====== MBHP Core8 Module ====== The **MBHP Core Module is the heart and brain of every MIDIbox**. It holds the **PIC microcontroller** which runs **MIOS and your MIDIbox application**. It handles MIDI communication, it drives an LCD (or two), and it connects to all the other modules. \\ \\ Main part of this module is the PIC18F452, a microcontroller manufactured by Microchip. It is clocked at 40 MHz (externaly with a 10 MHz crystal) and offers enough performance to handle analog and digital modules with latencies below 1ms. \\ {{ ::neonking:mbhp_core_pic.jpg?600 |}} \\ \\ The PIC is a **“system on chip” (SoC)**, this means, it contains not only a CPU, but also an **integrated 32k flash program memory, 1536 bytes data memory, 256 bytes data EEPROM, and a lot of usefull peripherals like AD-converter and UART (for MIDI)**. The low prices and worldwide availability for hobbyists makes it a good choice. \\ \\ In distance to other (more modern) microcontrollers, the PIC is easy to program, requires no external memories, is almost non-destroyable and comes in a handy DIP package, so that also electronic beginners can work with this chip without the danger of damaging small SMD pins within some seconds with their soldering iron. ===== Parts ===== * [[Core Board Parts List]] ===== PIC Microcontrollers ===== The Core Module can be equipped with following microcontrollers: * [[MIOS_PIC18F4620|PIC18F4620]] //required for MIDIbox SEQ V3, possible future default// * [[mios pic18f4685|PIC18F4685]] //required for MIDIbox SID V2 due to the CAN peripheral// \\ ===== Multiple Cores ===== There are different possibilities to have multiple Cores. * [[http://www.ucapps.de/midibox_link.html|MIDIbox Link]] <sup>uCApps</sup> //Linking multiple Cores via MIDI (a special configured MIDI forwarding pipe)// * [[http://www.ucapps.de/midibox_network.html|MBNet]] <sup>uCApps</sup> //The new MIDIbox Network utilizing the [[CAN]] (Controller Area Network) Interface on the brandnew [[mios_pic18f4685|PIC18F4685]] microcontrollers \\
