USB2ANY: PULL UP RESISTOR

Adhithiya N

Part Number: USB2ANY
Other Parts Discussed in Thread: LMP92066, , LMP92066EVM, MSP430F5529

I am planning to use USB2ANY to communicate with LMP92066 via I2C. The datasheet says that there are switchable pullup or pulldown resistors in the USB2ANY board. How to control the switch and what is the value of the pull up or pull down resistor.

Adhithiya,

The USB2ANY is only intended to be used with the LMP92066EVM using the GUI software provided. You can find links to the EVM user's guide and GUI in the following product folder:

https://www.ti.com/tool/LMP92066EVM

I don't think the EVM GUI has any switches to control the GPIO pullups. However, the USB2ANY uses an MSP430F5529 microcontroller and its GPIOs have pullups that are typically 35kΩ (min/max is about 20kΩ to 50kΩ).

Are the GPIOs of I2C programmable?(It is specified in the datasheet of USB2ANY- screenshot attached). How to program the GPIOs of the I2C pins.

Adhithiya,

There is not very much documentation on the USB2ANY to create your own custom controls. Again, the USB2ANY was designed for controlling TI EVMs and EVM GUIs, and because the LMP92066 has an EVM, the USB2ANY can be used to control it with the GUI. Because of this, we generally will not provide support for the USB2ANY outside of using it to control the EVM through the GUI. We do not have the ability to support the USB2ANY for any other development.

However, I was able to find some information that might help you in programming up the USB2ANY in the following:

Beyond these posts, I'm afraid there may not be much more information to help you in specific programming questions.
