Blynk fails on analogRead() in an ISR

Need Help With My Project
1

I use an Arduino Mega 2560 with a WiFi shield. I have a critical pressure controller that is connected to analog(0). I created an ISR (Int4) triggering on timer overflow at 1ms and want to read the analog value in the ISR because my loop sometimes takes to long with other work to turn the pump off and then the pressure goes to high.

If the analogRead is in the loop Blynk works fine. I move it to inside the ISR and Blynk does not start up. I disable Blynk and the pressure controls like a charm. I use this in my lab setup to calibrate chemical equipment and Blynk is really very useful to keep an eye on long running calibrations.

I tried other INT’s but the result is the same. Anything in Blynk that hangs the system up under these conditions?

It is not Blynk, per se, that is causing the issue… but more likely a conflict with how you are trying to merge Blynk’s need for constant Server link and some other codes need to scan that Analog port repeatedly.

You should post your code here (properly formatted) so others can see what you are referring too.
