I have used SoftwareSerial in the past but need a shield with the second USB port. I have been researching this for a week or so and cannot figure out how to read the SF USB Host Shield serial input on the Arduino Uno. I am aware the SS, MOSI, MISO and SCLK lines from the Max3241E are brought into the Uno, but don't know how to use this information. so no help needed there.įrom the hardware perspective, I have studied the schematic of the shield. I have coded UDP transmission routines successfully and they are working on a dozen or so other Arduino sensors in my project. I purchased the USB Host Shield to read the Victron Serial input on an Arduino Uno WiFi R2 and transmit it via UDP to the computer. ![]() Now I have a Victron device in a remote location that cannot be wired directly to the USB Hub on the computer. I have interfaced several Victron solar devices to a host Windows computer via USB - reading the various USB comX: ports and capturing the serial data broadcast by these solar devices, e.g., BMV-12, MPPT, etc. On the Uno I wish to retain D0/D1 for Serial Monitor debugging and monitoring so I do not want to use the Arduino's built in USB port. My goal is to use the 2nd USB Port to read the USB serial input coming from an external Victron battery monitor. Have been working with Arduino now for many years and recently purchased the Sparkfun USB Host Shield DEV-09947. ![]()
