IIC Pull-up
Analog Input Potentiometer
Optional Jumpers For Various VDD And VSS
J30 - Buzzer enable jumper BUZ_EN
J31 - IIC Pullup Enable Jumpers IIC_EN
J32 - Potentiometer Output Selection Jumpers POT_EN
Figure 8-23: Potentiometer Output Selection Jumpers POT_EN (J32)
The DEMOJM provides external pull-up resistors for SCL and SDA lines,
enabled by installing the corresponding jumpers on J31. By default both
jumpers are installed.
The DEMOJM provides an easy access 10KOhm potentiometer whose output
may be connected to PTD1 and/or PTB2, selectable by J32, POT_EN.
The DEMOJM provides 5 jumpers, J22 through J26, for different VDD and
VSS connections on the bottom of the board. By default, they are not
