An error is occurring, but where?

[sdingman]

I have a working project already, but I have what seems to me like it is a dumb question to ask, I have searched and searched but can't quite get an answer that makes sense to me. My mega is receiving data on Serial1 at 2400 baud, very slow by almost anyone's standards, but I am getting dirty data consistently and can't seem to find out if the device sending the data is faulty or if my coding is faulty. I've read through Robin's Serial Input Basics, https://forum.arduino.cc/t/serial-input-basics/278284
but the scenarios he discusses don't seem to fit my situation. The data that is coming in is comma separated ASCII from a Battery Monitor is on a constant loop repeating stream with no start or end character. One of the pieces of data is the % symbol, which occurs once per loop, so I search for that. Doing this I have essentially made my own 'Start' character, whose data comes in cleanly every cycle. It's the Current data, whose identification is 'AMPS', that I am getting what seems to bleedover from a different piece of data, that gets taken into the Arduino. The 'V' or Battery Volts might come in as 12.8, and the 'AMPs' will come in as, 128, which I know is an impossibility. How can I troubleshoot this out? With code or something else. To get my data, I'm using:

<
while(!Serial1.available()){}
char a = Serial1.read();
if(a =='%') {
/>

Any links that discuss this sort of thing would be appreciated.

I am getting dirty data consistently

Please post all the code, using code tags, and examples of the "dirty data" (the actual characters received).

[J-M-L]

is that a follow up from Convert streaming ASCII to Text to read Battery Monitor Data - #23 by sdingman

have you built your Serial interface as they recommend?

The bottom example shows how it could be interfaced to another microcontroller for further analysis or processing. The purpose of the signal diode (1N4148) and resistor is to shift the level up slightly so it goes from 0 to 5V instead of -0.6 to 4.4V.

[sdingman]

Yes, that's me from I while back that is exactly like I have it wired. And as I said in my inquiry above, All of the remaining data comes through cleanly. It's only the Current going into or out of the battery that is in question.

can you clarify what "dirty" is?

My encounter with weird data showing up came when I switched from a Mega to a Due. My solution can be seen is the following code:

void fReceiveSerial_LIDAR( void * parameters  )
{
  bool BeginSentence = false;
  char OneChar;
  char *str;
  str = (char *)ps_calloc(300, sizeof(char) ); // put str buffer into PSRAM
  // log_i("Free PSRAM before String: %d", ESP.getFreePsram());
  for ( ;; )
  {
    EventBits_t xbit = xEventGroupWaitBits (eg, evtReceiveSerial_LIDAR, pdTRUE, pdTRUE, portMAX_DELAY);
    if ( LIDARSerial.available() >= 1 )
    {
      while ( LIDARSerial.available() )
      {
        OneChar = LIDARSerial.read();
        if ( BeginSentence )
        {
          if ( OneChar == '>')
          {
            if ( xSemaphoreTake( sema_ParseLIDAR_ReceivedSerial, xSemaphoreTicksToWait10 ) == pdTRUE )
            {
               xQueueOverwrite( xQ_LIDAR_Display_INFO, ( void * ) &str );
              xEventGroupSetBits( eg, evtParseLIDAR_ReceivedSerial );
              //
            }
            BeginSentence = false;
            break;
          }
          strncat( str, &OneChar, 1 );
        }
        else
        {
          if ( OneChar == '<' )
          {
            strcpy( str, ""); // clear string buffer
            BeginSentence = true; // found beginning of sentence
          }
        }
      } //  while ( LIDARSerial.available() )
    } //if ( LIDARSerial.available() >= 1 )
    xSemaphoreGive( sema_ReceiveSerial_LIDAR );
    //        log_i( "fReceiveSerial_LIDAR " );
    //        log_i(uxTaskGetStackHighWaterMark( NULL ));
  }
  free(str);
  vTaskDelete( NULL );
} //void fParseSerial( void * parameters  

I changed if ( LIDARSerial.available() > 0 ) to if ( LIDARSerial.available() >= 1 ) . I have been using this model since my use of the Due with the STM32 Blue Pill and the ESP32. Perhaps it may offer a solution to your issue?

jremington, You requested that I send up a data sample. I do save this data to a microSD card then open them with Notepad.txt files. Apparently this forum won't allow me to upload a sampling of a text file that I put together for demonstration purposes. I did however upload my whole sketch. And as I mentioned in my first post all of the other data come in fine. It's only the Battery Current that is right sometimes. but not repeatable enough for me to fully trust. I'm not sure how to get a .txt document into one of the formats that Arduino.cc will except. Thanks for any comments you may have to add.

I'm not sure how to get a .txt document into one of the formats that Arduino.cc will except.

just paste the text as if it was code (in code tags) directly in line

Idahowalker, Thank you for this little tid-bit from your experience. I will give your suggestion a try.

Thanks jremmington. Well, I can say that the value returned is always a number. I get a data sample every 4 to 5 seconds. For example I'll get a consistent 3.00 for 10 samplings, then I'll get 12.58, which coincidently is what the Battery Voltage is. Then it will go back to 3.14 for several rows of returns, then out of the blue get something like 342.78, that don't coincide with anything else that I receive from this Battery Monitor. Then it will return to Current samplings that look like they are within the range that I would expect somewhere between 20.00 amp positive going into the batteries while charging, to -30.0 at the most that the Inverter might pull out very rarely. I have suspected that the Battery Monitor is to blame, but I don't want to discount the possibility that it's my doing all along, or not.

J-M-L Jackson, I'll give that a try.

[J-M-L]

thx, I dumped that into a spreadsheet and it all looks "OK-ish"

Not sure what you call 'dirty'

[sdingman]

Thanks J-M-L, I import that text file into Excel using comma and space delimiters. The thing is If I want to do any calculation with that Current I can't trust it. I have done a work around though. In Excel I create a Calculated Current column where I use the Watts and the Voltage, which do seem consistent, to calculate the current.

I'm just trying to solve the initial problem of getting dirty current data. Since it is not consistent, I call it dirty. I imagine getting gibberish would be more dirty. I don't want to have to use a work around, when I know something is amiss.

[J-M-L]

OK so the device is sending correct, non corrupted ASCII data but they do not make sense. That's what you mean by dirty.

Sounds like you need to verify proper functioning and if necessary, calibrate the sensor, rather than come up with a "workaround".

[J-M-L]

just to be sure this has nothing to do with your coding or missing data input because of slow stuff elsewhere and buffers filling up. Could you run this

void setup() {
  Serial.begin(115200);   //Serial is the USB cable Serial Monitor connection to computer
  Serial1.begin(2400);    //Serial1 is pin 18 (Tx) & 19 (Rx) from the battery monitor
}

void loop() {
  if (Serial1.available()) {
    byte r = Serial1.read();
    Serial.write(r);
    if (r == '%') Serial.println();
  }
}

and see if you get the same data (open your serial monitor at 115200 bauds)

[sdingman]

Now that is an interesting suggestion. Thanks, I give that a try.

[sdingman]

Thanks jrremington, the Bogart Engineering 2030 has a shunt as its current input. The ASCII signal coming out of this unit is not something that can be calibrated. As I mentioned above, all of the rest of the data is correct and the Current, occasionally correct, but just as quickly it will send out a value that is the look alike of the Voltage , but with the decimal point moved over a position or some other value that is equally arbitrary. I will scour there web page to see if they have any discussion of a problem like mine.

@sdingman

that's what you'll have to qualify. is It what is actually send or is it what your code sees for whatever reason.
Code in #17 should help see what's really being sent
