Updated to version 1.1
I have tested v1.0 with arduino nano and it does not really work. It seems the serial converter has problems on my board but must not on all boards. If a arduino do not work you have to change in the script the line "Serial.begin(115200);" . Comment with a leading // the line and uncommend the line "Serial.begin(9600);". Then upload the new arduino script and gice it a try. There is nearly no difference with lower baud rates. Will test this code with other boards. Added serial port error count to verify a stable connection. Also the plugin of X-Sim is updated and now stable. There was many errors that are now fixed.
