Electronic – History of the MSP430

historymicrocontrollermsp430

This question crossed my mind today.

What is the history of the MSP430? When did it start, what did it evolve from, why was it made (i.e. what goals was it trying to achieve/what technical limitations with current uC was it trying to address), and why is it called the "MSP430"?

An internet search only revealed this power point, which doesn't say much.

There was a little-known predecessor to the MSP430 series in the early 1990s, which was the TSS400 "uPower Programmable High-Precision Sensor Signal Processor". It had only an 8-bit processor, and the ROM contained an interpreter for a language called SMPL, so it was not intended that it be customer-programmed in machine language (or C, or any other "normal" programming language).

While the TSS400 showed promise, ultimately customers wanted a more powerful processor, and the MSP430 was the result.

Oh, duh, I didn't read your code carefully -- your send SendLcdByte is wrong:

    void SendLcdByte( unsigned char command_0_or_data_1, unsigned char command)
{
    SendLcdUpperNibble( command_0_or_data_1, command);
    // send the lower nibble next
 // AS WRITTEN:
    P1OUT = (command & 0x0F) | (P1OUT & 0xF0);
 // SHOULD BE:
    P1OUT = ((command & 0x0F) << 4) | (P1OUT & 0xF0);
    Strobe( command_0_or_data_1);
}

You are not waiting for the ADC to finish the conversions. You would have to do something like this:

 for (;;)
{
  ADC10CTL0 &= ~ENC;

  while (ADC10CTL1 & BUSY);                 // Wait if ADC10 core is active
    ADC10SA = 0x200;                        // Data buffer start
    P1OUT |= 0x01;                          // Set P1.0 LED on
    ADC10CTL0 |= ENC + ADC10SC;             // Sampling and conversion start
    __bis_SR_register(CPUOFF + GIE);        // LPM0, ADC10_ISR will force exit
    P1OUT &= ~0x01;                         // Clear P1.0 LED off
 }

}

You should read the user guide - chapter 20 (I think) ADC10 and look at the code examples on ADC10 with DTC
