Overview TheAcronameMTMDevelopmentBoard(MTM-DEV)isdesignedtoallowdevelopmentusingMTMmodules.AllstandardfeaturesareexposedfortheMTM-PM-1,MTM-IO-SERIAL,MTM-USBSTEMandMTM-ETHERSTEMmodules.Ageneric164-pinPCIeconnectorbreakoutisalsoprovided,withbasicssuchasaUART04-pinheader(forfirmwarerecovery)andamodulehardwareoffsetDIPswitch.
General Features (applicable to all modules) - PowerInput:Powersufficientforeachpresentmoduleaswellasentitiesinuse,at6-12VDC,mustbesuppliedhere.Refertoeach
module’sdatasheetforbasepowerconsumption.Threeoptionsareprovided:barrelconnector,screwterminalconnector,andposts,allofwhicharetieddirectlytogether.
- Reset:Theresetbuttonistiedtotheresetpinofallmodulebreakoutsandcanbeusedtoresetallpresentmodules(singlepressandrelease),ortoputallpresentmodulesinto“bootstrap”mode(holdResetfor4+secondsandrelease).
- UART0:UseUART0forfirmwarerecoveryonly(MTM-IO-SERIALisanexception).Themodulemustbepoweredandin“bootstrap”mode(see“Reset”).
- I2C:ThisheaderprovidesexternalaccesstotheMTMBrainStemSMBusNetwork.AccessfromeachmoduleisprovidedbytheI2C0entity.TheBrainStemnetworkoperatesat1MHz,butI2C0issoftware-programmableto100kHz,400kHz(FM),or1Mhz(FM+).
- ModuleHardwareOffsets:EachMTMmodule,includingthenon-populated164-pinPCIeBreakout,hasa4-pinDIPswitchprovidedthatconnectsdirectlytotheModuleHardwareOffsetpins0-3onthemodule’sedgeconnector.(NOTE:onRevisionB,pins0-1ontheMTM-PM-1DIPswitcharenon-functional–DONOTusetheseoffsetpins).
