可以測試SPI通信winhout外部模塊

[英]Is possible to test SPI communication winhout external module

問題描述

我有一個非常簡單的問題，我想......我正在使用兩個 SPI 通信（一個類 SPI 和第二個 int SPI）在 SAMD21 板上編程，我認為 int SPI 無法正常工作。 如果我連接一些傳感器，它不會在串行監視器上打印任何內容。 我很確定，我的代碼沒問題，但也許會有一些錯誤......

所以我需要知道，是否有某種方法可以測試將外部設備連接到電路板的 SPI winhout。 請不要討厭代碼太長，我使用的 SPI 傳感器的代碼標有“//SPI”。

PS：對不起，我刪除了 SMUART 和 MICS6814 的測量和校准功能，只使用了 30 000 個字符。 完整代碼在這里： https://mega.nz/file/2QxG0ayZ#4UpEU17ogXnm2NK22zAowlDDRrXzksPzzs05zbuq23o

大多數 SPI 接口都可以置於“環回”模式，這使得代碼可以輕松檢查活動以驗證發送/接收的數據

關於：

if (error != 0)
{
    isGpsConnected = false;
}

// begin communication with gps
gps.begin();

如果沒有連接 GPS，則不應嘗試與 GPS 通信。 建議：

if (error != 0)
{
    isGpsConnected = false;
    return;
}

else
{
    // begin communication with gps
    gps.begin();
}
