  1. Re: DHT11 Humidity & temperature sensor with SLEEP for 16F690

    Thanks for posting your work Roger.

    I've been wanting to experiment with a temp/RH device lately and this is enough to make it happen.
    Copied to a file before it gets lost.

    Re: MRF90XAM9A interfacing help

    Been awhile since I been here and found this post while trying to bring the same module to life.

    After a lot of reading and comparing "working" code not in PBP, I found that a lot of confusion...

    Re: OLED Display Noise problem

    You can only "see" so fast before it becomes a blur.
    Try adding a PAUSE 33 in your main loop as it is, making it 30fps, just to test if the ghost dots go away.

    Re: OLED Display Noise problem

    Hi,

    I would suggest writing to the LCD only when you need to update the display info.
    Constantly writing to it in a loop without any kind of delay may be causing the problem.

    Re: Long / short press button...but reading ADC

    I could be wrong but I have to ask about using "CALL" instead of GOSUB for the sub routines CHECK and achizitie.

    From the MCS Help section:


    I've never used it in place of GOSUB so don't know...

    Re: how to program PIC16f18313 pls ?

    Look into the PIC12F683.
    I haven't used 2.50 in a long time but that's the PIC I started with.

    Re: Monitor supply voltage of chip?

    I think a fixed Vdd to the PIC set below the "low battery" level is your only recourse with this one.
    Then a simple voltage divider to monitor the battery level with the A/D to trigger sleep mode...
  11. Re: Electrical Issue: PIC input false triggering, Signal Noise suspected.

    Hi abecker,
    The inductors should be in your controller circuit because just as your intuition suggests, you will end up with a short antenna at the input of your box.
    If you have room at the reed...
  12. Re: Electrical Issue: PIC input false triggering, Signal Noise suspected.

    Like the guys said, a stiff pullup and a cap. I would also add an inductor to keep the noise spikes out.
    You can probably get by without L2 in this diagram but added it in just in case.

    I had to do the same thing with the PIC18F14K50.
    Our entries look similar except your label is RABC_INT.

    Re: ADXL345 Accelerometer using I2C

    It looks good to me. You need to check your connections and scope it and see if you're actually talking to it.
    See post# 8 where the I2CREAD was used same as yours, just different address.

    Re: Continuous Read Op. From EEPROM

    Check out the F-RAM. Cost more than the usual EEPROM but price has dropped by around half.
    SPI or I2C interface devices, no write time delays and a trillion number of read/writes.
