Part Number: BQ40Z80EVM-020
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Hello,

I want to use the GPIO in the EVM using Bqstudio, what can be done, and how to check if it's happening or not?
The bqstudio has GPIO and flag setup in the settings, how to proceed further with its testing?

Hi Manas,

I believe that after configuring the pin the GPIORead() and GPIOWrite() commands can be used to test the functionality of the pin.

Hi Anthony,

Yes, I have seen that and implemented a few of them, I wanted to try other configurations and was clueless to proceed ahead. So I wanted to know what functionality it has and how to add for example charge and discharge through GPIO, and which pins should I configure to achieve it.

Hi Manas,

Can you please go more into detail about charging and discharging through the GPIO? This will give a better idea of what is trying to be accomplished with the GPIO pins.

Regards,

Anthony

Hi Anthony,
I wanted to check if we can enable the CHG_FET and DSG_FET through the GPIO pins and what configuration needs to be done for it.
