Debuging UART Tool

Introduction

• Receive and display serial port data.When receiving data at a high baud rate, it is stable, smooth, without stalling, and data loss.
• The data can be sent or displayed as "character string" or "HEX". You can use JavaScript scripts to process the data.
• Automatic frame break function, Automatically insert a line break between two data packets, the data received multiple times will no longer be crowded together, it is easier to distinguish the data each time. Make the inspection and analysis of the data clearer and more intuitive.
• Waveform display function. The data sent according to the protocol can be displayed as a waveform. Supports simultaneous drawing of multiple waveforms. The ordinate is automatically adjusted to facilitate observation. And support the waveform review function and screenshot function.
• Support multiple character encoding "ASCII","GB2312","UNICODE","UTF-8","BIG5","shift_jis"
• The serial port baud rate can be selected as 300bps-1500000bps. (Hardware support is required when the baud rate>115200). Support custom serial port baud rate at the same time.
• Support extended commands, up to 600 groups of custom commands. Convenient for debugging equipment.
• Custom command list, Combine multiple extended commands into a list. Just click once to send, automatically execute each command in the list.
• Perfectly adapted to high score screens. There is no blurring problem for most software in high score screens.

Get a lot of users alike

• This application is well suited for serial monitoring, full of nice features such as the capability to dislay and send HEX, etc...
• The best terminal app for serial debug!
• It helped me with my Embedded Systems SERCOMM debugging for ADA language. I sometimes also use it as alternative to arduino IDE Serial monitor.
• Everything worked just like it should. One of the best serial port programs I have ever used. If it could open multiple ports in the same main window, it would be the best.
• Good use Work has been in use for a year
• Excellent app, does what I need for my arduino
• Works great. Love it. It took me a while to figure out some of the UI but eventually I have discovered everything I need. One suggestion... adding support for color escape codes would be awesome. I would be glad to pay for it as an add on.

Use scripts to aid in analyzing data

Use the js script to analyze UART receive data and draw graphics

js script

(
    function main() {
        var str = receive.get();          //Read the Received string
        receive.write(str);               //Prints the received characters
        receive.write(" -> ", "red");     //Print the arrow
        var buf = StrToBytes(str);        //Turn the received hex string into an array.
        var val = BufToValue(buf, 7, 2);  // CO Turn the array into integers by index and length
        var val2 = BufToValue(buf, 9, 2); // HC
        receive.write(val + " ", "Green");//Print the converted integer
        receive.write(val2, "DarkRed");
        chart.write("HC=" + val + "\n");  //Draw to waveform interface. The name is HC
        chart.write("NO=" + val2 + "\n"); //Draw to waveform interface. The name is NO
        receive.write("\r\n");            //Print line breaks for easy observation.
        return;
    }
)()

// Turn the data in buf into an integer.
// buf array
// index : The starting position in Bytes
// len : Contains the number of bytes
function BytesToValue(buf, index, len) {
    var val = 0;
    for (var i = 0; i < len; i++) {
        val = val << 8;
        val = val + buf[i + index];
    }
    return val;
}
//Turn the received hex string into an int array.
function StrToBytes(str) {
    var index = 0;
    var buf = new Array;
    for (var i = 0; i < str.length; i++) {
        while (str[i] == "«" || str[i] == " ") { //Remove useless characters
            if (i < str.length)
                i++;
        }
        buf[index] = parseInt("0x" + str[i] + str[i + 1]);// Turn the string into a number.
        index++;
        i += 2;
    }
    return buf;
}
