Texas InstrumentsTPL0401EVM开发套件和工具

The TPL0401EVM is designed to operate with the Texas Instruments LaunchPad (MSP-EXP430G2). The TPL0401EVM comes with a preprogrammed MSP430G2553 microcontroller which is to be inserted in the DIP socket on the LaunchPad. The LaunchPad can be purchased separately at http://www.ti.com/launchpad
The TPL0401EVM has three different evaluation modes:
Mode 1 – LED mode – This is the standard mode the TPL0401 comes up in when powered up. In this mode the TPL0401 devices are used to control the color mixing on the RGB LEDs. The DPOTs are used to set the current limit for the TLC59108 LED driver. This mode is an auto run mode that does not have any GUI control. The flashing lights and color mixing is controlled by the keys on the board and other TI products on the board.
Mode 2 – Adjustable voltage reference mode – In this mode the TPL0401 is used in conjunction with an LMV321 op amp as an adjustable voltage reference circuit.
Mode 3 – Variable gain mode – In this mode the TPL0401 is configured as part of a variable gain non-inverting amplifier. The gain of the amplifier can be controlled by a digital interface. This mode can be used to evaluate the bandwidth of the TPL0401
