Arduino Code Request - Byte Stream to Array

[Chet T16]

Looks good 
That state machine should allow you to read in the data and do whatever you want with it.

Thanks for the help (everyone!)

I've added in a loop to print the array to a software serial port so i'll give it a test and see what happens

MyData[Counter-4] = ReadByte;
Counter++;

ops, you are right, i should imaginate and have the picture flowing in my mind but still your previous code is not 100% right, so maybe we all got some mistake. thats why i used to extend the possibility, such as...

Code: [Select]

if ((Counter - 4) <= 38) {
MyData[Counter - 4] = ReadByte;
Counter++;

if ((Counter - 4) >= 38) {
DisplayAndOrClearData(); // another function
Counter = 0;
}
}

Dammit, a hardware issue somewhere

To read the data i need to invert the signal from the ECU which i use this circuit for



I use this with an FTDI cable to read the stream directly and its fine. When there is data coming the LED flashes but when i connect Rx to the arduino rx pin the LED goes out. I just checked at theres 5v at the arduino rx and tx pins. Whats that all about??
