    A lot of progress has been made... So in about 2 weeks from today (Dec. 1st), I'll be releasing EasyMSP 1.0.0 RC1. I've made it leaner, lighter, and faster. (Blinky is 236 bytes...). Look forward to it.

    MattTheGeek got a reaction from GeekDoc in MSP430 Starter / Inventors kit - $34.99   
    I've been thinking of doing a MSP430 Launchpad starter kit that would provide all of the essential parts that are normally required or used. I'm thinking it would cost no more than $19.99 (Hopefully even less!) shipped... All parts are through hole. Tell me what you think.
     
    The starter kit is becoming more of a reality. The price for the kit is $34.99 (Shipping terms to be announced) and includes the following:
     
    Prototyping:
    Half Breadboard (400 tie points)
    70 jumper wires
    17 compartment case
     
    Toys:
    1x 16x2 character display (Or perhaps sugaraddicts graphic LCD)
    1x Micro servo
    1x Piezo Buzzer
    1x Photosensor (LDR)
     
    Electronics:
    10x 100 ohm 1/4 watt resistors
    10x 470 ohm 1/4 watt resistors
    10x 1K ohm 1/4 watt resistors
    10x 4.7K ohm 1/4 watt resistors
    10x 10K ohm 1/4 watt resistors
    10x 47K ohm 1/4 watt resistors
    10x 100K ohm 1/4 watt resistors
    1x Potentiometer
     
    5x 1uF Radial Electrolytic Capacitors
    5x 10uF Radial Electrolytic Capacitors
    5x 100uF Radial Electrolytic Capacitors
     
    5x 22pF Ceramic disk capacitors
    10x 0.1uF Ceramic disk capacitors
     
    5x 1N4004 Rectifier diodes
     
    1x Through hole 32Khz crystal
     
    10x Red 5mm LEDs
    10x Green 5mm LEDs
    10x Yellow 5mm LEDs
    1x 7 Segment Display
    1x IR and photo-transistor pair
     
    10x 2N3904 NPN Transistors
    5x 2N3906 PNP Transistors
     
    2x 74HC959 Shift registers
    1x ULN2803A Transistor Array
    1x 3.3V LDO Voltage regulator
     
    5x tactile switches
    1x Mini slide switch

    MattTheGeek reacted to cde in MSP430 Starter / Inventors kit - $34.99   
    3 variable regulators (or that have fixed 3.3v or 5v options) might be better.
    Lose the servo and the transistor array, they are the most expensive parts.
     
    Is it all throughhole or smd parts?
     
    And consider, running a msp430 at 3.5v would allow the outputs to be 3.3v under minimal (<1ma) loads, and 3v at 6ma loads. You can drive a blue led without need for a transistor at that point (which is why variable regulatr is better)

    Hmm A Pizeo buzzer and speaker would be a good thing to add. Maybe a micro servo motor, some small DC toy motors, LED segment display, Light Sensor...

    MattTheGeek got a reaction from GeekDoc in LaunchPad's UART at more than 9600 baud ?   
    Two ways to set the launchpad UART to be faster than 9600.
     
    The Hard way:
    Reprogram the MSP430F1. (But it might also be a hard limit inside the TUSB3410 8051 MCU. Also the program for the 8051 is stored on the EEPROM)
     
    The Easy Way (I've done this before):
    Cut the EEPROM's power or I2C data lines or simply remove it from the board. Cut the traces that connect the MSP430F1 and the TUSB3410. Do not remove the MSP430F1, as the TUSB3410 requires it for the clock source. Connect jumper wire to the RX and TX pins. Plug it in and it comes up as a TUSB3410 Virtual Com Port. Enjoy your 50 to 921.6 k baud rate. But it comes at the cost of a LP.
