how complete is the library?
The library is almost complete, I tested it succesfully on one of my SST25VF016B chips. I was able to read single and continuous byte, write single byte and erase the whole chip. Plus I can write and read the status registry (writing is necessary at startup to remove area protection) and read the chip vendor info. Missing parts are: 32K and 64K block erase and continuous writing (word). I will use it embedded in a 5" TFT touchscreen (it has to be soldered) I have ordered some days ago. Once the tft has arrived I will finish the library.
I do not know Micron 5PQs but I will check the datasheets. I do not think it will be difficult to adapt the library if it is a serial Flash via SPI. Of course I have to find a couple of chips to experiment on.
please, remember to put a link to your library here
