Pico-D4 useage of IOs 7/9/10/11
Posted: Thu Feb 18, 2021 12:20 am
Hi All,
I have been wondering about the application for the usage for these IOs on the device. Testing them individually I found that they have a default pullup of ~47k that will always be present unless you set them to output low. IO 9/10 also work with SPI as a clk or mosi. They cannot hold their IO levels during light sleep and sometimes like when I set IO11 as an output on boot, it will restart the device.
So I am wondering if anyone has had much experience with these ios and can suggest what I can/can't use them for etc. The microcontroller itself has a limited IOs so ever pin counts
Cheers,
Ryan.
