    SSD1322 is ONLY SPI

    HI,

    As I said previously, I have never seen a SSD1322 driver chip Oled using I2C. The Oleds with 0ohm links to change between I1C and SPI normally use the SSD1305 / SSD1309 series ICs. My 3.1" Oled with SSD1322 does not have any 0ohm links and cannot be converted to I2C

    so I just checked the SSD1322 specification

    The SOLOMON SYSTECH SSD1322 SEMICONDUCTOR TECHNICAL DATA spec states:-

    Selectable MCU Interfaces:
    o8-bit 6800/8080-series parallel interface
    o3/4-wire Serial Peripheral Interface

    8.1.3MCU Serial Interface (4-wire SPI)
    The serial interface consists of serial clock SCLK, serial data SDIN, D/C#, CS#.
    In SPI mode, D0 acts as SCLK, D1 acts as SDIN.
    For the unused data pins, D2 should be left open. The pins from D3 to D7, E and R/W# can be connected to an external ground.

    8.1.4MCU Serial Interface (3-wire SPI)
    The 3-wire serial interface consists of serial clock SCLK, serial data SDIN and CS#.
    In 3-wire SPI mode, D0 acts as SCLK, D1 acts as SDIN.
    For the unused data pins, D2 should be left open. The pins from D3 to D7, R/W# (WR#), E(RD#) and D/C# can be connected to an external ground. The operation is similar to 4-wire serial interface while D/C# pin is not used. There are altogether 9-bits will be shifted into the shift register on every ninth clock in sequence: D/C# bit, D7 to D0 bit. The D/C# bit (first bit of the sequential data) will determine the following data byte in the shift register is written to the Display Data RAM (D/C# bit = 1) or the command register (D/C# bit = 0). Under serial mode, only write operations are allowed.
    cheers

    PS My lmsmonitor has been running all day, working great, switching between data and visualizations, on both sound files and streamed radio.

    Unable to install LMS Monitor 2020 on pCP 7.0 Beta

    @shunte88

    Any chance to use it with 7.0.0 Beta version?

    i2c-tools-dev.tcz seems no more downloadable as an extension on the repositories...

    Let me know.

    pCP 7.0 and the Mon'

    hi @seekasoul
    you won't need the dev package - you only need that to look for your i2c address

    you should be able to get going by following the install instructions and skipping that step

    configure pCP data sharing
    do the wget step
    then use the same command line as you used before to spin up the monitor

    i'll pull a 7.0.0 build together and check for any issues but hopefully we're all set

    let me know if you do hit snags, I have the code open today so I'm ready to start any type of review
    As of 17-Nov-2020 my digitized collection is (24770 hours 5 minutes) + (22 seconds) or

    Unable to make it work with pCP 7.0.0 Beta, can you help me into doing it?

    I'll get a system setup and poke around some
    Are you setup on Pi3 or Pi4?
