Motoo Tanaka / Mbed 2 deprecated testSPI_IS25LQ032B

a test program for my SPI_IS25LQ032B library. please set local-echo on for the terminal program.

Dependencies:   SPI_IS25LQ032B mbed vt100

At start up the program show the list of available commands

起動すると、使用出来るコマンドの一覧が表示されます。

/media/uploads/Rhyme/000_is25_startup.jpg

To see the contents of the first 256 bytes of memory, type

dump 0x00

最初の256バイトを表示させるのには dump 0x00 と入力してください。

/media/uploads/Rhyme/001_is25_dump_0x00.jpg

Let's write a value 0xA5 to address 0x10

write 0x10 0xA5

Then see the result with

dump 0x00

先ず、アドレス 0x10 に 0xA5 を書き込みます。 write 0x10 0xA5

その結果を再度 dump 0x00 コマンドで表示させると

/media/uploads/Rhyme/002_is25_write_read_dump.jpg

To erase the entire memory, use command

cer

メモリ全体を初期化するのには　cer コマンドを使用してください。
