How to set K60 Open Drain Output

[CaesarI]

Hello all,

I use MQX 3.8 on K60 and I want to initialize a output pin as Open Drain Output by using fopen("gpio:output"...

Therefor MQX uses gpio_cpu_configure() in io_gpio_kgpio.c.

I could'nt see how to send the parameter for setting ODE bit in PORTx_PCRyy register.

I did'nt find any define for ODE bit.

How to set ODE bit using fopen("gpio:output"...?

Best regards,

Caesar

Hi Caesar,

unfortunately the legacy "gpio" driver has that limitation (ODE bit not supported). MQX 4.0 lwgpio driver supports ODE bit.
