Hi Sir / Madam,
I need your help in configuring Pass Through which can be use in 2 way communication. Millions of thanks.
I would like to configure pass through and use the SRAM mapping feature of NTAG I2C 1K. With reference to NT3H1101_1201.pdf, Page 52/65, Section 11.3.1 SRAM buffer mapping, it says that " In Pass-through mode, the SRAM is mirrored to pages F0h to FFh sector 0 for the NTAG I²C 1k " . Does this means that after I configure Pass Through (session register, NC_REG byte, bit 6 - PTHRU_ON_OFF = 1b) , what I wrote to SRAM (Block address 0xF8 to 0xFB) from I2C interface will be automatically mirrored to location, starting at 0xF0 ? And the data in block 0xF0 can be retrieve by another NFC device, for example device B ? Also, device B can write to this location (block address 0xF0) , and then data in this location can be access by I2C interface, and then to Microcontroller ?
I have configured Pass Through and then write to SRAM, then I use another device to scan the NFC of this device and retrieve its data. From my IDE, I read through all 255 pages of data, the portion at page 0xF0 (from RF perspective) is all 0x00, which is not correct. Please help.
Thank you for your advice.
