Developing With eZ430-TMS37157
The eZ430-TMS37157 can be used as a stand-alone development tool. Additionally, the
eZ430-TMS37157 target board also may be detached from the debugging interface and integrated into
another design. The target board features an MSP430F2274 and most of its pins are easily accessible.
The pins are shown in
Figure 2
and described in
Table 1
and
Table 2
