Ultralight C – configurationMemoryAccess help

[Chelo Cava]

Hello, we are trying to solve an issue with access permission we cant find too much documentation about the method configurationMemoryAccess

public void configurationMemoryAccess(int pageNumber,

                                      byte configuration)

In javadoc it says configuration byte:
The restriction: 0x00 = read and write access restricted, 0x01 = write access restricted

We need to free again for writing and reading freely. what byte configuration should we put? and where is that info? Thanks!


Our code is:

//lock

ultralightC.configurationMemoryAccess(4, (byte) 0x00);

//unlock

ultralightC.configurationMemoryAccess(4, (byte) 0x0E);

Hi Chelo,

Taplinx is a layer for the Ultralight C commands and if you are in doubt, refer to the Ultralight C datasheet. The memory access is controlled with the bytes AUTH0 and AUTH1 and explained on page 18 of the datasheet.

You will find the datasheet here:
