    Re: First attempt at using Preprocessor

    Not sure how this got from CAN to Bluetooth, sorry Bob!

    I've been using the HM-10 BLE module on the Arduino recently. Quite easy to use with the IPhone/Ipad. 2 I/O plus Vcc/Gnd. I haven't tried...

    I2C Lcd Print & Owrite

    Afternoon all,
    I have a PIC-DIP40 board set up with an I2C backpack using George's I2C-LCD code and a DS18B20 temperature probe. The DS18B20 is hardwired to RC3 (I2C_SCL).

    Testing Bits of a register.

    Hi all.

    I am trying to convert this C statement into basic. "while (SPI_ReadStatus() & 0x54)". 0x54 in binary is 0101 0100. I need to test bits 2, 4 and 6 any if any of the bits are set, then...

    Hi Stephen, thank you for your code. Am I right in saying you used that for a DIP40 package?

    Hi Matty,
    I don't think the Code Configurator works with DSPIC33, unless there has been an update since I last used it.
    Unless you really like a challenge, I would avoid using the SPI with DMA if...
  14. Re: Replace the PRINT command to use I2C backpack on 1602 LCD

  17. Re: Input Capture only working with one pin at a time Help!

    I'm thinking that you would be better off using a Dual QEI DSPIC or similar.
    The only problem with input capture/interrupt pin is that you will be spending a lot of time in an interrupt.

    You can...

    Referencing register sections with multiple bits in one command would be a nice compiler feature though.
