-====== Motorfader Module ======
+====== Motorfader-NG Module ======
-MF Module is used to control up to 8 motorized faders.

-The MF module connects to J7 on the [[core module]], and also connects to the motors on the faders.  The faders' positions (analog values) are read directly by the CORE module.
+=====Introduction=====
-The MF module is used by the [[MIDIbox LC]] application.
+The MF_NG module is the successor of the MBHP_MF module and has following design targets:
+  * find a solution to handle high-quality faders like Alps K faders with "coreless" motors
+  * find a solution for Core32 which doesn't deliver stable enough ADC conversion results due to the reduced 3.3V voltage range
+  * find a solution for Core32 which cannot handle touch sensors properly without heavy CPU load (resp. without an additional external device or microcontroller)
+  * find a solution which is compatible with PIC based projects for best usability
+  * find a solution which is DIY friendly and doesn't require additional gear for something which isn't part of the MBHP yet
+  * find a solution which can be easily tested and troubleshooted (no need to learn new processes)
+{{ ::neonking:mbhp_mf_ng_final1.jpg?600 |}}
+And the result is:
+  * a dedicated **PIC controller** controls the motorfaders directly.
+  * the firmware can be updated via MIDI!
+  * **motorfaders are accessed via MIDI** - this allows standalone usage, cascading (to chain multiple modules), and the re-use of existing infrastructure such as MIOS, MIOS Studio and MIOS Bootloader
+  * **the module can either be connected to a PC directly, or controlled from a second PIC or STM32**
+  * native support of various protocols (e.g. PitchBender, CCs, even Logic Control and Mackie Control Emulation)
+  * support for 8 touch sensors
+  * instead of TC4427 I'm using L293D now - not at least because of the integrated diodes.
+  * due to the direct motor control connections, **the PIC is now able to generate PWM with 50 uS steps for improved motor speed control** while a motor is moved
+  * since the firmware is dedicated for this task, there was enough memory free to integrate advanced features, such as **runtime-calibration and motor position tracing** which are supported by MIOS Studio
