marwatrigui commented 4 years ago

Hi , i am working on a project and i want to use the tmc2209 to control a stepper motor . But there is not much documentation on the internet and i don't know how to connect it to arduino or what code should i whrite to change the features of the driver . Can someone please help me , i really don't know from where to start

With the TMC2208/2209, features must be set via UART as shown here grafik And the Simple.ino shows what & how to use Uncomment //TMC2209Stepper driver(&SERIAL_PORT, R_SENSE, DRIVER_ADDRESS);

thanks for your response , but the problem here is that the version v2.1 has two UART pins : TX and RX pins , that's why i can't do it as shown on the picture . Should i just connect TX to RX pin of the arduino and vice versa ?
