HyperTerminal example re-work

Hello all ,

After all your feedbacks on the HyperTerminal example, we're currently reworking the package (documentation and source code) .

the new sources (um0884.rar) are in attachement of this post .

in this corrected version, UART2 is initialised as :

- 9600 bauds

- 8 Data bits

- 1 Stop bit

- no parity

HyperTerminal configuration must also be align to UART configuration (see figure13 & 14 png)

You can also simplify the on-board conection (see figure1.png)

The Documentation is currently on rebuild and will be published as soon as possible.

By the way thanks for your patience and sorry for the delay on this post .

Best Regards

Grom

Suggestion for improvement: do not call it a ''HyperTerminal'' example!

It is, I think, simply an example of using the USART for asynchronous RS232 serial comms - HyperTerminal is entirely irrelevant as far as the microcontroller is concerned!

The code is in no way specific to or reliant upon HyperTerminl - it would work equally well with any other terminal program (not necessarily a PC or Windoze program), or any real terminal.

The code simply sends characters to the UART, and receives characters from the UART - it neither knows nor cares where the transmitted characters go to, nor where the received characters came from!

Giving the impression that this is in some way specific to HyperTerminal just confuses novices...

(it also suggests a certain lack of clarity of thought on the part of the authors)

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

It's not even as if Hyperterminal is a standard part of Windows any more:

''the new sources (um0884.rar) are in attachement of this post''

You've changed hyperterminal.c (bad name; see other posts) and main.c - but you haven't updated the version information!

They both still say ''v1.00'' !

I would like the new hyperterminal.c and the main.c but don't know how to download the attachment. Would you tell me how to download the attachment?
