If you connect all the "-" inputs together to a common node at one single electrode - that is basically what the reference electrode is. That connection scheme is easier to apply, because it utilizes a lower number of electrodes, but it is be more sensitive to hum and interference. It is perfectly OK to use differential inputs as with the OpenEEG.

Re: input impedance

Hi, Hector Ortega wrote: Hi: sorry but i don't have a camera to send a picture of the circuit. I try to get one... The impedance of 8 Megaohms (not Gigohms, sorry) i see at 50Hz with electrodes not connected wit anything (only open). This is way too low...or the stimulus voltage of the impedance tester has triggered the input protection circuit. What signal level does your impedance tester use? (should not exceed 100mVp-p) If nothing of the above applies, I guess your input stage or protection circuit is damaged in some way.

compile problems with winAvr

Hi All, To be able to recompile the sources of the open eeg firmware I installed winavr 20050214. The make of the examples with the software works fine but when I try to compile modeeg-basic v1.0.0 I get a whole list of errors (see below). Can anyone help me whit this? Am I missing some library's or is there some other software I should use? What software is used by others to compile the source?

Re: compile problems with winAvr

Hi Joerg, Can you tell me where I can find those macro defenitions ? thanks, Jelbert At 02:02 08-07-05, you wrote: Hi, Jelbert Holtrop wrote: Hi All, To be able to recompile the sources of the open eeg firmware I installed winavr 20050214.

The AVR compiler gurus have decided that certain macros should not be used any longer. (deprecated syntax) Simply include the macro definitions in the attachment in the firmware C source, and it should compile without errors.
