I compile after selecting Arduino Uno and AVRISP MKII.
Uploads from PC to board are at 57600bps. This limitation suddenly appeared after that I updated Arduino from an older release to the most recent available. This happened to other people too. Somewhere, I read that the solution was setting the upload speed at 57600 in the file "boards' (path: C:\Program Files (x86)\Arduino\hardware\arduino\avr). The trick worked to an extent because uploads work again but the communication between board and Serial Monitor degraded to 2400bps but only on certain boards such this one.
This is a different chip, not fully compatible with arduino AVR toolchain.
You must install a special package to support it, otherwise you will constantly encounter a weird behaviour.. Ask seller for link to software for the chip.
No EEPROM but there is the ability with ARMs to do IAP (In Application Programming) which writes into flash. This could be used for non-volatile storage but someone will have to write the code. Maybe the Arduino guys have converted the EEPROM library to do this.
Said that, the idea of using the Flash memory is not bad, and using the EEFC device of SAM3X should be not too hard to create a simple FLASH library, maybe with a slightly different API from EEPROM that take in consideration the limits above.
Because the arduino is a development platform. However people seem to think that all trivial things should be presented as a library. There have been many years of unnecessary trivial function library development for the existing system, you can't expect that over night.
I have created a library for Arduino Due at GitHub - sebnil/DueFlashStorage: DueFlashStorage saves non-volatile data for Arduino Due. The library is made to be similar to the EEPROM library.
The library is made to be similar to the EEPROM library. It will save non-volatile data but the flash storage is reset every time you upload a new sketch to your Arduino. Except for that exception it works the same as EEPROM for the older Arduinos. Remove power or press the reset button, the data will still be there.
Very recently, I downloaded the Arduino IDE 1.6.9 and the EEPROM library is not there, it is not on the list nor is it in the libraries folder in Program Files(x86). It is missing, how can I find it and put it back?
It's located at hardware\arduino\avr\libraries\EEPROM inside of your IDE installation folder. The reason it's there instead of in the libraries folder is because it's an AVR specific library so it's part of the Arduino AVR Boards core.
Ok, I have this all sorted out. Turns out the IDE only shows the libraries available for the board you are trying to work with. I had the board set to the Due's programming port. I switched it to the Uno and the EEPROM library is now there. After figuring this out, that's actually a nice feature to have. Im just bad at remembering to switch boards. =
Writing and reading EEPROM is possible to do without a library. Take a look at the datasheet of the ATmega328P to find an example: On page 25 / 26 there are example codes for reading and writing both in assembler and C. They do wrap it in a function but as I said in a comment if you only have place in your code where you would like to access EEPROM you can put the code there without duplication. These functions write and read one byte at a time, so if you want to store larger datatypes (a 16-bit integer for example) you already need to call the routines more than once.
ChatGPT says this is because the EEPROM.h library was changed recently and all these functions have been removed with version 2.0.0, but I can't find any information about this and the official documentation still has these functions, so I'm thinking ChatGPT may have just made that up.
To use the EEPROM library, a header must be added, and the maximum size of the current EEPROM is 512bytes. Since the EEPROM library has ported what is supported in Arduino, the basic usage method is the same as that used in other existing Arduino boards. For more information on how to use it, please refer to the Arduino site.

ESP8266WiFi library has been developed basing on ESP8266 SDK, using naming convention and overall functionality philosophy of the Arduino WiFi Shield library. Over time the wealth Wi-Fi features ported from ESP8266 SDK to this library outgrew the APIs of WiFi Shield library and it became apparent that we need to provide separate documentation on what is new and extra.
Wire library currently supports master mode up to approximately 450KHz. Before using I2C, pins for SDA and SCL need to be set by calling Wire.begin(int sda, int scl), i.e. Wire.begin(0, 2) on ESP-01, else they default to pins 4(SDA) and 5(SCL).
An ESP8266 port of SoftwareSerial library done by Peter Lerup (@plerup) supports baud rate up to 115200 and multiples SoftwareSerial instances. See if you want to suggest an improvement or open an issue related to SoftwareSerial.
This library exposes the ability to control RC (hobby) servo motors. It will support up to 24 servos on any available output pin. By default the first 12 servos will use Timer0 and currently this will not interfere with any other support. Servo counts above 12 will use Timer1 and features that use it will be affected. While many RC servo motors will accept the 3.3V IO data pin from a ESP8266, most will not be able to run off 3.3v and will require another power source that matches their specifications. Make sure to connect the grounds between the ESP8266 and the servo motor power supply.
DHT-sensor-library - Arduino library for the DHT11/DHT22 temperature and humidity sensors. Download latest v1.1.1 library and no changes are necessary. Older versions should initialize DHT as follows: DHT dht(DHTPIN, DHTTYPE, 15)
UTFT-ESP8266 - UTFT display library with support for ESP8266. Only serial interface (SPI) displays are supported for now (no 8-bit parallel mode, etc). Also includes support for the hardware SPI controller of the ESP8266.
FastLED - a library for easily & efficiently controlling a wide variety of LED chipsets, like the Neopixel (WS2812B), DotStar, LPD8806 and many more. Includes fading, gradient, color conversion functions.
ESP_EEPROM - This library writes a new copy of your data when you save (commit) it and keeps track of where in the sector the most recent copy is kept using a bitmap. The flash sector only needs to be erased when there is no more space for copies in the flash sector.
Arduino offers a native EEPROM library that allows us to easily deal with the EEPROM of the ATMega328 (or whatever Atmel µC your Arduino is running). Writing and reading values is as simple as following :
EEPROM Write/Read StringTo Write a String in ESP32 EEPROM, use the following function from the EEPROM library.12// Write a String starting from a specific address locationEEPROM.writeString(address, &myString);
So I have been working for a while now on a controller for the vegetable oil system in my vehicle. I am fairly new to programing and am enjoying teaching myself with an arduino. I have an arduino nano 32 that I plan to use for the project. I have gone through many different variations and different ways of doing the logic. Some that work and then get to complicated and start not working and others that just don't work. I am just wondering how any of you would go about doing this? I don't need a full code per-say as I am trying to do this mostly myself but maybe some examples or different ways to get me started on the right path.Here is what I have up until the loop
