I am getting error messages in VSCode I cannot deduct from the code (a simple UDP server test). The code is compiling and running fine. Errors are as follows:
My platformio.ini is:
[env:az-delivery-devkit-v4]
platform = espressif32
board = az-delivery-devkit-v4
framework = arduino
lib_deps =
Ethernet=https://github.com/arduino-libraries/Ethernet.git
monitor_speed = 115200
monitor_dtr = 0
monitor_rts = 0
lib_ldf_mode = deep+
monitor_filters = esp32_exception_decoder
build_flags = -DMY_SSID=\"hidden\" -DMY_PASS=\"hidden_as_well\"
The code is:
#include <Arduino.h>
#define UDPMODE 2
#if UDPMODE == 1
#include <WiFi.h>
#include <WiFiUdp.h>
#elif UDPMODE == 2
#include <Ethernet.h>
#include <EthernetUdp.h>
#endif

const char * ssid = MY_SSID;

Serial.print("Failed to configure Ethernet using DHCP\n");
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.print("Ethernet shield was not found. Sorry, can't run without hardware. :(\n");
} else {
if (Ethernet.linkStatus() == LinkOFF) {
Serial.print("Ethernet cable is not connected.\n");
}
}
while (1) {} // Do nothing any more
}
// We seem to have a connection to the router
lIP = Ethernet.localIP();
Serial.printf("My IP address: %u.%u.%u.%u\n", lIP[0], lIP[1], lIP[2], lIP[3]);
#endif
//This initializes udp and transfer buffer
udp.begin(udpPort);
}
void loop(){
//processing incoming packet, must be called before reading the buffer
uint32_t bts = udp.parsePacket();
//receive response from server, it will be HELLO WORLD
if (bts) {
char *buffer = new char[bts + 1];
if(udp.read(buffer, bts) > 0){
buffer[bts] = 0;
Serial.print(buffer);
}
delete[] buffer;
}
}
I suppose the static code check is missing to scan platformio.ini for additional defines and include paths, but why?
