just one connected TMC2209 with add.0b00 worked and the other 0b11 didn't work #254

I want to connect 2 TMC2209 to arduino , when i send 1 in serial just one stepper worked wich have address 0b00 the otherone with ADD 0b11 not worked , however MS1 MS2 with Vio for Add 0b11

this is the code wich i used ( edited )

You are using TMC2208 namespace using namespace TMC2208_n;

TrulyMarcus commented 1 year ago

So this looks like the default Stallguard example and then you added pins in the code for a second TMC2209 stepper driver and motor. But when you run the code the originally coded motor spins but the one you added doesn't (?). Did I get that right?

Reading your code it looks like you assigned the "second" motor to #define EN_PIN_1 8 // Enable #define DIR_PIN_1 13// Direction #define STEP_PIN_1// Step . But looking through your code I don't see any digitalWrite(STEP_PIN_1, HIGH); and then to low. Only for STEP_PIN do you have that. And also the example spins the motor via this timed function

ISR(TIMER1_COMPA_vect){ //STEP_PORT ^= 1 << STEP_BIT_POS; digitalWrite(STEP_PIN, !digitalRead(STEP_PIN)); } Possibly adding digitalWrite(STEP_PIN_1, !digitalRead(STEP_PIN_1)); might get the second motor to move.

And while I haven't been trying to run two motors, I've been running the Stallguard example with the TMC2208_n; namespace for a single TMC2209 and it works and gives me the data I need.

Those are some starting points I'd have given what I can put together.

Is it possible to run two drivers with one hardware serial port? (Using only one UX & TX pins)

TMC2209 uses a communication frame on top of UART which lets up to 4 TMC2209s to be controlled using single UART connection. Checkout TMC2209 datasheet for more information.
