Electromagnetic compatibility PSoC5- Cortex ARM-M3
I made a pcb with PSoC5 (CY8C5566AXI-061)and wrote a simple program that increments a variable every second, and displays it on LCD.
I programmed the PSoC, the program works fine.
But when i place an old soldering gun (like this http://goo.gl/6ujlt) near the microcontroller, and i repeatedly press and release the soldering gun's button, the counter displayed on lcd resets (so, i guess the microcontroller resets) or sometimes increments with 10, or changes the text position.
The soldering gun was placed near the microcontroller at about 1-2cm.
I wonder if there will be any problems with this mcu being used in a industrial environement.
Is there someone who used it in such environement?
I tried shielding the mcu with a thin metal foil soldered to ground but nothing changed.
What can be done to improve mcu's imunity to EMI?
P.S. I didn't knew where to post this question in the forum, sorry if this is not the right place.
