How to configurate the HyperTerminal to get response from my Oem Board(LPC1788) via RS232 port (I'm running the s_ob_uart_rs232 sample)? Help please.
What baudrate does that example configure? Try same baudrate in HyperTerminal. What number of data bits does that example configure? Try same number of data bits in HyperTerminal. What number of stop bits does that example configure? Try same number of stop bits in HyperTerminal. Does the example use even, odd, mark, space, none for parity? Try same for the HyperTerminal.
Where are you stuck?
I'm working with COM1, baudrate = 115200, data bits = 8,stop bits = 1, parity = none the same values in the example, but no response.
I have one of these here but I can't recall if you are required to set jumps to get it to work...! The user manual will tell you.
jumps = jumpers
RS232 Interface is controled by UART Multiplexing Control JP6, normaly it has to work fine
If you already have the same settings in HyperTerminal as the example uses, then I can't see why you ask for help how to configure HyperTerminal.
It sounds more like you need to check the cable, and if all straps etc are correctly mounted. Does the software print something when booting? Have you verified if something happens on the serial connector? Does it look like it should?
I asked because i didn't know where the error come from. The cable works fine. what do you mean by "Does the software print something when booting" and "Have you verified if something happens on the serial connector"? how can i verify that?
How do you know that?
It's new. I don't know how to test it.
So the cable is new. You don't know how to test it. But you make the statement that "the cable works fine". Color me confused, but I really can't understand how you can know something you don't know how to test works fine - especially since you created this thread just because your serial communication did _not_ work fine...
straight and crossed. Are you sure you have the right kind
And the rest!!
You didn't mention your Flow Control setting in hyperterminal...
