  @firoozeh one reason a screen will turn black after uploading code is because your code does not contain graphical elements. When using M5BURNER you must use the correct firmware for the core. There are three main cores the core, core2 and coreS3. All three have different firmware and for your unit you must erase and use the Core, Go and fire only firmware

  So write to these sites and get advice! If I have any questions, I immediately write to the consultation! For example, https://gambling-code.cz/casino/nova-casino nova casino, the place where I gamble and at the beginning I often contacted for advice, and now I enjoy games and money to the fullest!

  To control the speed of a 180-degree steering gear in UIFlow, you'll typically be working with a microcontroller like the M5Stack or a similar device. UIFlow provides a visual programming environment that allows you to write code using blocks, similar to Scratch, or you can use Python. To control the speed of the servo, you'll need to adjust the pulse width or angle in your code. Here's a step-by-step guide on how to control the speed of a 180-degree steering gear in UIFlow using blocks: Set up your hardware: Make sure your 180-degree steering gear is properly connected to your microcontroller. Typically, you'll connect the signal wire to one of the PWM (Pulse Width Modulation) pins on your microcontroller. Open UIFlow: Launch the UIFlow software on your computer. Create a New Project: Start a new project or open an existing one, depending on your needs. Drag and Drop Servo Blocks: Go to the "Servo" section in UIFlow's block palette. Drag and drop the "Servo Write Degree" block into your workspace. Configure the Servo Block: Connect the servo block to an event or trigger, such as a button press or a timer. Set the servo pin to the PWM pin you connected your servo to. Set the degree value to control the position of your servo. This is where you control the speed. To control the speed, you can gradually change the degree value from its current position to the desired position over a certain time. For example, if you want the servo to move from 0 degrees to 180 degrees gradually, you can use a loop and increase the degree value in small increments with a delay in between. This delay will determine the speed of the servo. Upload and Run the Code: Upload your code to the microcontroller and run it. You should see your 180-degree servo move according to the specified degree values, controlling its speed by adjusting the delay between position changes. Here's a simple example of how you might control the servo's speed using UIFlow blocks: *# Example UIFlow blocks from m5stack import * from m5ui import * servo0.write_degree(0) # Start at 0 degrees for degree in range(0, 181, 10): # Increase by 10 degrees servo0.write_degree(degree) # Set the servo position wait(0.5) # Adjust the delay to control speed* This example will gradually move the servo from 0 to 180 degrees in 10-degree increments with a 0.5-second delay between each movement. You can adjust the delay to control the speed as needed.

  Thank you for the advice. and, I'm very sorry. the connection and sketch I indicated was wrong. confused. Finally I reffer and correct information are here. Maybe, it is almost dead copy of the refference page. https://lang-ship.com/blog/work/m5stickc-spi-sd-3wire/ M5StickCPlus >>>> SD 3V3 >>>> 3V3 GND >>>> GND 0 >>>> CLK 36 >>>> MISO 26 >>>> MOSI GND >>>> CS #include <M5StickCPlus.h> #include "SD.h" SPIClass SPI_EXT; // PIN配置 enum { spi_sck = 0, spi_miso = 36, spi_mosi = 26, spi_ss = -1 }; void setup() { // M5StickC initialize M5.begin(); M5.Lcd.setRotation(3); // SPI initialize SPI_EXT.begin(spi_sck, spi_miso, spi_mosi, spi_ss); // SD initialize if (!SD.begin(spi_ss, SPI_EXT)) { M5.Lcd.println("Card Mount Failed"); return; } // SD check uint8_t cardType = SD.cardType(); if (cardType == CARD_NONE) { M5.Lcd.println("None SD Card"); return; } M5.Lcd.print("SD Card Type: "); if (cardType == CARD_MMC) { M5.Lcd.println("MMC"); } else if (cardType == CARD_SD) { M5.Lcd.println("SDSC"); } else if (cardType == CARD_SDHC) { M5.Lcd.println("SDHC"); } else { M5.Lcd.println("UNKNOWN"); } // SD volume uint64_t cardSize = SD.cardSize() / (1024 * 1024); M5.Lcd.printf("SD Card Size: %lluMB\n", cardSize); } void loop() { }

  Please tell me about this problem. I used V-Training Service. But this E-mail came. I don't find where any problems in. Are the problems in the jpg files in the folder? Or the number of jpg files is too little?

  There have been issues with the V-Training system provided by M5Stack that they haven't been able to fix.

  Hello, I have a problem with the ESP8266 Audio library, it works fine but when I try to run the command **ledcWrite(ledChannel,6)** to activate a servo, the ESP8266 Audio library stops working. It is exactly the red box in the image

  @holofloh good call, but if the // are removed then the ledc commands are “before” the open curly brackets { of the next line, so I am still confused!

  Hello @jesus-valencia which M5Stack device (Fire, Base, Core2, Stick, Atom, ...) are you using? I am asking because I've tried with M5StickC Plus, M5Stack Base and M5Atom Lite and 2 m of cable between M5Stack device and ENV sensor and it worked just fine. (Note: I used UIFlow for this test.) Care to share your code? have you measured the voltage on the ENV sensor? (Maybe the voltage is ok?) since you have multiple ENV sensors, do all of them fail? (Maybe one is faulty?) have you tried a different power source? (Maybe the USB power supply is weak?) have you tried a different USB cable? (Maybe the USB cable is bad or too long?) Thanks Felix

  @M5Stack After looking at your comment again I figured out what you were trying to tell me (Took me a while to figure it out). I forgot to tell the M5Stack where to look for the text file using /sd/file_name. That took care of the error. Still am unable to print what I want to the screen but at least I'm one step closer.

  Hello @Johnny241 Yes, from what I am reading Ethernet seems to be a bit tricky. I assume you were able to flash and run the Arduino Modbus WiFi example, correct? If so, I'd continue with a simple Ethernet example (not Modbus related) to get familiar with Ethernet and the LAN module. Only then I'd try to modify the Arduino Modbus WiFi example and replace WiFi with Ethernet. Felix

  Hi @rohitpatil I'm afraid our products are only using OV7740 and OV2640so I doubt we can help you, perhaps try the esp32 forum on reddit
