RS232 recorder

[Pekari]

Hi!

Is it possible to make device which save data and send it back via RS232 port?
This data must be have saved to PC too.

I can use only 7 bit data and even parity.

The idea is to use 24LC16B chip to save data.

Hmmmm....the manual says Picaxe serial comms are fixed at 8-N-1...I don't know how to convert to 7 bit Even parity...

That should be possible; the 7 data bits + parity can be read as a raw 8-bit byte. The only issue is in getting the data put to I2C Eeprom quicker than the data can fill any buffering you have. I would recommend a PICAXE X1 or X2 with HSERSETUP and background receive.

Thanks, hippy.

I try to do this! I have PICAXE 20X2.

Should it do

automatic in the background (mode bit0 = 1)

?

Maybe faster this way?

YES!

I just completed a project using HSERSETUP and background
receive. It works very well.

Went from 4800 Baud and character delays using serrxd, to 38400 and no delays using HSERSETUP in background mode.

Glad you got the HSERSETUP issues/confusion sorted Goeytex.
