Write Bytes to and read Bytes from Arduino (Read 4892 times)

Eeprom Page Write (Writing long strings to 24LC256)

EEPROM: it's an older technology to implement rewritable non-volatile memory. It's usually used to store settings and other parameters between resets. This memory supports at least 100,000 writes. You can use the EEPROM library in the stock Arduino library to read from and write to this memory.

Sending 16 bit and 32 bit numbers with Arduino I2C – The

I am trying to send NMEA messages as data over USB-serial XBee to Arduino to control a robot. I can open a Serial object and send data from my PC - observing it with another PC and XCTU. What is the best way to convert the numeric values (uint8) to bytes, and then write them via a Serial objects?

Adding External I2C EEPROM to Arduino (24LC256)

Pixels Each pixel requires just 3 bytes of SRAM to store the color. But those bytes start to add up when you have many meters of strip or a large array.

Adding External I2C EEPROM to Arduino (24LC256) We’re using a 256kbit eeprom which is actually 32kbytes of space. 262,144 bits / 8 bits in a byte = 32,768 bytes. That’s 62 times the Arduino’s built-in storage! If you are using Arduino 1. 0 and above then you need to change Wire. send to Wire. write and Wire. receive to Wire. read.

Learn more on How Stuff Works: How Bits and Bytes Work and the Arduino Bit Math Tutorial to learn more about it. 0x kind of blows the shorter-to-write advantage of hex. 🙃 How many bytes can I send? Technically, you can send 51 bytes. But, the more bytes you’ll send, the more airtime the package will cost you and

Write Bytes to and read Bytes from Arduino (Read 4892 times) CyberCulture. Write Bytes to and read Bytes from Arduino ARDUINO and directly read them and print both writen and read values to processing. Is this possible to directly Serial. write and then Serial. read?I guess it is. . The values that processing returns from ARDUINO are always -1
