STM32 I2 C Проблемы с чипом NF C

Question

Я создал печатную плату с STM32F207ZET6 , и на ней установлена ​​микросхема NXP NF C, подключенная через I2 C. Проблема в том, что я не могу связаться с чипом NF C.

Я проверил соединение I2 C между чипом ARM и NF C. Я проверил, что оба чипа получают правильную мощность.
Я использую stm32cube IDE со stlink-v3. Я настроил контакты I2C1 и написал следующий код:

Что я пробовал

• Я пытался использовать HAL_I2C_IsDeviceReady(), чтобы увидеть, если NF C был подключен. Это возвращает true, но оно также возвращает true для каждого адреса, который я там ввел.
• Я пытался отправлять команды, а также считывать их обратно в буферный массив. Все, что было возвращено, было 0.

    cmds[1] = 0x60;
    cmds[2] = 0x00;
    HAL_I2C_Master_Transmit(&hi2c1, nfc_Adr_w, cmds, 2, HAL_MAX_DELAY);

    HAL_Delay(15);

    HAL_I2C_Master_Transmit(&hi2c1, nfc_Adr_w, cmds, 1, HAL_MAX_DELAY);

    HAL_I2C_Master_Receive(&hi2c1, nfc_Adr_r, buffer, 1, HAL_MAX_DELAY);

Любая помощь будет принята с благодарностью, спасибо.
