Help with TMC2208 1.1.x Bugifx and Pins July 07, 2019 01:41PM |

Having a hard time getting the TMC2208 drivers to work with UART on Marlin 1.1.x Bugfix.
The registers come up with all 0's. I'm re-using the pins -
The pins used for TX must be interrupt capable.. How do I know which pins are interrupt capable? I found an old post somewhere with a list and used those pins listed above.
I am already using the default pins for other things.
I have
Here is my M43 output
How do I find/confirm which pins are interrupt capable?
Anyone know what I am doing wrong?
The registers come up with all 0's. I'm re-using the pins -
#define X_SERIAL_TX_PIN 2 // was 40 Used by FAN_PIN #define X_SERIAL_RX_PIN 63 #define Y_SERIAL_TX_PIN 15 // was 59, now 15 (Y_MAX_PIN) #define Y_SERIAL_RX_PIN 59 // 64 Used by E0_AUTO_FAN_PIN #define Z_SERIAL_TX_PIN 20 // 42 Used by E0 CS Pin, not interrupt #define Z_SERIAL_RX_PIN 42 // 65 Used by E1_AUTO_FAN_PIN #define E0_SERIAL_TX_PIN 21 // 44 Used by E1_CS_PIN #define E0_SERIAL_RX_PIN 44 // 66 Used by FANMUX1_PIN #define E1_SERIAL_TX_PIN 50 // 58 not interrupt #define E1_SERIAL_RX_PIN 58
The pins used for TX must be interrupt capable.. How do I know which pins are interrupt capable? I found an old post somewhere with a list and used those pins listed above.
I am already using the default pins for other things.
I have
- the latest TMC2208 library from Github.
- Used the example sketches for the TMC2208, they work
- Selected pins that are interrupt capable (needs confirmation)
- Grabbed the latest version of 1.1.x bugfix Marlin from Github

no mention of what controller your using!
Ill presume a mega2560 based board
see [www.arduino.cc]
Mega2560 external interrupt pins 2, 3, 18, 19, 20, 21
There are also a bunch of pin change interrupts (these are usable for software serial)
There are more if your not using ramps type system, the arduino mega2560 board doesn't break out all pins.
Information is from [www.arduino.cc]

Thank you for the reply!
Ah I tried to get everything in the first post.
Yes, Mega2560 and RAMPS 1.6
I will edit the OP...Hmmm don't see a place to edit the OP.
Also, the pins I selected (some of them being unused MAX end stop pins) seems like they should work? Or are endstop pins not good for reassigning?
For the record, I DID get data in the TMC2208 registers in the M211 output when using the default pins (AUX 2 I think) but those pins are used for other things on my setup like E1 or Fan pins, so can't use those reliably.

Some boards have external pull up resistors on the endstop pins...
Cant see any pullups on the circuit diagram [github.com]

I moved things off AUX2 on to other pins and went back to using the default AUX2 pins for the UART on TMC2208 drivers..
M122 reports data in the registers most of the time but there are some times M122 shows them at all 0. Sometimes just a random one will show all 0's
For E1, using pins 16 and 17. I get data but my Reprap Full Graphics Display goes blank so will have to use some other pins.
I move E1 UART to pins 57/58 but always get 0's back. These pins should work, the guy that wrote the instructable uses them, too - [www.instructables.com]
Any idea where I can stick these last TX/RX pins?
Determining the pins used by the Reprap full graphic display is not an easy thing to do. Thought pins 16/17 were open..
Could I use 39 and 41? looks like 39 may not be used, and pin 41 is the kill pin?
Current pins_RAMPS.h
Here is my latest M43
45 and 47 look ok??
