Software Installation Instruction 4.1 www.ti.com Powering Up the EVM - GPIO Control To • • • • • • • power up the EVM follow the steps outlined below: Install WAKEUP jumper in the GND position. Install VCOM_CTRL jumper in the GND position. Install PWRUP jumper in the VIO position. Connect the EVM to the USB interface adapter using the 10-lead ribbon cable. Connect the USB interface connector to the computer USB port using a standard USB cable. Connect a 3-V - 6-V supply from the VIN terminal to GND.
Powering Up the EVM - Software Control www.ti.com 6 Powering Up the EVM - Software Control To • • • • • • • power up the EVM follow the steps outlined below: Install WAKEUP jumper in the GND position. Install VCOM_CTRL jumper in the GND position. Install PWRUP jumper in the GND position. Connect the USB interface connector to the computer USB port using a standard USB cable. Connect a 3-V - 6-V supply from the VIN terminal to GND. Move the WAKEUP jumper from the GND position to VIO position.
Powering Up the EVM - Software Control 6.2 www.ti.com 2 GPIO/I C Controls Tab Use this page to change the I2C interface data rate and SDA/SCL pull-up resistors which are built into the USB interface adapter. This tab also provides controls for the VCOM_CTRL, PWRUP, and WAKEUP pins. Please note that the jumpers JP1, JP2, and JP3 must be removed to control the pins through the GUI. Figure 5. GPIO/I2C Control Tab Figure 6.
Other Functions www.ti.com 7 Other Functions • • • • To clear the GUI panel, press the “CLEAR ALL” button. Note that this function has no effect on the TPS65185. This function is useful to verify that “READ ALL” function is working properly. Individual registers can be read and written to using the READ and WRITE buttons. The data is displayed in HEX format. The default setting for the GUI is to update the register settings immediately after the user changes values.
