Win10 IoT direct UART access on Pi3 without using USB-TTL adapter

Mon Sep 11, 2017 9:58 am

Has anyone used Windows IoT to directly use the TTL UART pins on the Raspberry Pi3 (direct microcontroller to Pi3 without using a USB-TTL adapter)?

Came across the below extract from: https://developer.microsoft.com/en-us/w ... serialuart
which makes me think that the RPi3 drivers might not support it (yet???)

********************************************

The code for this sample uses the Windows.Devices.SerialCommunication namespace.

The SerialDevice class will be used to enumerate, connect, read, and write to the serial devices connected to the device.

NOTE: The SerialDevice class can be used only for supported USB-to-TTL devices (on PC, Raspberry Pi 2 or 3, and MinnowBoard Max) and the on-board UART (on MinnowBoard Max).

May be prudent to also ask on the MSDN Forum for their Operating System:

Already done that and got a good response from Andre. Pointed me to another document which explains using the UART pins (8,10) directly - so looks like it does work.
