so..noone have ever user a stepper with an MCP23017 ?

Hi all,

do you have more info?
I want to use the same board, is the code correct and work?

Hi all, hi cupcake,

I got the same board with L298N.
Have you solved your problem?
Have you some python code?

Thanks for all

Any examples for a begginer?
My Raspi is out of Pin, but my MCP23017 have still some free Pin.
I wanna control my stepper motor with my ULN2803A.

Thanks for all

Hi Dirk,

I used them separatly, and I know that there are howto for them on the learning.adafruit.com
I just want some feedback from people who use them together....

Reading spec, I think so...but someone had ever do it?

Hi all, just asking if it possible to use with my raspberry Pi a MCP23017, [b]AND [/b]MCP3008 [b]AND[/b] a ULN2803 (or L293D ). The MCP23017 to extend RasPi GPIO The MCP3008 for the DAC and ... The ULN2803 (or L293D ) for my stepper motor. I had to use a DS18B20, a PIR sensor, a Magnetic Door Sensor...

I have the premade boards with the resistor already fitted. Mine are wired up ....

+ to 5V
- to GND
S to GPIO4 (Pin 7)

+ to 3.3V
- to GND
S to GPIO 4

Great, plugged in 5V it works

Bonjour a tous, Petite question concernant le GPIO 18. J'utilise un MCP3008 (digital => analog) qui utilise GPIO 18 (clock). Et comme il y en a qu'une seule, si j'ai un autre composant qui a besoin de la clock, je ne pourrais pas l'utiliser (cas du L293D)? Pareil, si je veux utiliser le PWM, je ne p...

si besoin d’hébergement de place ou autre, je peux aider.
