1 year ago いきなりそのままコンパイルは流石に無理だった。
- PIO の Library 設定から M5Core2.h と LovyanGFX.hpp を作業用 Project にインストールした。特に M5Core2.h は既に別プロジェクトで使用していたから、新規Project ごとにインストールが必要なのかと気づくのに少し時間がかかった
最初に試したソースコード
#define LGFX_AUTODETECT // 自動認識
#include <M5Core2.h>
#include <LovyanGFX.hpp>
#include <WiFi.h>
#include <FS.h>
#include <SPIFFS.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>
#include <AsyncJson.h>
#include <ArduinoJson.h>
#include "base64.hpp"
const char *wifi_ssid = "dronebird";
const char *wifi_password = "dronebird";
#define HTTP_PORT 80
#define FORMAT_SPIFFS_IF_FAILED true
#define BUFFER_SIZE 30 * 1024
unsigned char buffer[BUFFER_SIZE];
AsyncWebServer server(HTTP_PORT);
static LGFX lcd;
void wifi_connect(const char *ssid, const char *password);
void notFound(AsyncWebServerRequest *request){
if (request->method() == HTTP_OPTIONS){
request->send(200);
}else{
request->send(404);
}
}
void setup() {
Serial.begin(9600);
SPIFFS.begin(FORMAT_SPIFFS_IF_FAILED);
wifi_connect(wifi_ssid, wifi_password);
lcd.init();
server.on("/get", HTTP_GET, [](AsyncWebServerRequest *request) {
AsyncWebParameter *p = request->getParam("download");
if( p != NULL )
Serial.println(p->value());
request->send(200, "text/plain", "Hello, world");
});
AsyncCallbackJsonWebHandler *handler = new AsyncCallbackJsonWebHandler("/post", [](AsyncWebServerRequest *request, JsonVariant &json) {
JsonObject jsonObj = json.as<JsonObject>();
int p1 = jsonObj["p1"] | -1;
const char *p_param = jsonObj["param"];
if( p_param != NULL ){
if (decode_base64_length((unsigned char *)p_param) <= sizeof(buffer) ){
int length = decode_base64((unsigned char *)p_param, buffer);
lcd.drawJpg(buffer, length);
}
}
// request->send(200, "application/json", "{}");
AsyncJsonResponse *response = new AsyncJsonResponse();
JsonObject root = response->getRoot();
root["p1"] = p1;
root["message"] = "Hello World";
response->setLength();
request->send(response);
});
server.addHandler(handler);
server.on("/image", HTTP_GET, [](AsyncWebServerRequest *request) {
request->send(SPIFFS, "/www/img/test.jpg", "image/jpeg");
});
server.serveStatic("/", SPIFFS, "/www/").setDefaultFile("index.html");
server.onNotFound(notFound);
DefaultHeaders::Instance().addHeader("Access-Control-Allow-Origin", "*");
DefaultHeaders::Instance().addHeader("Access-Control-Allow-Headers", "*");
server.begin();
}
void loop() {
// put your main code here, to run repeatedly:
}
void wifi_connect(const char *ssid, const char *password){
Serial.println("");
Serial.print("WiFi Connenting");
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{
Serial.print(".");
delay(1000);
}
Serial.println("");
Serial.print("Connected : ");
Serial.println(WiFi.localIP());
}その後にコンパイルしてもやはりエラー
