pinedio stack bl604 apache nuttx rtos的RISC-V板

閱讀文章...

  • “ pinedio stack bl604運行apache nuttx rtos”

Pinedio Stack BL604是Pine64的最新微控制器板，該板基於Bouffalo Lab的BL604 RISC-V + WiFi +藍牙LE SOC。

（現在有一天可用！）

Pinedio堆棧充滿了塞滿的功能...

  • ST7789顏色LCD顯示

    （240 x 240像素）

  • CST816S觸摸面板

    （通過I2C連接）

  • Semtech SX1262 Lora收發器

    （與Lorawan合作）

  • AT6558 GPS / GNSS接收器

  • SGM40561電源管理單元

  • 心率傳感器，加速度計，指南針，振動器

  • SPI Flash，JTAG調試端口，按鈕

  • 2.4 GHz WiFi，藍牙LE

    （感謝BL604）

這使其成為物聯網教育的令人難以置信的小工具！

pinedio堆棧上Apache Nuttx RTOS的源代碼在這裡...

  • lupyuen/uncubator-nuttx（pinedio分支）

  • lupyuen/incubator-nuttx-apps（pinedio分支）

nuttx build for pinedio stack bl604 ...

  • .config

要下載，為Pinedio stack BL604配置和構建NUTTX ... 

mkdir nuttx
cd nuttx
git clone --recursive --branch pinedio https://github.com/lupyuen/incubator-nuttx nuttx
git clone --recursive --branch pinedio https://github.com/lupyuen/incubator-nuttx-apps apps

SPI設備ID

NutTX自動分配0x40000作為ST7789顯示屏的SPI設備ID。 （請參閱此）

我們自己分配了其他SPI設備ID。

設備ID -1是捕獲所有與設備ID不匹配的SPI設備的秋季。這也適用於不需要設備ID的簡單SPI設置。

交換味o / mosi

根據BL602參考手冊（表3.1“ PIN描述”，第26頁）...

  • GPIO 13是Mosi

  • GPIO 0是味o

但是由於BL602 SPI Quirk，我們需要交換MISO和MOSI以獲得這種行為。這就是為什麼SX1262收發器和SPI Flash標記“交換味o / mosi”列的原因。

ST7789顯示控制器的連接不同...

  • ST7789在GPIO 0接收SPI數據0

  • ST7789數據 /命令引腳連接在GPIO 13上

    （用於ST7789數據的高度，ST7789命令低）

SPI數據的方向用於ST7789。這就是為什麼ST7789顯示器控制器標記“交換味o / mosi”列的原因。

SPI設備表

我們表示NutTX中的上述SPI設備表作為平坦的int陣列...

選擇 /取消選擇SPI設備

BL602 NUTTX SPI驅動程序將SPI設備桌抬高到1️⃣交換味o和Mosi Pins2️⃣翻轉芯片選擇銷。這就是我們選擇和取消選擇每個SPI設備的方式... 

 //  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
}

鎖定SPI總線後，將調用bl602_spi_select 。

SPI命令 /數據

NutTX RTO使用MISO作為ST7789數據 /命令引腳...但是ST7789在Pinedio stack BL604上接線“向後”！我們將MOSI改為使用ST7789數據 /命令引腳。

這是我們根據MISO / MOSI交換來翻轉ST7789數據 /命令別針的方式... 

 #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 ;

取消選擇所有SPI設備

在Nuttx啟動時，我們取消了所有SPI設備的選擇...通過翻轉其芯片精選的銷釘高...

SX1262芯片選擇

如果我們與ST7789驅動程序同時使用SX1262驅動程序，則可能會有潛在的比賽條件...

  • 在Lora傳輸期間，SX1262驅動程序調用ioctl() flip SX1262芯片選擇為低

    （請參閱此）

  • sx1262驅動程序調用SPI測試驅動程序/dev/spitest0 ，鎖定（ SPI_LOCK ）並選擇（ SPI_SELECT ）SPI BUS（帶SPI設備ID 0）

    （請參閱此）

  • 請注意，呼叫ioctl()和SPI_LOCK / SPI_SELECT不是原子

  • 如果ST7789驅動程序在對ioctl()和SPI_LOCK / SPI_SELECT調用之間處於活動狀態，則SX1262芯片選擇和ST7789芯片選擇將被翻轉為低

  • 這可能會將垃圾傳輸到SX1262

為了解決此問題，我們將使用SPI設備ID 1註冊新的SPI測試驅動程序/dev/spitest1 。

然後，Lora驅動程序將訪問/dev/spitest1 ，它將SPI_LOCK和SPI_SELECT SPI BUS（帶有SPI設備ID 1）。

由於SPI設備ID為1，因此SPI_SELECT將將SX1262芯片選擇為低。

SX1262 LORA收發器

測試洛拉

要在pinedio堆棧上測試lora，請編輯sx1262_test_main.c at ... 

 apps/examples/sx1262_test/sx1262_test_main.c

並更新Lora參數...

  • “洛拉參數”

測試Lorawan

Lorawan可以在共享的SPI巴士上工作！ Pinedio堆棧連接到Lorawan Gateway（Chirpstack）並發送數據包。

（ADC上的內部溫度傳感器也可以正常運行）

請記住，禁用所有信息記錄，因為它會影響洛萬計時器。

這是我們設置Lorawan參數的方式...

  • “設備EUI，加入EUI和應用程序密鑰”

  • “ Lorawan頻率”
