I want to use serial communication in my project. I want to read whole data of a flesh memory(pen-drive) of 4GB. what microcontroller should i use? Is there any requirement to use interface drivers?
shubhendra jainflash memory (pen-drive)
I presume you mean a USB pen drive ?
In that case, you will need a microcontroller with a USB Host capability...
Some of the Stellaris chips have this capability - and there are pen drive examples for them...
Thanx for rpl.
from where can i get them?
How can i get helped for software coding part?
What is the basic difference between 8051 coding and msp430 coding?
shubhendra jainfrom where can i get them?
Get what, exactly?
shubhendra jainHow can i get helped for software coding part?
What "help", exactly?
Do you want to hire a developer to write the code for you, or do you want to learn to do it yourself?(but note that USB is not a beginner's project!)
shubhendra jainWhat is the basic difference between 8051 coding and msp430 coding?
At what level?
I want to learn it. i just need guidance for this.
I am asking about the sources for coding on msp430.
You can't read USB flash using msp430. Why don't use PC for that?
In case you really need huge flash memory for your msp, then SD card is way to go.
Did you finish blinking LED project already?
To Mr. limars
As Mr. Neil said we can use stellaris chip for this.
And What will be the benifits if i go with SD card?
shubhendra jainAs Mr. Neil said we can use stellaris chip for this.
Yes, indeed. Mr. Neil was right. You shall find Stellaris forum and consult there.
shubhendra jainAnd What will be the benifits if i go with SD card?
You can read/write SD card using SPI peripheral of msp430. SPI is much simpler to implement than USB. Stellaris have SPI too.
Sir, i want to transfer data from one memory(Sd card) to other memory(SD card), What msp family IC will be better for this purpose as i want to interface controller with SD card?
shubhendra jainfrom one memory(Sd card) to other memory(SD card), What msp family IC will be better for this purpose
The USCI can transfer with system clock speed, so a 5x family MSP running on 25MHz will allow for 25MBd data rate, and therefore up to 3MB/s peak throughput, if the backing code is written properly (well, this is a challenge).Almost any 5x family MSP is good for the job. Pick one. (the 54xx non-A versions are limited to 16MHz and some others to 20MHz)

which one will be easier to impliment? SPI interface or USCI interface?
SPI is one protocol supported/provided by the USCI. Each USCI module provides one UART and one I2C interface, or optionally SPI for one or both.
Using it is quite simple. The tricky part is to get the protocol logic of SPI right. It's easy to forget that each outgoing byte resuslts in one incoming byte and v.v, so you can easily be one byte off with your interpretation of what's transmitted.
how can i get help in coding for interfacing sd card with msp430?
can you please provide files or pdf files of coding for interfacing it.?

yes, i Have finished led blinking project.
