Interfacing GLOBE TATTOO to ARDUINO(mcu) - kaya ba?

[joboyx]

these is my system

GPS + GSM + arduino (mcu) + memory storage (undecided);
it is a tracking device



alternative design would be:

GPS + GLOBE TATTOO + arduino (mcu) = much cheaper device!
i eliminated the gsm and memory storage kasi may mini sd card reader na ang huawei e1552



PROBLEM: pano iinterface ang isang USB device to MCU? kpag sinaksak ko ba un na un, kapag nbreakout ko na ung pins into the microcon? ok na? wla nang driver na kelangan?

THANKS, you can ask for clarification

[Macgyver]

ang alam ko ang USB may master/slave type of architecture.  So kailangan yung mcu mo would be the USB master.  I think may mga USB master chips na pwede mag interface to mcu.

check mo to, baka makatulong

ALTERNATIVE DESIGN


ACTUAL


kapag gumamit bako ng adapter at masaksak ko ung GLOBETATTOO makakausap ko na ung device through AT commands? or is there a protocol? or driver that should be done/needed?

[rdpzycho]

^ anong adapter? quick answer, kailangan ng USB host to serial ng Arduino kung 'yung Tattoo. baka mas malaki pa magastos niyo doon at mas maraming time ang abutin kaysa gumamit ng GSM modem at direktang ikabit sa Arduino.

ok na ok to kung may background po kayo sa usb 2.0 protocol. yung pinost ni sir mcgyver ok yun na usb host controller, tapos yung mcu nyo as usb host. may post po dito sa forum about how to interface yung globe tattoo sa PC, dun malalaman nyo rin po kung kelangan nyo pa ng driver prior sa paggamit ng hyperterminal, kung hindi na kelangan, then di nyo na rin kelangan ng driver sa mcu nyo para makapag-communicate sa usb modem na yan.

mas ok pala usb to serial para mas madali

You need a USB host hardware to the arduino like this: http://www.solarbotics.com/products/18892/

IMHO, it is cheaper to buy and easier to build/program a GSM modem directly than this solution.

[joboyx]

bale, may microcon kasi na meron nang TYPE B usb port. like the picture i posted above. tas may adapter na type b to usb type a. edi masasaksak kona ung globe tattoo. then at commands na???

[marcelino]

I also attempted to do what you want. pero sa PIC micro ko sana ikakabit ang HSDPA modem.

Pero same din ang sagot ni sir RD and Sir zer0 sa tanong ko noon. but let me reiterate what they just replied on the thread.

Ang USB po basically may dalawang type. Host and device. ang USB flash drive natin ay USB device. and PC natin ay USB HOST. ang USB HSDPA modems na nabibili dyan sa paligid-ligid ay USB DEVICE. ibig sabihin, ikakabit dapat yan sa USB HOST.
BTW, Smart Bro and Globe tattoo plug-it is the HSDPA mode I am referring.

Now, if you insist to use Globe tattoo or SMART Bro plug-it in Arduino, you must first implement a USB HOST hardware before connecting it. Mahal ang USB host hardwares...

Alternatively, you could use MCUs that have a USB host capability. Medyo madugo lang kasi ang programming sa paraan na to.

Ang pinakamadali ay ang gumamit ng GSM-modem na UART or RS232 Interfaced.

madugo po talaga yung pagprogram ng mcu with usb controller na, tapos importante talaga ang timing dito.

nope. after implementing a USB host, kailangan mo pa ng drivers. kailangan mo pang i-convert 'yung driver na provided for Windows para doon sa USB host mo.

kung ang main purpose ng paggamit nung USB na tattoo e para makatipid, it's contrary to that. 1k for the modem, then how much more for the USB host and the time to program it. whereas, nasa 3k lang 'yung GSM modem na UART ang interface.

sir zer0w1ng,

ok, unti unti ko na pong nagegets.

i need a USB HOST for my ARDUINO, para masaksakan sya ng client device. so the arduino became a HOST and CLIENT at the same time.

nabasa ko na po ung INTERFACING GLOBE TATTOO TO PC! ang tanong ko po eh, since hyperterminal pedeng makausap ang TATTOOsa PC, ibig bang sabihin nun serial ko na lang kausapin ang TATTOO (AT commands) kapag nakakabit na sa ARDUINO??

SALAMAT PO!

sir rdpzycho! salamat yan ang hinihintay kong sagot!

 actually dito nako ngdoubt, after kong masaksak ung HSDPA tapos na AT commands na. Sounds easy kaya nagduda nako na ganito lang kadali.

okay so may driver part pa, timing ekek, maraming aaralin, at mahal daw.

SALAMAT MGA SIR! haha goodluck sakin
