Marvin_G WROTE:zhenning WROTE:Marvin_G WROTE:do i really need to put the "" thing when writing the command to the device?
Yes you need that. What are you trying to do first? I believe there is one row of commands rather than just 0xF5?
if you can go to this link and download it's manual you might can help me because i don't really know how the command works. http://www.cytron.com.my/viewProduct.ph ... er%20(UART)
yes theres a row of command such as " 0xF50xF5000000xF5 " this command is for deleting all the data inside the DSP processor of the fingerprint reader.
