Guidance for returning result from read
Toshiba01 opened this issue · comments
Hi,
I need a little bit of guidance:
wire.read(length, function(err, res) { // result contains a buffer of bytes });
taking in consideration this function, how can I return result value to be used in the code outside of this function?
something like: var returnedValue = wire.read(length, function(err, res){ return res})
Thank you!
I'd recommend using Promises if you can't use the callback block.
