Bus SPI bersama

Menurut skema tumpukan Pinedio ...

  • Pinedio Stack Skema (2021-09-15)

  • Pinedio Stack Baseboard Skema (2021-09-27)

Bus SPI dibagikan oleh ...

  • Pengontrol tampilan ST7789

  • SEMTECH SX1262 LORA Transceiver

  • Spi Flash

Berikut adalah nomor GPIO BL604 untuk bus SPI bersama ...

Fungsi Gpio
SPI MOSI 13
SPI Miso 0
SPI SCK 11
SPI CS (tidak digunakan) 8

(Sumber)

Untuk mencegah crosstalk, kami memilih setiap perangkat SPI dengan membalik pin pilih chip dari tinggi ke rendah ...

Perangkat SPI ID Perangkat SWAP Miso/Mosi Chip pilih
Tampilan ST7789 0x40000 TIDAK 20
SX1262 Transceiver 1 Ya 15
Spi Flash 2 Ya 14
(Perangkat default) -1 Ya 8 (tidak digunakan)

(Sumber)

ID Perangkat SPI

NUTTX Auto-Signs 0x40000 sebagai ID perangkat SPI untuk layar ST7789. (Lihat ini)

Kami menugaskan ID perangkat SPI lainnya sendiri.

ID perangkat -1 dimaksudkan sebagai fallthrough untuk menangkap semua perangkat SPI yang tidak cocok dengan ID perangkat. Ini juga berfungsi untuk pengaturan SPI sederhana di mana ID perangkat tidak diperlukan.

Tukar miso / mosi

Menurut Manual Referensi BL602 (Tabel 3.1 "Deskripsi Pin", halaman 26) ...

  • GPIO 13 adalah mosi

  • Gpio 0 adalah miso

Tetapi karena kekhasan BL602 SPI kita perlu bertukar miso dan mosi untuk mendapatkan perilaku ini. Itu sebabnya kolom "swap miso / mosi" ditandai "ya" untuk transceiver sx1262 dan spi flash.

Pengontrol tampilan ST7789 ditransfer secara berbeda ...

  • ST7789 menerima data SPI di GPIO 0

  • ST7789 Pin Data / Perintah terhubung pada GPIO 13

    (Tinggi untuk data ST7789, rendah untuk perintah ST7789)

Arah data SPI dibalik untuk ST7789. Itu sebabnya kolom "Swap Miso / Mosi" ditandai "no" untuk pengontrol tampilan ST7789.

Tabel Perangkat SPI

Kami mewakili tabel perangkat SPI di atas di NUTTX sebagai array int datar ...

Perangkat SPI ID Perangkat SWAP Miso/Mosi Chip pilih
Tampilan ST7789 0x40000 0 20
SX1262 Transceiver 1 1 15
Spi Flash 2 1 14
(Perangkat default) -1 1 8

Pilih / Batalkan Pilihan Perangkat SPI

Driver BL602 NUTTX SPI Mencari Tabel Perangkat SPI ke 1️⃣ Swap Miso dan Mosi Pins 2️⃣ Balikkan pin pilih chip. Beginilah cara kami memilih dan membatalkan pilihan setiap perangkat SPI ... 

 //  Enable/disable the SPI chip select
static void bl602_spi_select ( struct spi_dev_s * dev , uint32_t devid ,
                             bool selected )
{
  const int32_t * spidev ;

  spiinfo ( "devid: %lu, CS: %sn" , devid , selected ? "select" : "free" );

  /* get device from SPI Device Table */

  spidev = bl602_spi_get_device ( devid );
  DEBUGASSERT ( spidev != NULL );

  /* swap MISO and MOSI if needed */

  if ( selected )
    {
      bl602_swap_spi_0_mosi_with_miso ( spidev [ SWAP_COL ]);
    }

  /* set Chip Select */

  bl602_gpiowrite ( spidev [ CS_COL ], ! selected );

#ifdef CONFIG_SPI_CMDDATA
  /* revert MISO and MOSI from GPIO Pins to SPI Pins */

  if (! selected )
    {
      bl602_configgpio ( BOARD_SPI_MISO );
      bl602_configgpio ( BOARD_SPI_MOSI );
    }
#endif
}

bl602_spi_select dipanggil setelah mengunci bus SPI.

Perintah / Data SPI

NUTTX RTOS menggunakan miso sebagai pin data / perintah ST7789 ... tetapi ST7789 terhubung dengan "mundur" di Pinedio Stack Bl604! Kami menggunakan MOSI sebagai pin data / perintah ST7789 sebagai gantinya.

Begini cara kami membalik pin data / perintah ST7789 tergantung pada swap miso / mosi ... 

 #ifdef CONFIG_SPI_CMDDATA
static int bl602_spi_cmddata ( struct spi_dev_s * dev ,
                              uint32_t devid , bool cmd )
{
  spiinfo ( "devid: %" PRIu32 " CMD: %sn" , devid , cmd ? "command" :
          "data" );

  if ( devid == SPIDEV_DISPLAY ( 0 ))
    {
      const int32_t * spidev ;
      gpio_pinset_t dc ;
      gpio_pinset_t gpio ;
      int ret ;

      /* get device from SPI Device Table */

      spidev = bl602_spi_get_device ( devid );
      DEBUGASSERT ( spidev != NULL );

      /* if MISO/MOSI are swapped, DC is MISO, else MOSI */

      dc = spidev [ SWAP_COL ] ? BOARD_SPI_MISO : BOARD_SPI_MOSI ;

      /* reconfigure DC from SPI Pin to GPIO Pin */

      gpio = ( dc & GPIO_PIN_MASK )
             | GPIO_OUTPUT | GPIO_PULLUP | GPIO_FUNC_SWGPIO ;
      ret = bl602_configgpio ( gpio );
      if ( ret < 0 )
        {
          spierr ( "Failed to configure MISO as GPIOn" );
          DEBUGPANIC ();

          return ret ;
        }

      /* set DC to high (data) or low (command) */

      bl602_gpiowrite ( gpio , ! cmd );

      return OK ;
    }

  spierr ( "SPI cmddata not supportedn" );
  DEBUGPANIC ();

  return - ENODEV ;
}
#endif

Batalkan pilihan semua perangkat SPI

Di NUTTX Startup, kami membatalkan pilihan semua perangkat SPI ... dengan membalik chip mereka pilih pin tinggi ... 

 static void bl602_spi_init ( struct spi_dev_s * dev )
{
  struct bl602_spi_priv_s * priv = ( struct bl602_spi_priv_s * ) dev ;
  const struct bl602_spi_config_s * config = priv -> config ;

SX1262 Chip Pilih

Ada kondisi balapan potensial jika kita menggunakan pengemudi SX1262 secara bersamaan dengan pengemudi ST7789 ...

  • Selama transmisi LORA, SX1262 Driver Panggilan ioctl() untuk membalikkan chip SX1262 yang dipilih menjadi rendah

    (Lihat ini)

  • SX1262 Driver Panggilan SPI Test Driver /dev/spitest0 , yang mengunci ( SPI_LOCK ) dan memilih ( SPI_SELECT ) bus SPI (dengan ID Perangkat SPI 0)

    (Lihat ini)

  • Perhatikan bahwa panggilan ke ioctl() dan SPI_LOCK / SPI_SELECT bukan atom

  • Jika driver ST7789 aktif antara panggilan ke ioctl() dan SPI_LOCK / SPI_SELECT , keduanya chip SX1262 SELECT dan chip ST7789 Select akan dibalik ke rendah

  • Ini mungkin mengirimkan sampah ke SX1262

Untuk mengatasi masalah ini, kami akan mendaftarkan driver tes SPI baru /dev/spitest1 dengan ID perangkat SPI 1.

Driver Lora kemudian akan mengakses /dev/spitest1 , yang akan SPI_LOCK dan SPI_SELECT bus SPI (dengan ID perangkat SPI 1).

Karena ID Perangkat SPI adalah 1, SPI_SELECT akan membalik chip SX1262 yang dipilih menjadi rendah.

Tampilan ST7789

Uji Lora

Untuk menguji lora di stack pinedio, edit sx1262_test_main.c di ... 

 apps/examples/sx1262_test/sx1262_test_main.c

Dan perbarui parameter lora ...

  • "Parameter Lora"

Uji Lorawan

Lorawan bekerja dengan baik di Bus SPI bersama Yay! Pinedio Stack terhubung ke Lorawan Gateway (ChirpStack) dan mengirim paket data.

(Sensor suhu internal pada ADC juga bekerja dengan baik)

Ingatlah untuk menonaktifkan semua penebangan info karena memengaruhi timer Lorawan.

Begini cara kami mengatur parameter Lorawan ...
