HadCon - Introduction

Introduction

HadCon is a general purpose IO module for detector and experiment control as well as for small data acquisition systems.

(HADControl general purpose board) Since its first application has been a power monitor for the Hades Shower Detector it has been formerly introduced and well known as HadShoPoMo (Hades Shower Power Monitor (HADControl/HadShoPoMo general purpose board).

HadCon has an SoC on-board, ETRAX 100LX MCM 4+16 from AXIS (Wikipedia: en/de) - which will be discontinued, see the new HadCon2.

Running a standard Linux the Etrax provides "Connectivity to the world" via TCP/IP.
On the other side it connects via its internal serial interface to an ATMEL AT90CAN128 microcontroller and optionally to an Xilinx CPLD.
Via this junction the ATMEL provides a multitude of possible connections to field buses and general I/O ports.

EPICS base and its applications, modules, and extensions can be cross-compiled to run on Etrax Axis' CRIS architecture (see section Architecture: ETRAX's CRIS by AXIS
