arduino led stock ticker

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) We get only one timer to work. #include. Ticker is os_timer Each Ticker calls one function. //=====================================================================. //===================================================================== I plan on using pegboard and about 250 bi-color (red-green) LEDs to make a marquee that is 5 x 50 (not 100% set on the dimensions). Example sketches for the new Arduino IDE for ESP8266. timer1_write(600000); //120000 us Serial.println(“”); pinMode(interruptPin, INPUT_PULLUP); A scrolling text display, using 294 LEDs to simulate a stock exchange ticker.

A function may be attached to a ticker and detached from the ticker. */ There are two timers in ESP8266 Timer0 and Timer1, one timer is used by its WiFi functions. Flashing keeps failing at 12% with timed out waiting, Trying to sniff "MAC" around me , different Probe request?>. Total: “); The internal resolution is now micros(), this works with intervals up to 70 minutes. when it crashes copy and paste the "BackTrace " into the decoder (under tools) and it will show where your code crashed. You can edit this in the line that says: ser = serial.Serial('COM',9600) Next, open up your Arduino IDE to copy-paste your code into the editor.

How to remove sections of .debug_frame, .debug_info , etc. //===================================================================== Serial.println(numberOfInterrupts); To avoid crash issues I recommend use of Ticker instead of Timer. the" if" and "digitalRead" will use a few clock cycles and act as a good bebouncer, // ISR routine for button digitalWrite(LED,! rudy . Upload the program and see LED starts blinking at every 0.5 seconds. if( interruptCounter < 0 ) interruptCounter = 0; 2 — debounce the pin, a capacitor on the pin will also help about .1 to 1Uf I wanted to count a number of interrupts on pin D3 in a certain period of time. }, ALSO install the "ESP Exception Decoder" For longer intervals you can change the resolution to millis().
