The F28P55x LaunchPad includes two headers, J12 and J13, which are used for connecting linear or rotary incremental encoders. These headers take 5V input signals that are stepped down to 3.3V and wired to the F28P550SJ9 MCU. These signals are connected to the eQEP modules on the device when switch S5 is set appropriately, see Table 3-6. Each header has the EQEPA, EQEPB, and EQEPI signals available for each eQEP module (1 and 3) as well as pins for GND and 5V.
