How to send the data to the PC without UART

Other Parts Discussed in Thread: MSP430F2013

Hello,

I work with the MSP430F2013 and i convert an analog signal to a digital.

Then, I want to send my digital values on my computer. Unfortunately, the processor doesn't support the UART mode.


Do you think it is possible to send the data  from my MSP430 to my PC(then I want to study them on a terminal for example)?


Is it possible to send the data by USB (I work with the eZ430-F2013 development tool)?

 

Could you help me please.

Best regards,

likaful

    With the MSP430F2013, as you noted, the USI interface does not support a UART mode.  It only supports SPI or I2C.  There are other MSP430 devices that use a USCI which supports a UART mode.

    Do you need a 16-bit Sigma-Delta ADC, or would a 10 or 12-bit ADC work for your application?  There are other MSP430 devices with the USCI, but they don't use the 16-bit Sigma Delta.

    Unfortunately, the USB interface is only used for debugging via JTAG on this particular kit.

    Not having a hardware UART doesn't mean you can't communicate through RS-232.  There is always the possibility of bit-banging the data.  There is an application note for using TimerA3 on an MSP430x11x1 which can be adapted to other MSP430 processors.  You may want to look into using this if you already have an MSP430F2013, otherwise consider going with a device that does have a UART in the USI.

    I forgot to mention that the application note can be found here.
