    alsenin got a reaction from ????? in WS6318 GSM Booster Pack   
    Okay. There is the yet another LP booster pack. It is for communication over GSM network.



     

    Now I have several working prototypes. PCB has couple of bugs but booster pack has full functionality. Soon, I will correct all the errors and give a full description. Schematic is in the attachment. If anyone suggest any modification or expansion of the functionality - this is a chance to introduce them into the final PCB tracerouting.

    alsenin reacted to xpg in IPv6 with the Launchpad   
    Hi,
     
    Though I'd like to share a little project of mine, which I have spend the last couple of weeks on. It's a small IPv6 stack running on the MSP430G2553 and using Microchip's ENC28J60 as MAC/PHY. I got a breakout board for the ENC28J60 cheap off e-bay (~ 7 $) and wondered if it was possible to create a small IPv6 stack using the MSP430-value line. I know that it is a bit silly, as there both are plenty of IP stacks around for the bigger MCUs and the WizNet chips (which do TCP/IP for you) are actually cheaper than the ENC28J60. But I just had to try doing it myself :oops:
     
    Now, as the 2553 only has 512 bytes of RAM I am using an external SPI SRAM chip to provide a bit more storage as an IPv6 address takes up 16 bytes and you can't get around storing around 4 or 5 of them. Currently, around 2K are used of the SPI ram.
    Currently supported are basic IPv6 things such as obtaining an address from Router Advertisments (only 1, though), ICMP ping, UDP transmission, and a very simple TCP implementation that support both server and client mode.
    The implementation is very rough (especially TCP), so I won't share it at this time.
     
    I have implemented a small proof-of-concept demonstrating the Launchpads ability to send a simple HTTP request to a web server through the ENC28J60. In order to show this, I have created two PHP scripts. One that appends a line to a file, with a time stamp, and the other displaying the file. The latter page is reloaded once a second.
    The Launchpad is programmed to send a request to the first page every time a button is pushed.
    The example takes up 11162 bytes, but does contain a fair amount of debugging strings and the size could probably be brough down a bit.
    The following short video-clip shows the thing working:


    I'll post a bit more interesting videos of Wireshark soon.
    I have a small project where I will use this, but for future projects I think I'll prefer using a WizNet chip

    alsenin reacted to RobG in Color LCD Booster Pack   
    After making my N6100 Color LCD Booster Pack, I thought that it would be better if I made it more universal by supporting different displays. So here's my v2 board, which now supports JD-T1800 display.
     
    Supported displays:
    JD-T1800 1.8" Color TFT display, 160x128, ST7735R driver (~$6.50 on eBay, $9.95 Adafruit.)
    Nokia 6110, 1.8" Color CSTN display, 128x128
    Other Nokia LCD that will work with this board (need to verify):
    6100/5100/3100
    6070/6060/6125/6101/5200
    I believe those will work too: 3200/6610/7210/7250
     
     
    Works with USI and USCI
    2 buttons and 2 LEDs (20pin MCUs only)
    JD-T1800 can be mounted in 2 positions (one will cover switches, the other will make LCD extend beyond the board.)
    Place for 2 memory chips (SRAM or EEPROM,) one with HOLD.
    Charge pump to power N6100 backlight (7660 compatible or TPS60403)
     
    Are there any other 3.3V (or 5V) SPI displays I should consider?

    alsenin reacted to oPossum in Volt/Amp/Watt meter   
    This is a simple voltage and current meter that uses the TI INA219 chip. Voltage measurement range is 0 to 26 volts with 4 mV resolution and current measurement range is -4 to +4 amps with 1 mV resolution (when using a 0.01 ohm shunt). The specs are inferior to a pair of quality multimeters, but it is a fraction of the price and shows wattage in addition to voltage and current. The Nokia 5110 display is used so the firmware could be enhanced to do simple graphing. Sending the measurements to a computer could also be done.
     
    Using the INA219 makes for a very simple circuit.

     
    The normal display is three lines with voltage, amperage and wattage.

     
    Pressing the P1.3 switch will show the 6 registers in the INA219 in hex and signed decimal.

     
    The code is written in C++ and uses templates for the LCD, IIC and INA219. Software SPI and IIC is used for maximum portability.

    Just FYI. TI recently announced about new multichanel AFE for power usage monitoring.
     
    http://www.ti.com/ww/en/more/solutions/ ... tmeter-bhp
     
    Free samples kit available.
     
    In this kit more interesting (and suitable for AC power usage BP) are ADS131E08 and AMC1100. ADS131E08 has same functionality as MCP3903 (but 8-ch onboard) and similar price.
     
    AMC1100 is a isolated amplifier, which can be powered directly from the mains through the Zener diode.

    Agree with SA, every BP should give you option for at least selection pins, SPI could be shared and fixed (UCB0.)
    Also, API should only apply to 20pin chips. This way you can use P2.x for selection and have all remaining P1.x for analog use, timer functions, etc.
    P2.0 could be LCD select (there will most likely be only one LCD BP.)
    P2.1 could be R/W, D/C, or similar feature select (FS,) not to be used for CS.
    P2.2 BP2 select
    P2.3 BP3 select or FS2 (I don't think you will stack more than 3 BPs.)
     
    P1.5, P1.6, & P1.7 reserved for SPI/I2C
    P1.1, P1.2, & P1.4 could be reserved for UART/secondary SPI

    Made this to test out the MTK3339 GPS we got through the group buy. All buyers get a free boosterpack. Thanks for making it a success.
    Code: Thanks to Robg
    Thanks to dkedr for providing the MTK3339 GPS footprint

    Features:
    - BoosterPack also acts as breakout board.
    - 3d fix led. Led goes out when a fix is obtained.
    - PPS/FIX/RX/TX/VCC/GND broken out.
    - Boosterpack connects to RX/TX of the LP. There are also solder jumpers in case you want to use some other pins to save your serial port.

    Required for v1.1
    - Battery holder- thanks dkedr.

    Below shows testing with the GPS. No MSP430 chip underneath. I'm using EarthBridge software to test the NMEA string.

    Seriously, why you think it should be a booster pack? Surface area of booster pack less then Arduino shields, MSP430 value series litle bit weaker than ATmega328 used by guys from openenergymonitor.org and in last, I doubt that sketches from emonTx would work now with Energia and LP (may be I'm wrong). Where is a profit?

    They are based on low cost analog front-end for electricity metering MSP430AFE2xx. I'm alredy used it in my own smart plugmeter and highly recommend.
     
    But actually I don't think what LP + AC usage Booster Pack is suitable for that. Because there have a deal with high voltages and there is a risk of voltage damage without the proper enclosure and isolation.

    Yes, I looking to the SIM900 for the next. There is an another reason for it - WS6318 works only in European RF band (900/1800).
    But I am so delighted with probably the smallest GSM module size and has decided to first make the booster pack with WS6318. SIM900 looks huge compared to WS6318 and probably have to abandon the built-in antenna on PCB.
