JN5189 GPIO

Viki — Sun, 21 Feb 2021 08:05:00 GMT

Hi all,

The chip I use is JN5189, the SDK version I use is SDK2.6.2_JN5189DK6, and the routine I use is Zigbee_ed_rx_on.

I wanted to use the PIO21 pin as a general GPIO output (function 1 of PIO21 is a function of GPIO) and I found that after calling GPIO_PinInit() and IOCON_PinMuxSet() to set it to function 1, I still couldn't control its output low level properly.

It is worth mentioning that the above method can control the PIO7 output high/low level normally.

I want to know how to control the normal output of PIO21 high/low level?

BR,

Viki

Hi,

I use led demo to test the pin. I only add two code to control the pin. It works.

Have a great day,

Hi @nxf56274 ,

Thank you for your reply.

I observe that you are controlling the high output level of the PIO21 pin.

As my question says, I can control the PIO21 pin to output high levels, but I can't control it to output low levels.May I ask if the PIO21 pin can normally output low level in your test?Are the chips and SDK versions you use the same as mine?

BR,

Hi,

Both are OK. The sdk is the latest.
