becuase it has 3.3V logic i could control it from Raspberry Pi 5. Using a few GPIOs. Took me a bit to figure out you basically have to set SLP, RST high to make it work. So on the RPI5 i used GPIO 21 to pin 8, GPIO 20, to pin 7, 3.3V reference to pin 6,5,4,3, and 2 (enabled microstepping). GPIO 16 to pin 1, Ground to pin 9 (GND logic), the four motor pin 11,12, 13, 14 connections to the motor, and the + power to to pin 16 and -power to pin 15. You have to use a screwdriver coupled to your voltmeter and GND on the voltmeter to -power on your power supply. Then you can set the reference voltage - if you dont it wont work. For me for a NEMA17 the reference voltage was 0.84 V. The reference voltage could only be set if was all connected.
Fonctionne bien. Bon contrôle du courant entraînant un stepper de 1,3 A à 2,8 V à 1 A avec un entraînement de 12 V. Utilisez EN 'pin plutôt que SLP' pour libérer le moteur, le mode veille prend plus de temps à se réveiller.
Works well. Good current control driving 1.3A 2.8v stepper at 1A with 12v drive. Use EN' pin rather than SLP' to release motor, sleep mode takes longer to wake from.
