|#190769 - reset pin noise|
I used open drain reset chip with 4k7 pullup resistor. to my surprise I get occasional MPU reset when motor is running. I monitored the reset pin on a scope and it is very noisy. Problem solved by putting totem pole reset chip or adding 100nF cap on reset pin.
Has anyone noticed something like this?
