Hi,
I'm trying to get the FTM examples from the STSW-ST25R-LIB to work on a ST25R3916.
I am using the following hardware:
-Mikroe NFC 4 Click Board with a ST25R3916
-STEVAL-25R3916B (I only use the reader/antenna board STEVAL-D25R3916B without the Mcu board)
-Nucleo L476RG microcontroller board (as it is the one used in the sample projects from the library)
On the software side I am using the FTM examples from the X-NUCLEO-NFC06A1 (for 3916 on Mikroe board) and X-NUCLEO-NFC08A1 (for 3916B on Steval board) folders in the lib. The programs seem to be identical, only the global definition for the HW/reader selection is different.
When I use the NFC08A1 program with the Steval, the reader works fine. But when I use the NFC06A1 example with the Mikroe board it doesn't work. When I try to read the chip ID in the initialisation process, it always reads zero. I have checked this interaction with a logic analyser in both examples and have attached the screenshots. I have tried both SW examples on both boards (I changed the reader/HW define in the compiler/preprocessor options so naturally, it should work). Both examples work on the Steval and both do not work on the Mikroe.
I have connected some jumper (supply, SPI and IRQ) cables directly to the Nucleo board and I only change them on the reader side when testing with the two boards so all the tests i did should be quite identical in HW and SW except from the used Board/Reader.
Any help would be greatly appreciated.
