I had no problem uploading codes to my arduino for a while, then I found some weird issue. I wrote some code in c++ and imported to arduino sketch.

enter image description here

When I tried to use C1222_EPSEM class (see picture above), i got programmer not responding error and was not able to upload the code. However, when I commented that class out, I successfully uploaded the code without any problem. I have no clue why this happen. Any idea?

it is spamming the serial, then the PC's and USBtoSerial chip's buffers are still full after the reset sent by progroammer PC, then he read a bit of this buffer, it is not the response expected, and voilà.

Please DON'T use image for code
