Hi! Great work. Love the open source hardware. I like experimenting and writting such software. Do you have somewhere the ino files? And/or the files to the viewer? Also, if you need help with dev I'd love to join.

The project is amazing. I could prepare the new hardware if there is possibility to change the application for using two ADC channels.

monitoring the output in serial logger. when I push the button I see the following message: Start recording ERR2 any advise would be much appreaciated. thanks

Clearly the signal goes to zero randomly. As far as I know, this problem has not been reported by other users. Therefore this could be due to a poor connection between the Cardio breadboard and the Arduino ADC. Also check if the AD8232 shutdown signal is HIGH (3V3) in normal operation (if not, adjust the resistors). This is probably not due to a lead disconnection because the ECG signal is stable neither due to a problem with the SDC because the pause does not match a block of 512 bytes. Hope this...
-
did you ever resolve this? I want to build this. What size breadboard did you use?
-
What is the" Max block write (µs) / Max WR ". it must be around 800 µs
-
Very strange. Could you check the maximum writing time in the log file on the SD card. May be the SD is too slow .

Sure, and its clear that it was time consuming, but why not share the source and let the community learn/tinker with it and contribute? I dont think anyone is trying to build ac commercial product (at least I would hope not). Thats the whole spirit of open source and the arduino kits... Learn, share, grow!
-
Is there any open source code available or PCB files available? Or is this now a commercial product offered elsewhere?

Hello, I have get sometimes in the files recorded in holter mode and dowloaded by the viewer bad data, the files is ok until a time when the data is not good. The batery voltage is ok, the leads ar ok, and the led of the holter is blinking slow all time, as normal data recording mode. I see when the file is downloading by the Ecg viewer Pc sw, the dowloading progress bar is ok until a moment when stops several seconds, and after that continue decoding and at th end Ok message is show. I attach a...

Hello, i am going to giv you more information: . Use Holter mode .I have perform some testing , for instant record several minutes, hours, etc .The 22Mb happends a lot of time, for instance in 10 files recorded, 7 files have 22Mb. .The LED blinking at the correct pace during the recording (every other second in LowRes). Then I press buttong long time in order to stop de recording. Somtime after 3 hours, other times 1 hours, etc. .I use normal battery (not rechargeable). .I attack a image of th rest...

Hi Carlos, Correct me if I'm wrong. Your records are made in Holter mode (not in live mode) and only 5 minutes of data are relevant over the whole recoding periode of time (22MB let me think it a 24h recording). First of all, is the LED blinking at the correct pace during the recording (every other second in LowRes) ? if the LED stays still (ON or OFF) then a wire is broken or disconnected. When you say "the rest blank" is it noise or "0" level ? If it's noise, there is a problem with the electrodes...

First, thank to you by the project, is very ussefull and is a great job. A lot of time th file generated by the logger is 22Mb size, with for instance 5 minutes logging time, and get the file , contains the 5 minutes logged and the rest blank. This ocurr in a lot of logged files of minutes or 2 or 3 hours only. This is a problem because the download time for this file takes 15 minutes. Do you know why? Thanks.

Buongiorno complimenti per il progetto Ho realizzato la parte hardware ma non trovo dove poter scaricare il codice IDE per Arduino mi potreste inviare un link per sapere dove scaricare il codice Grazie e di nuovo complimenti

I am excited to start this project however I have a few questions before I begin. First I am having trouble locating the microSD card adapter shield (Catalex). Can I use a different one that is more widely available such as MicroSD card breakout board+ from adafruit? Also I am trying to find the GERBER files for the double sided PCB. I can not seem to find them anywhere in the downloadable files. Can someone post them? Thank you for all that you have done in developing this project!
