Add two larger WINBOND chips
|
Comment: I then did an Erase so the CopyFromSD sketch could work - and it did! Though it failed before I manually added the SerialFlash.eraseAll() - would have been nice to detect that was needed. Then after adding the Flash JEDEC ID to detect it noted 'Failed' since it needed to be erased. ListFIles works - but that is three sketches I needed to edit to SPI1 with alt MISO and CS pins, and then grief for not being formatted and then not empty. Simple single purpose sketches are nice - but SerialFlash is very opaque without running multiple sketches and even that leaves room for wonder. Of course 'CopyFrom???' has variants to a single sketch couldn't include all ... but getting started wasn't 'easy' COOL NOTE: the read speed test on this chip over SPI1 gives: 5127.17 kbytes/sec
