    MattTheGeek got a reaction from bluehash in Half size breadboard (400 tie point) - $2.98 shipped   
    Been browsing ebay again and i came across a nice deal. A half size breadboard for $2.98 with shipping. Might be a good alternative to pololu if your just ordering the breadboard since shipping there is $4.95. (Luckily i can do will call orders from pololu :twisted: )
     
    Not sure if i'll try this deal since of above reason.

    Not mad that i didn't get anything, but to type over 5000 or even 10000 captcha for hours is horrible... Last two years were fun (Yes, trying to get a web page to load was fun)

    Tayda Electronics is a excellent source for (Very low cost) parts. However, there is a small $5 dollar minimum.
     
    You can get 125 push buttons for $5 and with $1.53 for shipping ;D

    MattTheGeek got a reaction from RobG in nanoPad - MSP430G target board   
    TI last year rolled out some really cool, extremely tiny DC/DC stepdowns. I think they might do the trick. TI also rolled out the simple switcher nano modules just a few months ago. The down side to the simple switcher is that it requires 5 basic components (3 Capacitors, 2 resistors)

    MattTheGeek got a reaction from turd in A simple ADC test   
    turd,
     
    Try this. I found out that the ADC10 had to be turned (using ADC10ON) on BEFORE setting the analog channel select bits. Also ENC should be cleared after each conversion.
     

    void main(void) { WDTCTL = WDTPW + WDTHOLD; /* Put the Watchdog on hold */ P1DIR = BIT0; //LED P1OUT = BIT0; ADC10AE0 = BIT3; /* Enable the analog channel on P1.3 (Button) */ ADC10CTL0 = ADC10ON; /* Turn on the ADC10 logic */ ADC10CTL1 = INCH_3; /* Set the sampling channel to A3 or P1.3 (Button) */ while(1) { ADC10CTL0 |= ADC10SC | ENC; /* This starts the conversion */ while ((ADC10CTL1 & ADC10BUSY) > 0) { /* Loop here while the ADC10 is busy converting or even better sleep here while waiting for the ADC10 interrupt */ } ADC10CTL0 &= ~ENC; /* Clear ENC. This must be done after doing a conversion */ if(ADC10MEM > 10) //read adc on P1.0 { P1OUT = 0; } else { P1OUT = BIT0; } } }
     
    Also take note that these lines have no effect.
     

    ADC10CTL0 |= SREF_0; ADC10CTL0 |= ADC10SHT_0; ADC10CTL1 |= INCH_0;
     
    Doing a OR bitwise assignment operation (|=) with the input of zero will have no effect, for example:

    0110 OR 0000 ---------- 0110
    It is only useful for setting bits.
     
    However, a AND bitwise assignment operation (&=) however, would work.

    0110 AND 0000 ----------- 0000
     
    I will be updating the (very old) ADC10 source code today. Thanks.

    This is the final version; I don't think it can be made any better as well as generic at the same time.
     
    All variants verified against the TI LaunchPad Eagle files.
     
    Thanks to SugarAddict for the corrections.
     
    Pro tip: make your References layer yellow (or any other unused bright color) while placing your components.

    Do you have the 32khz crystal soldered on? I find that the LFXT1S clock will run even without a crystal... If you have one installed, check if OSCIFG is set in IFG1.

    MattTheGeek got a reaction from 4pyros in How fast can a LaunchPad Power Up?   
    The MCU will start executing code in no less than 5uS (Using DCO) i believe. You can disable the emulator logic if needed and provide a separate power supply to bypass the power ramping. Wakeup from standby seems to be faster, "Ultra-Fast Wake-Up From Standby Mode in <1 ?s".

    MattTheGeek reacted to oPossum in Microchip Microstick for $18 until end of 2011   
    Usual price is $25.
     
    The Microstick is a low cost dev board for the 16 bit Microchip PIC. It has a built in programmer/debugger like the Launchpad, so you don't need any other hardware to program it. The 16 bit PIC are typically twice as fast as MSP430 at the same clock frequency, and in some very specific cases may be 10 to 100 times as fast. They have Peripheral Pin Select (PPS) that allows many of the hardware peripheral to be mapped to any convenient pin.

    If you want to play with the new DIP PIC32 (MIPS) chips, the $35 Microstick II will work with all 3.3V PIC24FJ, PIC24H, dsPIC33, and PIC32 SPDIP packaged devices. Includes 1 each of PIC24FJ64GB002, PIC24HJ64GP502, dsPIC33FJ64MC802, and PIC32MX220F032.
