    JMLB got a reaction from SouLSLayeR in Problem with high impedance state   
    Are you connecting to the launch pad? is pin 1 and 0 p1.1 and p1.0 on the launch pad?
    P1.0 on the launch pad is connected to an led and 1.1 is connected to the transmit of the uart. maybe removing the jumper for rtx and the led (assuming you are using a launch pad)
     
    just a shot in the dark here.

    JMLB reacted to RobG in How to safely connect a pot to the ADC   
    See the family user guide.
     
    Simplifying things, during sampling, a switch for the selected channel is closed and charges tiny capacitor (~27pF) and that is the only current flowing through this circuit, we are talking uA here over the period of few us. Once the cap is charged, there is no more current flowing. Then that switch is opened and another closed, one that connects the capacitor to a comparator. Comparator then compares capacitor's voltage to a reference voltage which is connected through resistor network (basically a DAC.)
    When the whole converting cycle is done, SAR's value is written to memory register.
     
    How SAR works?
    For example you have 15V voltage reference and a 4 bit SAR with a ladder of resistors that can output 0-15V, bit0 1V, bit1 2V, bit2 4V, and bit3 8V. It's output is connected to a comparator. S&H capacitor is also connected to a comparator and is charged during sampling cycle to 7V.
    Converting cycle begins and bit3 is turned on, comparing 8V to 7V, because it's bigger, bit3 stays off, next bit2 is on and 4V is compared to 7V, since 4V is smaller than 7V bit2 stays on, then bit1 is set, comparing 6V to 7V (6V because bit2 is still on 4V + 2V.) 6 is less than 7, bit1 is on. Next bit0, 7V is not more than 7V, bit0 is on. End of converting cycle, SAR register is 0111 and it's written to mem register.
     
    How many cycles this whole process takes?
    You must have enough cycles to charge the capacitor (sampling time,) the bigger output resistance of the measured circuit, the longer it will take to charge it. This usually takes few us, but sometimes when you have dividers with mega ohm resistors, it may take several tens of us.
    The comes converting, one cycle for each bit of resolution so 10bit ADC will require 10 cycles.
    Figuring out sampling time is important because it will introduce error if it is too short and the capacitor is not charged to the input voltage.

    JMLB reacted to TheDirty in SD card information   
    You should just need to update the hardware routines, which are all in diskio.c It's not that hard, but I'm basing the assessment on people having a decent knowledge of C and SPI. I've done it for a few chips and the flash size has been between 11 and 16k with RAM usage about 1.5k for this library, so it's not going on a smaller MSP430.

    JMLB reacted to RobG in UART, RX problem   
    I think that the culprit here is the actual code.
    Even in my setup, when I send one or two bytes one after another, all is fine. When I send more than two, things get messy.
    I have verified with loop back that my computer side works fine, but when I do loop back through LP, I loose some bytes here and there. What I can suggest is to hook it up to the scope or logic analyzer and see what's going on. I will be looking closer at the code I am using to see what's causing issues I am experiencing, maybe that will be helpful to you too.
     
    EDIT:
    Also, how about removing the chip, connecting the phone through MAX232 to the LP board, putting back jumpers, and then using LP's USB to connect to the computer? It would verify that LP "sees" proper levels.

    JMLB got a reaction from bluehash in Redistribution of the Stellaris DSK files   
    I have contacted the TI support they do have a legal section. I tried contacting them threw the stellaris website but I didn't get an answer. When i went threw TI support I got an answer after a few days. They said they would get some one to reply on the forum as well. As far as what i got as a reply basically if i am releasing it for personal use and not as a open source project then it should be ok. They also stress that it was not legal advice and I should probably refer the thread linked by Brandon and contact a lawyer for any thing beyond that.

    Hi,
     
    i even tried soldering it into existing holes - didn't work. My TEXTOOL clone is no
    TFXTDOL (i got these too, but not 20 pin-type) but a clone with "3M" marking.
     
    As soon as i get machined 20 pins sockets, i will again solder one into my launchpad
    and use this construction, an ZIF addon-board for Launchpad. Hopefully also the
    new Launchpads will arrive (i ordered some, as i though i might have damaged
    mine, who knows...)
     



     
    I did this without any professional equipment, so the results are not that nice.

    JMLB reacted to RobG in 3.3V LCD Displays with 5V back-light   
    Most of 3.3V LCD displays come with 5V back-light and one way of powering it in such displays is using step up converter. There are many available, like LT1300 from LT or MAX756/856 from Maxim.
    For my display, I am using LT1300 which requires 4 additional parts only:
    L1 - 22uH inductor (10uH-22uH will work)
    C1,C2 - 47uF (47uF-100uF)

    JMLB got a reaction from bluehash in My first evalbot Project   
    this isn't a msp430 project but I am posting it in the other microcontroller since some of you use the evalbot and might be interested.
     
    I finally got my evalbot working the way I wanted it to and I can start working on other things. I wanted to share my progress if any one was interested. It's mostly based off the LWIP example but I try to explain every thing I am doing. Its a 2 parter I am not a very good writer and English is not my first language (go easy). Also I don't have any place to host the files. But if any one wants my projects I can send them.
     
    Basically, I load a web page off a USB drive. the web page has some javascript to detect if you are using the arrow buttons. It then calls the appropriate CGI function to drive the robot
     
    I strapped a wireless router on top to the robot is fully remote controllable. with no wires. Its allot cooler that way.

    JMLB got a reaction from gatesphere in Arduino for the launchpad   
    I saw this on Hack a day in case some of you don't read it

    Just a thought but we could also build on the arduino IDE and ship it with mspgcc but then you loose allot of features like debugging.
     
    I also think it should support what ever the launch pad supports.
     
    I am suggesting something like this based off the arduino

    LaunchPad |--------------------------------------| libraries Hardware |--------|--------| |--------|--------------------------------| LCD Servo ect MSP Core | |-------------|-----------| | LCD.c/h Comon GCC ccs Our own wrappers for essetial code... (MSPhere?) | | | IDE idependant code GCC MSP STD CSS MSP STD
     
    just to give a general Idea. we could have empty project configured for all the ide including the right paths and files ect
    I think some thing like that would make a nice little SDK and every one can contribute
