LPC54608 M1pin(port1,20) cannot ON-OFF

実奥山 — Wed, 27 Feb 2019 02:06:56 GMT

tried onoff test of IO port. It is M1-pin,(port1,20).

Other pins do on-off.

But M1 pin do not on-off.

Below is a sample program.

port(1,17) do on-off.

But port(1,20 M1 pin) do not on-off.

GPIO_Clken(1); /* GPIO1 CLK enable */

GPIO_PinInit(1,17, &output_config);

GPIO_PinInit(1,20, &output_config);

oPort_sub(1,17,1);
oPort_sub(1,17,0);

oPort_sub(1,20,1);
oPort_sub(1,20,0);

Please teach me how to control M1-pin,(port1,20).

Hi 実奥山,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to the description, you want to configure the PIO1_17 and PIO1_20 as the GPIO, however, only PIO1_17 can output the low or high level, is it right?

Whether you can upload the complete sample code, meanwhile, I'd highly recommend you to refer to the gpio demo in the SDK library.
You can download the SDK library via the below link.

Thank you.

Only PIO1_17 can output the low(0V) or high(3.3V)level,

But PIO1_20 output only hjgh(3.3V).

Later I confirmed that PIO1_21 output only hjgh(3.3V) too.

I cannot control PIO1_20 and PIO1_21.

Hi 実奥山,

Thanks for your reply.
It seems a bit weird.
