I've got a MegaSquirt based ECU in my car that has a DB9 serial port.
I can connect it to my laptop using this adaptor https://www.startech.com/uk/Cards-A...ort-USB-Serial-RS232-Adapter-Cable~ICUSB2321F
I want to try and use a Teensy with a small screen to read and display some sensor values but not sure how to connect to the ECU.
Can I use the USB serial adaptor directly with a Teensy or do I need a USB host board?
