7C, using the commands TMR1H=$FC and TMR1L=$7C.

    I was hoping to make this one variable like T1Val=$FC7C so that I can increment or decrement this timer value. Can this...
