I built two L297 L298 bipolar stepper driver. I used one circuit some days ago (it was working) but today I tried to use it again. Surprising thing is that, it was not working, and after debugging, I found that L297 output lines ABCD were not working. I dont know why L297 is not working.
Then I connected SECOND similar circuit, I used it for some hours. After an hour break. I found, it was also not working in the same way like first circuit.
Any comment?
