Facing an issue while interfacing st nucleo expansion board NFC08A1 with another microcontroller

你好

我正在使用 NFC08A1 Nucleo 扩展板。我正在尝试通过 SPI 将此板与另一个 renesas 微控制器连接。我已经通过 SPI 线、IRQ 和 GND、VCC 上的跳线连接了扩展板。

我正在将 RFAL 堆栈用于 3916B IC。

此时,程序初始化 (demoIni()) 已经完成,进入 demoCycle();我发现 rfalSetAnalogConfig((RFAL_ANALOG_CONFIG_POLL |

RFAL_ANALOG_CONFIG_TECH_NFCV |

RFAL_ANALOG_CONFIG_BITRATE_COMMON |

RFAL_ANALOG_CONFIG_RX) );gNfcDev_tate 应该从 RFAL_NFC_STATE_POLL_TECHDETECT 变为 RFAL_NFC_STATE_LISTEN_TECHDETECT,但它却变成了 RFAL_NFC_STATE_NOTINIT。您能否建议如何解决这个问题。

Hi,

gNfcDev.state is not supposed to return to RFAL_NFC_STATE_NOTINIT except during rfalNfcInitialize which is only called once inside demoIni.

I suspect that gNfcDev.state is getting corrupted. If you microcontroller supports watchpoint feature, I would suggest to set a write watchpoint on gNfcDev.state to try to find what is causing this.

Hi

I am using NFC08A1 Nucleo expansion board. I am trying to connect this board with another renesas microcontroller via SPI. I have connected the expansion board via jumpers on SPI lines, IRQ and GND, VCC.

I am using RFAL stack for 3916B IC.

At this point, the program initialization (demoIni()) has been completed and entered demoCycle(); I found that rfalSetAnalogConfig((RFAL_ANALOG_CONFIG_POLL |

RFAL_ANALOG_CONFIG_TECH_NFCV |

RFAL_ANALOG_CONFIG_BITRATE_COMMON |

RFAL_ANALOG_CONFIG_RX));

gNfcDev.state should change from RFAL_NFC_STATE_POLL_TECHDETECT to RFAL_NFC_STATE_LISTEN_TECHDETECT, but it becomes RFAL_NFC_STATE_NOTINIT. Could you please suggest how to solve this problem.

Thanks in advance
