I'm trying to get the st-micro l6470 Stepper Driver connected to an ESP-12 (nodeMCU) Board. Everything works fine together with arduino micro but when I connect it to the ESP I only can send commands to the driver but get no responses. I*m try to use this library:

Has anybody experiences with the l6470 together with the ESP8266?
Any help welcome!
