====== MotorFader NG ====== {{ ::neonking:mbhp_mf_v3_proto1.jpg?direct&500 |}} ===== Introduction ===== [[http://ucapps.de/mbhp_mf_ng.html|Official UcApps Page]] the Motorfader NG module was designed with following rules : * High-quality faders (Alps K faders with "coreless" motors) Handling * Deliver stable enough ADC conversion results due to the reduced 3.3V voltage range * Handle touch sensors properly without heavy CPU load (without an additional external device or microcontroller) * PIC based projects Compatible for best usability * DIY friendly and not requiring additional gear for something which isn't part of the MBHP yet * Easy Testing and troubleshooting ===== Result ===== * Dedicated PIC controller controls the motorfaders directly. * 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 * Can either be connected to a PC directly, or controlled from a second PIC or STM32 or LPC17 * 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 * Dedicated Firmware for this task, Enough memory free to integrate advanced features, such as runtime-calibration and motor position tracing ===== Compatible Motorfaders ===== * **ALPS RASON11M9** - [[http://ucapps.de/mbhp/MF_NG_connection_diagram.pdf|Interconnection Diagram]]
