1hz is only available on some watches. The f5, f5s, f5x, 935, and Q5, but if you support a bunch of different watches, you can easily have it on some and not others. 1hz happens by way of a new onPartialUpdate() for watch faces. onUpdate() is just like it was in the past, and when you are allowed to do a 1hz update, onPartialUpdated() is called.

Nov 29, 2018 · I would like to set a pwm output on my UNO to run at a 1 Hz frequency and then, by analogWrite, set it at 10% or 90% dutycycle. Can that be done? If so, how do I do it? The background is my need to waist some current in a low power consuming project to keep the powering powerbank away from cutting off. In a test project using millis() the frequency of 1Hz and 10% dutycycle does the trick. Now ...

Sep 24, 2018 · Hello, i am learning how to use I2C, speccially with ds3231 for starting, there are a lot of libraries to make ds3231 work but i want to learn from scratch, i´ve been readiing some pdf files and for my first attempt i tried to enable SQW function at 1hz here is the code. #include <Wire.h> int ds3231_address = 0x68; //ds3231 address void setup()

Aug 21, 2020 · Hi, I can find lots of "hits" for MAX PWM Frequency, but I want Sub-Hz values (0.1 - 0.5Hz). Using this commonly found technique: int PWM_FREQUENCY = 1; // this variable is used to define the time period int PWM_CHANNEL = 0; // this variable is used to select the channel number int PWM_RESOUTION = 8; // this will define the resolution of the signal which is 8 in this case int GPIOPIN =2 ...

Jun 10, 2020 · Hello, I want to generate square wave and be able to change frequency using potentiometer between around 24750Hz-25250Hz with step = 1Hz. I tried to calculate it and change frequency by adjusting prescaler and ICR1 but it changes in really random way now. Do you know what i can change in my code to make it work? 🙂 float start=323.23; float x=0; float y=0; int value=0; float voltage = 0; int ...

Jan 5, 2013 · Hello everyone! I have been trying to use the Arduino Uno to create square pulses at the following frequencies, 10Hz, 5Hz, 1Hz, .5Hz, and .12Hz using PWM. I’ve been using Timer1 in CTC mode with a 1024 (1562Hz) prescaler. The problem is that as I lower the frequency, the waveforms I see on the oscilloscope looks less and less like a square wave. 10Hz, 5Hz, and even 1Hz produces a square wave ...

Apr 11, 2010 · Hi, I've just ordered an arduino board for a new project I'm working on. I need a PWM output running at about 1Hz to drive a SSR... I've been browsing the documentation and it seems the lowest PWM you can achieve is about 30Hz, by changing a timer register. Are there any tricks to make it go any lower? Edit: also, obviously, I'll be wanting to change the duty cycle. Any info on doing this ...

Sep 21, 2013 · Like said in the subject what would be the easiest way to make an adjustable square wave(50% duty cycle) that can be adjusted from 1hz(doesn&#39;t have to be that low but it&#39;d be nice) to 1Mhz(doesn&#39;t have to be that high ma&hellip;

Oct 3, 2011 · Hallo, ich versuch verzweifelt den Timer0 im 1hz/1s Takt eine Interrupt-Routine aufrufen zu lassen, jedoch läut es immer viel zu schnell.
