Will u8g2 be an option? I once wrote a small setup guide which also includes the ST7920: https://github.com/olikraus/u8g2/wiki/setup_tutorial. There are one thing to consider: There is a parallel and serial mode for the ST7920. Which mode do you want to use (I suggest serial SPI mode). Then: You should create a mapping table for your connections. I did this in the above mentioned setup tutorial README.md. U8g2: Library for monochrome displays, version 2.

  1. U8g2 exactly includes the same print command and will put the output on the display. Oliver. Skydome December 9, 2017, 12:18pm #5. due to I'm still at the beginning getting into C++ and therefore asking for a template, the last answer linking to serial.print isn't a help at all. anyway, thanks for your response! Could someone please post an example how to solve the task as described in the.
  2. Arguments: u8g2: A pointer to the u8g2 structure. x, y: Position of the first character on the display. s: UTF-8 encoded text. Returns: Width of the string. Note 1: This drawing function depends on the current font mode and drawing color. Note 2: Use the print function to print the value of a numeric variable. See also: setFont drawStr prin
  3. I will show you how to install and use u8g2 library. You can also check how library works on 128x32 OLED screen. Data that are displayed on screen are voltag... You can also check how library.
  4. This is a choice from common U8G2 display types, if you're not familiar with these, you may need to run one the U8G2 packaged examples to work out which option is right. Not all options are supported by quick start, but most common ones are. Should you need to use one of the unsupported cases, use the manual configuration option instead. Display rotation. You can preconfigure the display.

The U8g2 library is an open source project for driving monochrome displays. This video tutorial illustrates how to use that library on an ESP32 using ESP-IDF. The video can be found here: In the video we reference a hardware abstraction layer that maps U8g2 library operations to the ESP32 hardware I just installed the u8g2 library and was trying to load and run Examples. None of the examples will compile without this error: 'u8g2' was not declared in this scope. You need to uncomment the correct display constructor as adviced in the comments of the examples This example was tested on 2016-06-11 and it failed to compile on common Arduino boards The U8glib user reference page mentions a couple of ways to print the value of a number using ASCII characters.. Eg, following the idea at the second mention of sprintf at above link:. char buf[9]; sprintf (buf, %d, a); u8g.drawStr(33, 33, buf); Edit: The above follows the example at the link, but I've struck it out because in general snprintf is safer than sprintf Well its not me that is using it incorrectly then. the example hello world uses it like this: u8g_SetFont(&u8g, u8g_font_fub49n); u8g_DrawStr(&u8g, 0, 60, hello world); in my #1 post i just changed hello world to a variable speed. which is obviously wrong but i was just trying to explain what i want to do. The documentation you have pointed me to is for arduino i think. i am using the avr.

The examples/SensorFusion folder contains a little sensor fusion example using a BMP180 barometer and LM35 temperature sensor. I have run this example on an Arduino Uno and a Teensy 3.2. The BMP180, being an I^2C sensor, should be connected to pins 4 (SDA) and 5 (SCL) of the Uno, or pins 18 (SDA) and 19 (SCL) of the Teensy. For other Arduino boards, consult the documentation on the Wire. But I have tried several example sketches which are included in U8g2 and they all worked very well with my SH1106 OLED. So I am happy with that. However when I use one of your OLED projects which are written for the SSD1306 OLED, I have to rewrite all relevant code in your sketch, assumed I could manage that (no experience at all), to make it suitable for the SH1106 with the U8g2 library.

The hardest bit is picking the right device driver for your particular display; there are several variants on the SSD1306, for example. In the u8g2_esp32_hal.c file, make sure that the init code in the i2c callback function properly clears the i2c_config_t structs, or sets every element explicitly, otherwise random crashes can and will happen.

The WS2811 is a LED controller chip, requiring external R,G,B LEDs. At 5 V uses one LED per channel, at 12 V three LEDs. This is why 12 V VS2811 strips have three RGB leds per IC, and control in those bunches of three instead of one. WS2812 is basically a 2811 embedded inside a 5x5 mm RGB LED case 使用 u8g2 package 需要在 RT-Thread 的包管理器中选择它,具体路径如下: RT-Thread online packages peripheral libraries and drivers ---> [*] U8G2: a u8g2 package for rt-thread [*] Use hardware spi (spi1) spi bus name (NEW) (spi10) spi device name (NEW) [*] Use hardware i2c (i2c2) i2c device name U8G2 Examples --->
