i2c read block is to be fixed

[lhdangerous]

According to johnny-5 document, There should be 'how many bytes' for the 3rd argument of 'i2cReadOnce()' function. But your i2c extension doesn't have this and acts unexpected way. Can you update this please?

Hi August @lhdangerous

I will check this (especially in the words used) but 3 initial comments (I don't have much time now)

• The first slot of the "i2c read" block is really the "how many bytes" argument.
• The "register" argument is missing... and I haven't needed in any case (checking Arduino libraries). In fact, if you read carefully i2cReadOnce docs, there are 4 arguments (address, register, bytesToRead, callback) but when there are 3, the register is bypassed and the seconc is the "bytesToRead".
• Anyway, you can make your own workaround. You can see (editing the blocks) there are JS blocks. And you can do whatever you need and make your own block with all 4 arguments.
