问题描述
我正在尝试从本地服务器获取数据并将其打印在P10点矩阵Led上。 首先，我尝试从服务器和程序代码中获取数据，效果很好。 然后，我尝试另一个程序，并将任何纹理成功写入P10。 之后，我尝试合并程序并运行脚本。 这是代码。

WiFiClient client;
HTTPClient http;
Serial.print("[HTTP] begin...\n");
if (http.begin(client,"http://XX.XX.XX.XX/XXX")) { // HTTP
Serial.print("[HTTP] GET...\n");
// start connection and send HTTP header
int httpCode = http.GET();
// httpCode will be negative on error
if (httpCode > 0) {
// HTTP header has been send and Server response header has been handled
Serial.printf("[HTTP] GET... code: %d\n",httpCode);
// file found at server
if (httpCode == HTTP_CODE_OK || httpCode == HTTP_CODE_MOVED_PERMANENTLY) {
String payload = http.getString();
Serial.println(payload);

} else {

}
http.end();
} else {
Serial.printf("[HTTP} Unable to connect\n");
}
}
delay(10000);
}
运行代码后，程序将运行并将数据成功写入P10 led矩阵10-20秒。但是几秒钟后，它崩溃了。 这是crach代码和异常解码器代码。

我意识到，当我删除dmd.begin();时，程序不会崩溃，但不会写入led矩阵。
有人可以帮助我吗？谢谢。
