+ | =====Introduction===== | ||
+ | |||
+ | 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) | ||
+ | |||

+ | |||
+ | 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 | ||
