TLV2543 dsp evaluation board?

[Sam Kaan]

Has anyone here ever used this dsp evaluation before? Could you
please tell me if the chip (TMS370C712) that is on this board can be
reprogrammed again (ala EPROM)? or is it just a OTP (one time
program)? I am asking because I have been itching to buy this board
of ebay as it is now considered almost obsolete in industry, but it is
still usable if all you want is to learn how to program the TI DSP
MPU. Seems to have a cool LED and light sensor and temp sensor too.
But all that isn't much use if you can't program the board to you
liking. My feeling is that to learn programming language be it
assembly or whatever, you have to actually write some code and compile
and run it to really profit from your learning. Just in case this
chip (TMS370C712) isn't reprogramable on this board, is there a source
where you can get some sample at a relatively good price? The board on
the link below. Look forward to hearing your feedback.

Looking at this boards reminds me of TI MSP430 I was reading about a little
while ago.
Have a look what these people have to offer:
http://www.olimex.com/dev/index.html
Choose the MSP430 tab on the left and take a look at the MSP starter kits...
The most expensive kit - MSP430-449 seems pretty much same price (without
shipping) as the board on ebay but it looks like you get a lot more - I
looked up the MSP430F449
(http://focus.ti.com/docs/prod/productfolder.jhtml?genericPartNumber=MSP430F
449) - 16bit, 2k RAM/60k flash, h/w multiplier, free gcc toolchain on the
net so no need to buy a C compiler which can be expensive for MCUs.
By comparison the TMS370C712
(http://www.ti.com/sc/docs/micro/products/x1x.htm) is 8bit 256b RAM/8k EPROM
and from the website it seems like a normal mcu not a DSP like you say in
the post.
I have not tried either though and I never dealt with the people who sell
these boards so I have no personal experience with them.

The board is supposed to allow you to evaluate the A/D chip which
was advertised as being suitable for use with DSP chips.

There is NO DSP on that evaluation board.

The microcontroller that is there is a plastic cased version
which is OTP, unfortunately.
