The API of an Arduino library is the public functions exposed to the user. Unfortunately, pins D0 and D1 are the hardware UART (the serial port). Unless the AP is hidden, SSID is displayed along with BSSID (MAC address). Adding Library to Arduino. After the signature is read, you can send other commands to NAND. I wrote the firmware in Arduino IDE. Additional problem is that some manufactureres are ciphering internaly data to hide their anti-wearing bits algorithm (Sandisk is en example ). The data are usualy iverted/XORed and mixed and the are also service data . They have high storage capacity, fast access time and are reliable, usually being able to withstand 100,000 erase/program cycles. 2x 74HC595 Shift Register from Adafruit. Many of the EEPROMS operate on an SPI interface ,this interface is a doddle because you generally do not need to bit bang it, rather you drop the data into the on-chip SPI interface system and the hardware of the microcontroller chip handles it for you. No, the address, data and command codes are all multiplexed onto the same bus. Besides, it is actually a great job interview ‘show and tell’, slap the kit on the table and you are already 80% up on most other candidates.
