I would like to have some help about using the PN5180 chip with a Renesas RX231 family (R5F52318ADFP)
I use 2 demoboard:
- PN5180 : PNEV5180B 2.2
- Renesas : YR0K505231S000BE
On the PN5180 board, I removed all connections between the LPC1769 and the PN5180 for the SPI(MOSI, MISO, SCK, SSEL, BUSY, PN_RST and PN_IRQ).
I have integrated the NxpNFCRdLib to my program on the Renesas Chip but it doesn't work.
This is my SPI configuration: 2Mbps, CPOL=0, CPHA=0.
The SPI configuration is correct because when I strap MOSI to MISO, I can read the value that I sent.
So I tried to read a register of the PN5180 without using the library.
I write on the register 0x00(32 bits) the value 0x0000AA55 for test.
On the oscilloscope I can see the MOSI frame.
But when I read this register (in debug mode) I received only 3 bytes instead of 4 and the 3 bytes are all 0x00.
Could someone help me please?
Thanks in advance.
