Hello,

To limit current leakage from the TD1204 uart we're disabling it when not in use.
However disabling it only limits leakage to 60uA (whilst not disabling it leaks 180uA).
Is there a possibility to do this? We're using the uart in combination with a USB-self-powered FTDI chip (so it's floating when not used, hence the current leakage).

Kind regards!

Hi,

Sounds like a lot of leakage... Are you sure this is due to the FTDI chip?

Anyway setting the pin in high Z can be done by using:

GPIO_PinModeSet(gpioPortD,4,gpioModeDisabled,0);
GPIO_PinModeSet(gpioPortD,5,gpioModeDisabled,0);

Thanks Loic!

This did the trick, sleep current is back to 5uA.

Kind regards,
Giovanni.
