When I search for the SPI.h library, I get a bunch of hits, but none of the library’s seem to be for i2c communication with the Adafruit Led Backpack. I do, I have a couple of things wired to the MEGA: Adafruit BME680 (temp pressure) using the I2C interface (SCL wired to 21 and SDA wired to 20) and a KC-30 CO2 sensor wired to pins 10 and 9. This chip is powerful and useful to have when you want to use Python (for example) to quickly iterate and test a device that uses I2C, SPI or plain general purpose I/O. NEW GUIDE: Programming SPI flash with an FT232H breakout. Remember the SPI flash library is built to have the same functions and interface as the Arduino SD library so if you have code or examples that store data on a SD card they should be easy to adapt to use the SPI flash library, just create a fatfs object like in the examples above and use its open function instead of the global SD object's open function. Well, now your computer can talk to devices using the Adafruit FT232H breakout board! I just cannot communicate a second time to the WiFi, after having used another SPI device (Flash). This chip from FTDI is similar to their USB to serial converter chips but adds a 'multi-protocol synchronous serial engine' which allows it to speak many common protocols like SPI, I2C, serial UART, JTAG, and more! You should see the serial monitor display a message asking you to confirm formatting the flash. You signed in with another tab or window. Be aware too the fatfs_format and examples below are not compatible with a CircuitPython-formatted flash chip!

Resources. To use the flash memory with Arduino you'll need to install the Adafruit SPI Flash Memory library in the Arduino IDE. Add to Cart. Here's how the sketch checks if a boot.py file exists and prints it out a character at a time: Notice the exists function is called to check if the boot.py file is found, and then the open function is used to open it in read mode. It can also be used for communication between two microcontrollers. However there are more advanced read functions you can use too--see the fatfs_full_usage example or even the Arduino SD library documentation (the SPI flash library implements the same functions). SPI Flash Standardization The good news is that just about every 8-pin Flash chip has a standard pinout and SPI interface, these tend to have the number 25 somewhere in the beginning of the part number.
