MEGA with Adafruit WINC1500 Shield
I’m having trouble getting the Adafruit WINC1500 shield to work with the MEGA. There are posts that indicate how it should be connected, etc but I can’t it to show that the shield is present. And I’ve read that the MEGA isn’t compatible with this shield. So I’m a bit frustrated and confused. Has anyone successfully connected these two together and if so, what’s the secret. I want to use an external antenna for my project so the Adafruit seemed like a good choice. Thanks for your insight.
Debug UNO R3 with Arduino IDE 2.3.10
Hi all, I trying to use the debugger as described by Felias-Fogg (see https://github.com/felias-fogg/dw-link/releases/tag/v6.1.1). I build it on a breadboard, and It works but I see some things I can’t explain. I created 3 global variables (uint8_t tellerVal = 0; uint8_t ledPin = 11; int delayTime1 = 25;) at the begin of the sketch. I put them also in the watch window of the debugger to see how the change when I step through the program. The variable tellerVal changes by every step and is ok. But if I look in the “Variables window”, I see only the variable ledPin. What am I doing wrong, according to me they should be all visible in the “Gobal window”. Sketch code: /* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of your board at: https://docs.arduino.cc/hardware/ modified 8 May 2014 by Scott Fitzgerald modified 2 Sep 2016 by Arturo Guadalupi modified 8 Sep 2016 by Colby Newman This example code is in the public domain. https://docs.arduino.cc/built-in-examples/basics/Blink/ */ uint8_t tellerVal = 0; uint8_t ledPin = 11; int delayTime1 = 25; void stop(); // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(ledPin, OUTPUT); pinMode(12, OUTPUT); Serial.begin(9600); Serial.println("Setup done."); } // the loop function runs over and over again forever void loop() { digitalWrite(ledPin, HIGH); // change state of the LED by setting the pin to the HIGH voltage level delay(delayTime1); // wait for a second digitalWrite(ledPin, LOW); // change state of the LED by setting the pin to the LOW voltage level delay(delayTime1); // wait for a second tellerVal++; if (tellerVal == 50) { stop(); } } void stop() { delay(2000); tellerVal = 0; }
