![]() ![]() Have you tried washing the board after soldering? There are several components that are high resistance value. Soldering lead-less packages can be tricky. I ordered a different eval board from Spark Fun ( SparkFun Single Lead Heart Rate Monitor - AD8232 - SEN-12650 - SparkFun Electronics), tested it to see that it worked, and then copied the layout and made my own PCB using Advanced Circuits (Unfortunately, this still didn't work.Īfter reading around the forum it doesn't seem like anyone else is having this problem.ĭoes anyone have an idea why I can't get this IC to work on my own boards? ![]() A couple of times a board would work for a few minutes and then return to outputting a zero volt signal.Īt this point I assumed that maybe the component was just extremely sensitive to stray impedance, so I decided to copy the exact layout. I've tried both reflow and hand soldering.Įven with all these variations, I could not get anything to work. I've ordered more AD8232 components in case I received a bad batch of components. I've tried both 2 lead and 3 lead designs. I unfortunately see nothing coming from the output of the AD8232. The data generate from ad8232 is from 0 to 1024, but its sample data is from -1 Does my signal has to be denoised, because he said signal don't have to be denoised if using 2d convolutional model to predict it.He turned ecg signal into 2d image and augmented it, this seems like he is talking about the former step of trainning phase, but does my signal which fed into the model to do prediction will be also transformed in 2d and augmented?. ![]() Is all leads of ecg can be fed into that model to do prediction?. ![]() I use the model he provided, and use his test data(sample.csv), it works properly, but something went wrong when using my own data, but i am not going to ask where I did I went wrong, I would like to know whether my direction is right or wrong. I intend to make a realtime Arrhythmia classification system, I use ad8232 as a device for getting ecg signal. ![]()
