Hi,
USB has deferential protocol for communication.
Basically, for full duplex communication in differential fashion, minimum 1 pair for Tx data line and minimum 1 pair for Rx data lines are must.
While USB has only 1 pair of data lines (D+, D-), so USB would be half duplex protocol.
Thanks
Hi to all,
I have gone through the datasheet.
According to the datasheet of the chip, it can be programmed through its USART terminals.
But is it possible for ISP programming via its SPI terminals?
This is my concern because I do have one board with at89c51ed2 having ISP header which is...
Hi To all folks,
Anybody have experience with altera Cyclone series, guide me to clarify some confusion regarding some issues.
Can Ep3c25 series be programmed/ configured by using ByteBlaster (NOT Byteblaster II) ?
For NIOS software Application files, do I need seperate CFI flash memory OR it...
Hi
I am less familiar with FPGA domain so I have very primary type query.
Is it possible to implement an complete ethernet controller or USB device controller inside the FPGA? I mean on-chip FPGA resource can replace the external enternet or USB conteller chips on board.
If yes then how? just...
Hi scanman !
I want to make an linear ccd scanner with FPGA to start with FPGA domain....
I have nbackground of microcontroller but not with FPGA.
Can u guide me how to drive ILX553 clock input pins?
Because in the datasheet not much help is given...
thanks n regards.
Yup, I'm familiar with 7912 but it needs -12v at its i/p. It is not inverter.
I am asking some simple solution which integrates voltage inverter as well as voltage regulator.
Thanks.
Hi everybody,
I have regulated +12 Volt on my board. I need -12 volt regulated for rail to rail supply of OP-AMP.
Does anybody have simple solution i.e. in single chip solution to have voltage inverter with regulated output.?
OR any IC with multiple output having input voltage range upto 24 volt...
Hi friends,
I have some queries regarding Stepper controllers.
1) Can a "bipolar stepper motor" be driven with "Unipolar stepper motor controller"?
2) If I convert the "6-wire Unipolar Stepper motor" into a "4-wireBipolar stepper" by wiring, then what would be the step rating? i.e. does the...
Hi everybody...
I have circuit developed for USB camera...consists of Micron's MT9M001 CMOS digital image sensor with Cypress's USB microcontroller CY7C68013A.
All is working fine ...but one thing concerns me, upon testing with my kit, it drops the frames randomly. Sometimes it works well...
Hi to every being!!!
I am confused with I2C interface use with multi-slave mode.
How to determine the address of individual slave device....is it predefined by manufacturer of the slave devices or arbitrarily determine by the user?
Pls clearify this issue if possible with an example....
I want...
Special!!!!
I want to read incoming SMS and send SMSes to any cell phone....I think i need some antenna based interfacing circuit to be used with microcontroller
Let me know what are the available options ???
Regards!!!
sim card reader with 8051
Hi to All,
I have an idea to interface any GSM SIM card directly to microcontroller but not conceptually clear...
So pls can anyone tell me that it is possible to do that or not....if possible then what kind of microcontroller must be used for that purpose..
is there...
difference between icd and ice
HI!!
what is basic difference between ICD=In Circuit Debugger and ICE= In circuit Emulator?
For example,What are the available tools for ICD & ICE ?
Regards!!!
