The program function is pretty much the same but with a 30us delay at the end, this is because the data-sheet details how there are some operations that happen after a byte is programmed and so we must wait for these to be completed. These functions allow the output of data but now we must make a different one for reading/input of data. The byte on DQ0 to DQ7 is then read and OE# is set back to HIGH. So if the input is ‘E’ it will call the function to erase the chip, if the input is ‘R’ it will read and print the data at address 0x0000 or if the input is ‘W’ it will program 0x3E to 0x0000. Data Storage Arduino Library for controlling the SST Nor Serial Flash SST25VF family. This library provides Arduino support for the 64-Mbit Quad-SPI NOR Flash memory MX25R6435F connected to the Quad-SPI or Octo-SPI interfaces of a STM32 board.

On top of that, the Portenta H7 module adds 8 MB of off-chip SDRAM as well as a 16-MB QSPI NOR flash chip. I can’t wait to read the Part 3 of this tutorial. In our program loop we simply want to check for serial data and if there is some, we read the first byte and pass it into a function to decode the command. Arduino library to support the X-NUCLEO-53L1A2 based on VL53L1 Time-of-Flight ranging sensor with advanced multi object detection C++ BSD-3-Clause 1 0 0 0 Updated Sep 24, 2020. This is because the addresses are much longer than a byte(8-bit) or an int(16-bit) so a long(32-bit) must be used to accommodate for the 19-bit addresses and I made it unsigned just as the addresses are always positive values. This time, I'll deal with the limitation of the small MCU and read the NAND signature. Multiple options in one board. Now we can just set-up the control pins and call the relevant functions in the setup() function. I put a delay at the end just to ensure the flash chip was ready before performing any more actions, its extreme overkill but might as well leave it there. Overall, pretty standard stuff….
