ID do dispositivo SPI

Nuttx auto-atribui 0x40000 como o ID do dispositivo SPI para exibição ST7789. (Veja isso)

Atribuímos o outro dispositivo SPI Ids nós mesmos.

O ID do dispositivo -1 é uma queda para capturar todos os dispositivos SPI que não correspondem aos IDs do dispositivo. Isso também funciona para configurações simples de SPI, onde o ID do dispositivo não é necessário.

Trocar miso / mosi

De acordo com o Manual de Referência BL602 (Tabela 3.1 "Descrição do Pino", página 26) ...

  • GPIO 13 é mosi

  • Gpio 0 é miso

Mas, devido a um BL602 SPI Quirk, precisamos trocar Miso e Mosi para obter esse comportamento. É por isso que a coluna "Swap miso / mosi" está marcada "sim" para transceptor SX1262 e flash spi.

ST7789 O controlador de exibição está conectado de maneira diferente ...

  • ST7789 recebe dados SPI no GPIO 0

  • ST7789 Pino de dados / comando está conectado no GPIO 13

    (Alta para dados ST7789, comandos baixos para ST7789)

A direção dos dados do SPI é invertida para ST7789. É por isso que a coluna "Swap miso / mosi" está marcada "não" para o ST7789 Display Controller.

Tabela de dispositivos SPI

Representamos a tabela de dispositivos SPI acima em Nuttx como uma matriz plana INT ...

Selecionar / desmarcar o dispositivo SPI

O driver BL602 Nuttx SPI procura a tabela de dispositivos SPI para 1ind, trocar o miso e os pinos Mosi 2️⃣ Vire os pinos de seleção do chip. É assim que selecionamos e desmaremos cada dispositivo 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 é chamado após travar o barramento SPI.

Comando / dados SPI

O Nuttx RTOS usa o miso como o pino de dados / comando st7789 ... mas o ST7789 está conectado "para trás" na pilha de pininhas BL604! Usamos o MOSI como o pino de dados / comando ST7789.

Veja como virar o pino de dados / comando st7789, dependendo da troca de 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 ;
    }

O que renderiza a tela de demonstração LVGL no ST7789 corretamente!

Chip SX1262 Selecione

Existe uma condição de corrida em potencial se usarmos o driver SX1262 simultaneamente com o driver ST7789 ...

  • Durante a transmissão do LORA, o driver SX1262 chama ioctl() para flip sx1262 chip selecionar para baixo

    (Veja isso)

  • O driver SX1262 chama o driver de teste SPI /dev/spitest0 , que bloqueia ( SPI_LOCK ) e seleciona ( SPI_SELECT ) o barramento SPI (com ID do dispositivo SPI 0)

    (Veja isso)

  • Observe que as chamadas para ioctl() e SPI_LOCK / SPI_SELECT não são atômicas

  • Se o driver ST7789 estiver ativo entre as chamadas para ioctl() e SPI_LOCK / SPI_SELECT , o chip SX1262 SELECT e o chip ST7789 Select serão invertidos para baixo

  • Isso pode transmitir lixo para SX1262

Para resolver esse problema, registraremos um novo driver de teste SPI /dev/spitest1 com ID do dispositivo SPI 1.

O driver Lora acessará /dev/spitest1 , que SPI_LOCK e SPI_SELECT o barramento SPI (com ID do dispositivo SPI 1).

Como o ID do dispositivo SPI é 1, SPI_SELECT girará o chip SX1262 Selecionar para baixo.

SX1262 LORA Transceptor

Teste Lora

Para testar o Lora no PinEmio Stack, edite sx1262_test_main.c em ... 

 apps/examples/sx1262_test/sx1262_test_main.c

E atualize os parâmetros da Lora ...

  • "Parâmetros Lora"

Teste Lorawan

Lorawan funciona bem no ônibus SPI compartilhado Yay! A pilha PinEnio se conecta ao gateway de Lorawan (Chirpstack) e envia pacotes de dados.

(O sensor de temperatura interno no ADC também funciona bem)

Lembre -se de desativar todas as informações do registro de informações porque afeta os temporizadores de Lorawan.

Veja como definimos os parâmetros de Lorawan ...
