CO2-Ampel board support

[philippesikora]

Thank your for your great job.

I would like to use WiFiWebServer library on CO2-Ampel board with information as below: SAMD21 + WINC1501B (WiFi101)

/ Needed for WINC1501B (WiFi101) library // --------------------------------------

define WINC1501_RESET_PIN (12u) // reset pin

define WINC1501_WAKE_PIN (11u) // wake pin

define WINC1501_CHIP_EN_PIN (10u) // enable pin

define WINC1501_INTN_PIN (13u) // int pin

define WINC1501_SPI SPI

define WINC1501_SPI_CS_PIN (14u) // cs pin

https://github.com/mariolukas/Watterott-CO2-Ampel-Plus-Firmware https://learn.watterott.com/breakouts/co2-ampel/

I tried the following settings with many compilation errors

include

define USE_WIFI_NINA false

define USE_WIFI101 true

Is it possible to make a slight modification on WiFiWebServer library to support CO2-Ampel board running WiFi101 ? Thank you

Hi @philippesikora

The CO2-Ampel board has been implicitly supported, because it's using SAMD21 and WiFi101 library.

You have to follow these steps

1. Install the CO2-Ampel core by following the instruction in Compile your own traffic light version from the sources
2. Select the board CO2-Ampel from Arduino IDE
3. Compile and upload

This is the compile result as well as the illustration

1. Illustration

2. Compile result =>OK

Thank you for your quick reply. I used AdvancedWebServer example, select the board CO2-Ampel from Arduino IDE, compile (set my ssid[ ] & pass[ ] ) and upload successfully to the board I got the following result on serial monitor:

Starting AdvancedServer on SAMD MKR1000 with WiFi101 using Wifi101 Library WiFiWebServer v1.3.0 Connecting to WPA SSID: sceslaw HTTP server started @ 3003623616

I cannot see my IP address

[khoih-prog]

The very old WiFi101 library uses the medieval way to return IP address in uint32_t, such as

uint32_t localIP();

whereas the modern library returns IPAddress, such as

IPAddress localIP();

The 3003623616 in uint32_t is IPAddress(192, 168, 7, 179) or 192.168.7.179 or B3,07,A8,C0 in HEX

You have to use a cast to convert from uint32_t to IPAddress to modify WiFi.localIP() in the code from

Serial.print(F("HTTP server started @ "));
Serial.println(WiFi.localIP());

to

Serial.print(F("HTTP server started @ "));
Serial.println( (IPAddress) WiFi.localIP());

to print the normal IP = 192.168.7.179
