TPS65987DDJ: Read the state on input GPIO

david Laurent

Part Number: TPS65987DDJ

Hello,

We try to use the GPIO 21 as a input . We set GPIO21 to input using GPIe and we read GPIO status register 0x75 but we get nothing; It is possible to read a GPIO ?

best regards

Hi David,

Yes you should be able to but I believe you may be reading the wrong register. The GPIO Status register is 0x72, please check the data there. Byte 3 should provide the output status of GPIO 21.

Thank you,

Hari
