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。

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。
