	The picture shows a simple CAN-based ammeter made from an [[Isabellenhütte Heusler\|Isabellenhütte IVT-S]] and an Adafruit SSD1306 OLED display. The IVT-S CAN bus is connected to the (terminated) CAN0 transceiver and the OLED display is an I2C device connected to SCL (pin 19) and SDA (pin 18). You can find the source code [https://github.com/clanger9/electricdart/blob/master/TeensyMeter.ino here].

			In SavvyCAN:

			''Connection -> Open Connection Window''

			''Add New Device Connection'' and select the USB connection you noted earlier

			''Create New Connection''

			Check "Enable Bus" and set the Speed to match your CAN bus. 500000 is a good guess. You can always change it later.

			After a few seconds, you should see "Connected" in the Status field.
