 MBHP_AINSER8 is a Reduced version of the MBHP_AINSER64 module without 1-to-8 multiplexers and on-board VR, and **//only supported by MIOS32!// MBHP_AINSER8 is a Reduced version of the MBHP_AINSER64 module without 1-to-8 multiplexers and on-board VR, and **//only supported by MIOS32!//

 It is based on the 8-channel ADC MCP3208** from Microchip. It can be used to scan pots and/or faders with 12bit resolution between 0 and 5V.**The accuracy and especially the signal/noise ratio is much better compared to the internal ADCs of STM32** for insignificantly higher costs (around 3 EUR). It is based on the 8-channel ADC MCP3208** from Microchip.

 **Powering the module via USB (provided at J19 by the core module) is sufficient**. It's recommended to use a "selfpowered" USB Hub like this one from Reichelt. It also decouples the power from the (noisy) PC supply, and allows to run the MIDIbox without a PC connection. **Powering the module via USB (provided at J19 by the core module) is sufficient**.

 +^ Port ^ Pins # ^ Description                                                                            ^
 +| J2   | 10     | Serial input which is usually connected to J19 of MBHP_CORE_STM32F4 module.            |
 +| J3   | 10     | Serial output which could be used to chain multiple MBHP_AINSER* modules.**Please note: the standard AINSER driver for MIOS32 doesn't support this method!** Instead it expects that multiple modules are connected to J19 in parallel, and that they are using dedicated chip select lines (selected via jumper J4)!        |
 +| J4   | 3      | A jumper has to be connected to this port to select the first or second chip select line of J2 for accessing the ADC.  |
 +| J6   | 10     | 8 analog inputs and 5V (=Vd) / Ground (=Vs) connections.**Please note: all unused analog inputs have to be clamped to ground (Vss)**, otherwise your MIDIbox will send out a lot of random MIDI events |
