#190740 - LCD Shield Responding to: ???'s previous message |
I was going to ask what oins mean. Thanks for explaining.
Yes I will experiment with ferrite beads around the pins they suck and dissipate EMI. I used them to decouple power supply of the circuit. Problem gone now by moving the FPGA and MCUs under the LCD which has big solid ground plane shielding it. Do you have any other idea about EMI gun to test the circuit other than kitchen lighter?. I tried a high voltage spark generator from Amazon, it worked for 2 seconds then broke. Mahmood |
