The problem is i need to first detect a pulse in a digital input, then send a single pulse of 0,5 milliseconds. The delay between both events is between 2 and 8 milliseconds.
I ended up bricking my device.The hard reset on my expansion dock resulted so.I installed PutTy. Serial Communication didn't work so I had to open terminal and flash firmware.
@György-Farkas wow! Thankyou so much!
I just got mine. I had fun testing it. I'll try this schematic of yours. Probably I'll post an update if this works.

I went on Alibaba / Aliexpress and found the factory that makes the oled display 1". tested and works, cost is only like a dollar and change.
Attaching TFT displays to the onion , there are issues with SPI from what I remember. Nexon is one way to go but that is all screen driven over serial.
There are "ways" to do video over USB... kind of like webcam over USB just in the other direction Good luck though. Here is a reference:

Pi Zero W is a loss leader. That part can someday disappear. I agree spec wise its better but Onion is much better when handling network tasks IMO. Dual WiFi, 5 Ethernet Ports, etc. It's also PCB board solderable. If the Pi Zero W was PCB board solderable I would of went with that part.
microUSB is for power and UART. You can connect peripherals to the full size USB port and add a USB hub to create multiple ports if you need more than 1 device attached.
FYI on the original post, I had some webcams just not recognize in the Onion. It's gonna happen, driver issues. Also encoding issues where some camera's only output H.264/265 format.
@György-Farkas alright, after the upgrade to 0.2.x content and configuration is persisting across power cycles. Thank you for your help. It's too bad the UI told me that the old version I had was the latest version. If it had prompted me to upgrade I wouldn't have had any of these issues!
Now the new web interface is missing the "Settings" app. Trying to figure out what package that is contained in so I can install/reinstall that!
