Maybe using I2S is a better solution for large strings of addressable LEDs as you can assign DMA.
DMA doesn't work very well with RMT

Perhaps you need to settle on a stable option that will work everywhere, or make a choice of option?

Works stably.

Alex P

I guess I need to connect the logic analyzer to it to see if this is a timing issue. The reason I asked to test the later build is that there has been some changes to how USB serial is handled on ESP32-S2. So you have ESPEasy console also enabled on the USB-CDC port? You can disable the ESPEasy con...

Where is the start of the string? Can you also try the latest test build I posted here: https://td-er.nl/ESPEasy/latest/ This one has a more recent ESP-IDF version.

Alex P

I use NeoPixel (7-Segment) and artifacts are constantly present. I use a level converter. I tried to turn on NeoPixel Matrix, NeoPixel Ring Clock, NeoPixel (Candle). Only on the last one (Candle) there are no artifacts. Build: ESP_Easy_mega_20240919_neopixel_ESP32s2_4M316k_LittleFS_CDC_ETH Sep 19 20...

I noticed this on two devices on these builds

Alex P

Also there isn't a perfect 1-to-1 conversion for binary floating point values to decimal and back. Some number simply cannot be represented in binary floating point representation and thus cause rounding errors. Still, I don’t understand why the number 23.6 from the sensor, presented in binary form...

Ath wrote: ↑11 Jul 2024, 12:19 You should use that formatted version when displaying the value using "7dtext,[var#5#D.1]H". After assignment it will be still stored as a float, with all rounding/accuracy issues described above

Thanks for your idea. Everything worked.

Thanks for your clarification. I understand your point.

Alex P

No, the problem is not in comparison. Problem with display output. I don’t understand why, when assigning the value 23.8 to a variable, it turns out to have 23.799999.
Let,9,[var#5#D.1] I tried the same thing, it doesn't cut

Alex P

the variable v4 v5 is assigned the temperature value with one digit after the point; in system variables it is displayed; it is sometimes displayed with a much larger number of digits and is displayed in text mode in the same way.
in the sensor settings there is one digit after the dot

Alex P

Thanks for the explanation. Now I understand that the rows are based on tiles and not the size of the matrix.

Alex P

After installing the level converter, the main problem went away, only periodically appearing colored artifacts remained throughout the field. It is also not clear why there are not 4 text lines when rotating, since the matrix is a multiple of 8x8?

Alex P

Yes. Certainly

This is a zigzag structure. When I asked about display rotation, I meant lines or (lines of text). How many should there be for my matrix? neomatrixcmd,settext,2,text cannot be displayed?

Alex P

OK, thank you. There is still a question about rotating the display 90 degrees, what will happen to the lines? With a 32x8 rotation, how many lines should there be?

Alex P

This is not possible, the matrix consists of 8 pieces of tape with 32 LEDs connected in a zigzag, it is impossible to get an image on 16x8 or 8x8. And when you rotate the display 90 degrees, the ticker works fine, but the screen still remains on 1 line. I think the problem is not related to the numb...

Alex P

In fact, I have 32x8. I tried the 32x4 and 32x16 options. I can't do 16x8 without soldering.

Alex P

I've already done all this. And he told about the results obtained. Pay special attention to the last result with 32x16.

Alex P

I already tried 32x4, I don’t understand how to make 16x8 without cutting and resoldering. I tried to put 32x16 although in fact I have 32x8 and 1 line started working fine for me. It turns out that the second half always does not work when running the line starting from 32x4.

Alex P

Understood. But to do this you will have to cut and resolder the tape. Now I have it from 8 pieces of 32 LEDs.

Alex P

How to change the grid size? I tried changing the dimension of the 32x8 matrix to 32x4. But before that it worked for the top 4 lines. But I don’t want to cut the tape for a different configuration yet.

Alex P

I haven’t used a level converter yet, I just installed a resistor. I tried the same controller with a different firmware, the creeping line comes out correctly. I reduced the matrix for testing on the advice of TD-er, perhaps he meant something else. I don’t understand what the software difference i...

Alex P

ESP_Easy_mega_20240331_neopixel_ESP32s2_4M316k_LittleFS_CDC I didn't start at all. if you make a 32x4 matrix, then half of the font runs in 4 lines, the bottom 4 are empty. When outputting via neomatrixcmd, settext, in the rules of different lines not running, everything is fine. tell me how to check.

Alex P

Build: ESP_Easy_mega_20240331_neopixel_ESP32s2_4M316k_CDC assembled a 32x8 matrix, When displaying a static image, everything is fine, as soon as scrolling is turned on, the top 4 lines run normally and the bottom 4 lines run in a different color from the garbage.

Alex P

You are right that this affects the consistency of levels, but unfortunately it did not help. I think that this is not a hardware problem, because in the next topic, when connected to Arduino, everything worked. I'm waiting for the Arduino nano to arrive for testing.

Should the default data be displayed here, or is it necessary to somehow read the sensor using rules? How to properly check the sensor?

viewtopic.php?t=9695
same problem

Alex P

I applied 5 volts, output 3.3 shows 3.3 volts

Alex P

Vin goes to the stabilizer 3.3 volts. the P050 documentation the same scheme

Alex P

P050 documentation In the examples on the screenshot, 0 values are also indicated. Maybe I'm not looking there? What should a good job look like?

Alex P

there is nothing protective, and most importantly, there are no reading events in the log

Alex P

Can't run Color - TCS34725. Tested on ESP8266, ESP32S2. ESP_Easy_mega_20230623_collection_F
Scan for I2C devices finds I2C Addresses in use 0x29, in the data it displays 0 in the log there is also nothing.

Alex P

I have not yet learned how to make my own builds, I download the finished *.BIN

Alex P

An error has crept into the chip name correct ZD25WQ80

Alex P

Yes, ESPEasy cannot write the settings file.
It seems to me that the problem here is the same as with PUYA, ESPEasy does not know this type of flash, and cannot apply the appropriate algorithm.

Alex P

I flashed Wled, Tasmota, they work fine.

Alex P

Alex P

The rules themselves are not followed, there is no reaction.

Alex P

Rules do not work on my ESP-01S when loading assemblies newer than Easy_mega_20220328_normal_ESP8266_1M

Alex P

When you enter the command dn, dt, the display only flashes for a fraction of a second.

Alex P

Thank you. While I use through dtext. But it seems to me that there is some difference in hardware output between auto and manual mode.

Alex P

WiFi led feature is disabled, it does not prevent the display from displaying information. Only the 7dt function does not work.

Alex P

ESP-01S

Alex P

How to use the 7dt command. At the same time, my display just flashes. At the same time, 7dtext displays the temperature normally. На шине DIO-Pin у меня подключен LED.

I flash them with flash_download_tool in DOUT mode. I can advise you to flash in different modes and watch debugging in COM.
