Figure 2 also shows the necessary power-supply connections (DVCC, DVSS), programmer/debugging tool connections (SBWTCK, SBWTDIO), and general I/O and peripheral connections (P3.1, TA1.0, CA2, UCB0SDA). When beginning any design with the MSP430 MCU, reviewing the given device’s block diagram and package pinout can provide a great guide to what is possible, as well as any constraints (such as memory size or pinout limitations).

Connecting the MSP430 MCU in any system is, in most cases, very straightforward. The first consideration should be the power-supply requirements. Most MSP430 devices operate at 1.8 V to 3.6 V, so a typical 3-V supply will work great. Connecting the JTAG to support device memory programming and debugging is also important. For MSP430G2xxx devices, there are two possibilities: standard four-wire JTAG or MSP430 MCU-specific Spy-Bi-Wire (SBW, or two-wire JTAG). Both interfaces are acceptable for programming and debugging application code. The main advantage of the four-wire mode is speed. The main advantage of the two-wire SBW mode is reduced pin-connection requirements.

Figure 3 is an example schematic thatshows the baseline connections for the MSP430G2553, as well as some examples of other connections that can be made to the I/Os and integrated peripherals.

Figure 3 shows the connections of the MSP430G2553 in a typical sensor interface application. In this example, the MSP430G2553's integrated ADC10 is used to measure an analog signal via a thermistor that changes resistance as temperature increases or decreases, and also interfaces using an I2C bus from the USCI module to an external humidity sensor. In addition, a 32.768-kHz watch crystal keeps accurate timing; two switches, along with one PWM-controlled LED, provide a simple user interface. To save power from the 3-V coin cell battery, when not in use the humidity sensor and thermistor ladder can be powered off using a general-purpose I/O (P2.5) and the internal voltage reference (VREF+), respectively.

Now that we've covered the basics and how to understand the capabilities of a given MSP430 device, let’s look more closely at the documentation and how to use it most effectively. MSP430 device documentation can be broken up into three main categories:

  • Device-specific data sheet (e.g., MSP430G2553 data sheet . ) Here, you will find anything device-specific: pinouts, block diagrams, absolute operating conditions (supply voltage and operating temperature ranges), electrical parameters and performance tolerances (power consumption, ADC accuracy, and internal clock minimum and maximum frequencies).
  • Device family user’s guide (e.g., MSP430x2xx family user's guide ) . This document contains information applicable to all devices in a family: peripheral detailed descriptions, register and bit function definitions, CPU and instruction set, power mode definitions and settings. Some peripherals included in the user’s guide will not be present in a given device, as it is intended to cover all peripherals within a given family.

sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
I rally confuse this number And equations too I need exactly help

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
