SoftBaugh ES449 User’s Guide 3. Power Supplies The ES449 can be operated from a variety of power supplies, depending on the options chosen with jumper J20. This chapter discusses the most common options. In all cases, MSP current can be isolated and measured via J17. -
Page 17: Single-Cell With Capacitive Charge-Pump
SoftBaugh ES449 User’s Guide The board has a 1W zener diode (D6) to protect the on-board voltage regulators against power fluctuations. Please note that most wall-mount power supplies have voltage ratings based on maximum load. It is important to obtain a power supply with an open circuit voltage no greater than 4-6 volts. - Page 18 SoftBaugh ES449 User’s Guide Coin Cell C/P Coin Cell Capacitive C/P with Coin Cell Idle Figure 3-2 ES449 Power Supply Jumper Options Page 18 of 35...

Page 23: Typical Operation
SoftBaugh ES449 User’s Guide 6.2 Typical Operation: The following graphs illustrate the SBLCDA2 and SBLCDA2Ts viewing angles for the range of V from 2.7v to 3.6v. The voltage was measured on pin 56 (R03) of the MSP430F449. This is the input port of the lowest analog LCD level (V5). The voltage is controlled by P2 on our ES449 development kit and can be measured at TP27. - Page 24 SoftBaugh ES449 User’s Guide Figure 6-4 SBLCDA2T Contrast Adjustment--Backlit Page 24 of 35...

Page 32: Lab One, Msp430 Jtag Debugging
Warning: If you have a new, very fast, or "green" PC, you may have difficulty with equivalent JTAG programmers on any MSP430 target. Obtaining a genuine SoftBaugh FETP will usually resolve these problems (as of this writing, we haven't seen a case where it hasn't yet!). -
