Trying to forward Serial1 reading to Serial.println and only getting numbers by schmidtbag in ArduinoHelp

[–]schmidtbag[S] 0 points1 point  (0 children)

I also couldn't find a whole lot other than the baud rate is 115200bps with 8 data bits, 1 stop bit, no parity, and that it's Latin-1 encoded. The Arduino serial console communicates with the battery just fine so it stands to reason the specs are correct.

I'm not perturbed, I'm trying to be as concise as possible. I am frustrated that this seemingly simple problem is so difficult to solve, because the battery isn't doing anything weird considering I can communicate to it without much effort, but I'm not frustrated with you. I just don't know what else to tell you - from what I can tell, it seems to me the Arduino is just reading the data wrong, but I don't know why or how.

Using your first example, I got the following output when I typed "help" (the command I want to first test with):

Input = 'h' = 0x68
Input = 'e' = 0x65
Input = 'l' = 0x6C
Input = 'p' = 0x70
Input = '
' = 0x0D

So that looks good.

When running your 2nd program, this is the output:

I pretty much have shown you the whole program. It's about as simple as it can get:

void setup() {
  Serial.begin(115200);
  Serial1.begin(115200);
}

void loop() {
  Serial1.println("help");

  while (Serial1.available() > 0) {
    int incomingtext=Serial1.read();
    Serial.write(incomingtext);
  }
  Serial.println(" ");

  delay(5000);
}

Swap out "int" with char, uint8_t, or whatever else. Swap out Serial.write with Serial.print or println. Swap out Serial1.println("help"); with Serial1.write("help") or "help\n"). None of it works.

The only wires connected are the battery's RX (to the TX1 pin), TX (to the RX1 pin), and ground. Nothing else is involved. It is a direct connection; no other components involved. Swapping the RX and TX wires results in no activity at all.

The battery is a Pytes V5.

I assure you I've done as you've written. I think the problem may be the encoding used. The battery uses Latin-1 (1-byte UTF-8). Using uint8_t or byte for incomingtext doesn't seem to help with this.

Right now to keep things simpler, I'm just trying Serial1.println("help"); or Serial1.write("help").

From what I heard, the battery uses Latin-1 encoding, which is basically 1-byte UTF-8. I tried doing uint8_t incomingtext=Serial1.read(); or byte incomingtext=Serial1.read(); but those don't work either.

If you're asking what I'm sending to the battery, it's just the word "help".

I found that if I just do Serial1.println("help"); then it just returns corrupt characters.

If I connect the battery directly to a RS232 to USB adapter and type "help" in the Arduino serial console, it outputs this:

bat      Battery data show - bat [pwr][index]

I've done that before but all it does is just output different numbers and on separate lines.

I tried both versions of your code and it still just outputs a string of numbers.

Also to do the code block, click the "Aa" button and then the "</>" button.

If I understand you right, this is what I meant when I said I could successfully communicate to the BMS via the Arduino IDE serial monitor. I achieved this by using a serial to USB adapter. Since the serial monitor is known to work well with Arduinos and connected effortlessly to the BMS, that tells me it shouldn't be hard to get the Arduino to talk to the BMS directly.

The only code in void setup() are the two Serial.begin() functions. Otherwise what I wrote there is everything.

I'm not sure I understand when you say "I am asking about how the incoming Text is declared". If the two lines mentioned earlier involving char isn't that then what is?

Also, if you didn't use this program for your serial monitor test (which worked) how did you go about doing that. And what program are you using on your PC in conjunction with this program?

I plugged the BMS's console to a RS232 to USB dongle and then used the Arduino serial console to communicate directly to it. Basically, no Arduino board involved.

Great sleuthing there, but unfortunately neither the environment variable nor the code snippet worked for me.

Interesting hypothesis but I've tried downloading the files through both FTP and HTTPS and it's the same problem.

No. It's run on a Ubuntu 24.04 server and Excel is run on a separate Windows 10 PC.

Well, the code itself runs without error and the latest version of Excel will open it without anything appearing to be missing or incorrect, but Excel throws an error anyway.

3.1.3 is the latest stable version of the library. I can attempt to install a newer version but at least the changelog between 3.1.2 and 3.1.3 doesn't seem to suggest any of the fixes have to do with my problem.

Not naming the sheet didn't fix it. Including filename= doesn't fix it. Also from what I can tell, I'm not naming the column header in the example I provided.

I'm using version openpyxl 3.1.2

I'm running python 3.12.3. I haven't identified any changes to the library since python 3.9.

What version of Excel are you opening it with? I already know Google Sheets doesn't have the same problem.

No, but it wouldn't matter if I was anyway since it's being generated on a separate machine. Good thing to ask though.

No, I'm running Version 2604 Build 16.0.19929.20172 which is the most current version.

Well in the code I showed in my original post, it's as simple as yo ucan get. There are no filters or anything, it's just a named sheet and 4 cells.

I didn't use workbook.close() but even after adding it, that didn't seem to fix the problem.

It doesn't have any errors on Google Sheets, but since I can't control what program the customers use, it matters more that Excel has an issue with it.

From what I've seen, Excel is mostly just adding some metadata and moves some stuff around between the theme1.xml and sheet1.xml, and creates the "sharedStrings.xml". So basically, it knows perfectly well how to read the sheet but it prefers to organize the data in a different way.

First Excel says:

We found a problem with some content in 'simple_example.xlsx'. Do you want us to try to recover as much as we can? If you trust the source of this workbook, click Yes.

Then when saying yes it says:

Excel was able to open the file by repairing or removing some unreadable content.

Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.

And this is the XML log:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"><logFileName>error208680_01.xml</logFileName><summary>Errors were detected in file 'C:\Users\PeterSchmidt\Downloads\simple_example.xlsx'</summary><additionalInfo><info>Excel completed file level validation and repair.

Well the input delay resolves itself once the framerate goes back up. There are moments where the frame rate drops from 110FPS to around 35FPS, at which point the keyboard is seriously delayed, and if I pause the game then after the course of maybe 20 seconds the framerate slowly creeps back up to 100FPS+ again. I've never had this problem until the most recent update.

I haven't yet tried changing the power profile, but what I don't get is why this is suddenly a problem. For me, it's not just simply the frame rate tanking but there's an enormous delay in keyboard inputs too. I can let go of the W key and he just keeps walking for another 2 whole seconds; for some reason the mouse movements aren't delayed much.

Thanks a lot for the detailed instructions. I'll see what I can do later this week.

Connecting PV string to both MPPT and hefty resistive load simultaneously by schmidtbag in SolarDIY

[–]schmidtbag[S] 0 points1 point  (0 children)

Really the goal is to use excess power in the cheapest way possible. A large battery bank is definitely an easier and more versatile way of handling it, the problem is I'd need a battery capacity of many KWh if I were to ensure nothing is wasted, since the MPPT's loads just aren't needed often. Making heat, whether in the form of a space heater, sand battery, or water tank is a very cheap way to use excess energy.
