kandi X-RAY | ssd1306 Summary
SSD1306 driver is Arduino style C/C++ library with unicode support. The library can be compiled for plain Linux (for example, raspberry spi), or you can use it with plain avr-gcc compiler without Arduino IDE. It supports monochrome and RGB oleds and has debug mode, allowing to execute code on PC, using SDL2.0. Initially the library is intended for very small microcontrollers (with a little of RAM). It was developed to use as few resources as possible, but still has powerful capabilities (NanoEngine), allowing to develop nice animation. It works on any powerful devices like raspberry pi, esp32; and can be easily ported to new platform.

QUESTION
I'm doing this on esp8266 with micro python and there is a way to clear OLED display in Arduino but I don't know how to clear display in micropython i used ssd1306 library to control my OLED
and this is my error I've written a code that prints on OLED from a list loop, but OLED prints it on the text that was printed before it (print one on top of the other not clear and printing) 7

QUESTION
I'm trying to print the return value(WiFi.localIP) on my display from the library ESP8266WiFi. But I'm getting an error. For the display I'm using the SSD1306 library.
The purpose of this is to print the IP adress of the ESP8266 on the display.
ERROR:

- You are affecting a pointer to initialize a no-pointer variable (with the '&')
- The compiler does not manage to cast an object IPAddress in String.
The use of a function "to_string" would be better.
QUESTION
I'm currently working on a sensor box, that displays the sensor data non stop in the loop of a ESP32 Node MCU on a SSD1306 Display, connected over I2C (21 and 22). But then the display does weird stuff.
I can't share all of the ESP32 Code right now, but this should be all the needed stuff anyways I guess:
...ANSWER
Answered 2021-Sep-16 at 07:40Apparently the problem was, there were too many devices connected over the same I2C bus. So what fixed this:
Instead of soldering Display, two Sensors and a real time clock to GPIO 21 and 22, I soldered the display to GPIO 32 and 33.
Added
Wire1.begin(32, 33);to setupChanged constructor of display to
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire1, -1);
I guess the display stops working as soon as there is too much traffic on the bus. So this was not a memory problem
QUESTION
I have an issue with:
">OKMemoryError: memory allocation failed, allocating 13759 bytes"
I have tried ESP32 4MB but also 16MB flash memory so there is no way, it can't handle this code. I believe it's because of the "ZERO", "ONE", "TWO" variables because when I comment them out and keep just "ZERO" for example, it's working fine. But.. I mean c'mon, the whole file is 38kb, and the memory of the ESP32 is 16MB, it must handle it...
What's the issue?
...ANSWER
Answered 2021-May-11 at 07:41Your program runs out of RAM. The ESP32 has 520 KiB of RAM, out of that 328 KiB is used for data and 192 KiB for instructions. This has to fit the Python interpreter (which is a memory-hungry program itself) and all that your script uses.
Here you're creating 3 huge arrays of 32-bit integers which together allocate 30% of the entire data RAM (each takes 128x64x4=32KiB to store just 1KiB of frame data). That's not how it's done. Also I have no idea what's inside the SSD1306 drivers you're creating 5 of - maybe frame buffers of their own?
If you're certain this is the way to go, get the ESP-WROVER-B module which has 8 MiB of added PSRAM.

QUESTION
Prologue
I finally got around HW incompatibility between AT32UC3xxxxx and SSD1306 OLED I2C display (both have HW bugs making them incompatible) allowing me to use HW I2C at 400KBaud (~26.6ms per frame). So I decided to rewrite my old driver for this LCD to make advantage of the new speed by adding also filled surfaces (triangles,quads) instead of just lines and patterned lines (which I already implemented).
The problem is the display is 128x64 pixels but no colors or shades of gray just BW on/off
So in order to for example render rotating cube I need to distinguish the surfaces somehow. I was thinking about randomized filling pattern where surface is filled to some percentage instead of color.
Here my current code (Whole lib but without bugs its working as should):
LCD_SSD1306_I2C.h
...ANSWER
Answered 2021-Mar-09 at 10:06I managed to get this working. I ended up with hardcoded 17 shade patterns of size 8x8 pixels (created manually in Paint). These are the shades:
From there I just use x,y of rendered pixel mod 8 as coordinate in the LUT of shades. This is the result:
As you can see its much more better than PRNG based shading. Here the updated code:
QUESTION
Noob question: I'm trying to learn about UART on an ARDUINO. I wrote some very simple code and for some reason, i can't make the receive() function work. I don't think it fetches the data from the UDR register. I'm using a small OLED display and i want to print the received data to it. No data is being printed to the display, when i run the code. I connected the ports TX1 and RX1 with a wire on the board. I tried finding youtube videos and have been reading alot. Appearently not enough. Any ARDUINO expert who knows what to do?
...ANSWER
Answered 2020-Apr-27 at 02:18It looks like you never call initUART1().

I am trying to send messages from Pure Data to Python (to display on an SSD1306 OLED). Someone suggested I use sockets. They also provided the following Python code:

Answered 2020-Apr-18 at 16:16You can use Python's socket library to connect to a Pd patch that sends information through [netsend]. Here is a working minimal example. In Pd, create a simple patch that connects a [netsend] to a port on your localhost network:
