-MF Module is used to control up to 8 motorized faders. +{{ :neonking:​mbhp_mf_v3_proto1.jpg?​500 ​|}}

-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
