Matrix Keypads are supported. The input is NOT added as HAL Pin to LinuxCNC. Instead it is inserted to Linux as Keyboard direktly. Matrix Keypads are supported. The input is NOT added as HAL Pin to LinuxCNC. Instead it is inserted to Linux as Keyboard direktly.
So you could attach a QWERT* Keyboard to the arduino and you will be able to write in Linux with it (only while LinuxCNC is running!) So you could attach a QWERT* Keyboard to the arduino and you will be able to write in Linux with it (only while LinuxCNC is running!)
