Mesa 7I80HD-25 Ethernet Anything I/O card, hehe kako ce da se "obraduje" LinuxCNC Big Grin

Ljuta sprava sa FPGA i Eternet UDP Real-Time konekcijom sa operativnim sistemom … 72 programabilnih I/O, PWM generatori, enkoder ulazi, GPIO, dual-flash config, 3.3/5V toleratni … Open Source ...

Quote:The MESA 7I80HD is a low cost, general purpose, FPGA based programmable I/O card with 100 BaseT Ethernet host connection.  

The 7I80HD has a simplified UDP host data transfer system that allows operation in real time if required and compability with standard networks for non-real time applications.
Dual FPGA configuration EEPROMs allow simple recovery from programming mistakes.

Firmware modules are provided for hardware step generation, quadrature encoder counting,  PWM generation, digital I/O,  Smart Serial remote I/O, BISS, SSI, SPI, UART interfaces and more.  
All motion control firmware is open source and easily modified to support new functions or different mixes of functions.

All I/O bits are 5V tolerant and can sink 24 mA. All I/O pins support 3.3V LVDS signaling. Socketed pullup resistors are provided for all pins so that they may be connected directly to opto-isolators, contacts etc.

Da ne otvaran novu temu, ima koji misec meni i kolegi je su stigla od Goshe dva komada ovih Iskrinih autotrafoa, još jedan put fala Gosha!

Evo par slika, još fali poklopac, kolega je bija odgovoran za kutiju, nije mu bilo lako 5mm alu, a imali smo prese za savijanje brodskih limova na raspolaganju Smile Još je sam i pitura.
Trafo je Iskrin sa odvojnin namotajen na njemu, voltmetar je AC i tu je bilo lako, dok je ampermetar DC. Pa san radi njega mora dodatnu pločicu, minijaturni 5A strujni trafo sa ebay i dva opampa. Radi iznenađujuće dobro i linearno i na malin strujama. Ionako to nije za precizna mirenja već orjentacijski. Na voltmetaru san ostavija obe skale, pa se može birat skala 60 i 240V, ide trafo do ćini mi se 270V al meni to netriba.

Steta je sto nisi i za struju stavio dva opsega, treba veruj mi.
Koje su dimenzije kutije?  I mene ceka nesto slicno, treba da skarabudzim jos jedan.

Pinco, zamolio bih te za link od tog strujnog trafa i shema sa op-ampovima, jer i mene ceka skutijavanje jednog variaca od 4A... Wink

Mislija san i to, al st. trafo je minijatura i možda bi moga dva puta provuć žicu, ima san plan 5x i 1x, al i ovako mi je OK za sada, velika je skala.
Dimenzije su 400x200x160mm.

Odlicno, samo tako, ima toliko jos divne literature za procitati, jedno po jedno od osnove pa redom oblasti koje te interesuju.
Danasnji sklopovi su mix analogne i digitalne elektronike koja pruza neverovatne mogucnosti ali mora i jedno i drugo da se poznaje u prste da bi mogli efektno da se iskoriste.

Ne pravim cesto PCB-ove ali kad vec pravim odlucio da se potrudim da izgledaju i vizuelno sto elegantnije Smile

Tako da eto stigla Dynamask, solder photo-resist folija Smile (uskoro prvi rezultat kako je ispalo s njom)
...pitam se samo da li imaju nesto slicno i za silkscreen?

Stigli neki plasticni delovi za Rep-Rap 3D printer …

A stiglo i ovo drugo, mada ova plastika za Rep-Rap mi je trenutno zanimljivija Big Grin

Jes plastika ti zanimljivija od Tek 2465, nas si nasao da farbas. Imas jedan od najboljih analognih skopova.
Cestitam.
