DigitalIO is a HTML library typically used in Internet of Things (IoT), Arduino applications. DigitalIO has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

restructured for future use of arduino library manager. pinio and i2c classes are only supported on avr. for detailed documentation see the html files. the functions in this library do not clear pwm mode for pins. clearing pwm mode for each call has a high overhead and does not address the fact that pins can be in other special modes such as serial, i2c, or spi. the digitalpin class provides very fast in-line functions. digitalpin is a template base class and pin numbers must be specified at compile time. for 328 pins and low address mega pins, read() and write() execute in two cycles or 125 ns for a 16 mhz cpu. fast static functions similar to the

            Python script module not found on rerun of script
            Asked 2022-Feb-01 at 20:37

            I am running a python script on RaspberryPi 4, and today when I ran the script again, it showed me the error ModuleNotFoundError: No module named 'adafruit_ssd1306' although I ran this same script yesterday about 10 times, it ran perfectly without any errors. I did not change anything in the script, not even its location. I tried force reinstalling the library, running the script from another location, rebooting the pi, running it as sudo but none of them worked either. By using pip3 freeze it shows that the package is installed and trying to install the package again says that the requirement is already satisfied.

            I am trying to use passing a choice of pins to the raspberry py when creating channels and want to change only the .P(value) when calling the method. For if I call the class in another class I currently have to import all libraries again with the way it is now. Below is code.

            ANSWER

            Answered 2021-Aug-14 at 09:07

            I think you can define constants P0 to P7 in your module that defines createChannel, and then other files can import those constants from that module instead of getting them from MCP directly. Also, you can just specify a channel with an integer from 0 to 7.

            I found some online documentation for adafruit_mcp3xxx.mcp3008. I think it means the channel names like MCP.P0 and MCP.P1 are really just integer values like 0 and 1, respectively.

            The ADC chips’ input pins (AKA “channels”) are aliased in this library as integer variables whose names start with “P” (eg MCP3008.P0 is channel 0 on the MCP3008 chip). Each module that contains a driver class for a particular ADC chip has these aliases predefined accordingly. This is done for code readability and prevention of erroneous SPI commands.

            You can make channel names available to users of your createChannel method by defining constants P0, P1 and so forth in the module that defines createChannel.

            Stopping a function based on a value
            Asked 2021-Apr-14 at 01:26

            I am running a python script on a raspberry-pi.

            Essentially, I would like a camera to take a picture every 5 seconds, but only if I have set a boolean to true, which gets toggled on a physical button.

            initially I set it to true, and then in my while(true) loop, I want to check to see if the variable is set to true, and if so, start taking pictures every 5 seconds. The issue is if I use something like time time.sleep(5), it essentially freezes everything, including the check. Combine that with the fact that I am using debouncing for the button, it then becomes impossible for me to actually toggle the script since I would have to press it exactly after the 5s wait time, right for the value check... I've been searching around and I think the likely solution would have to include threading, but I can't wrap my head around it. One kind of workaround I thought of would be to look at the system time and if the seconds is a multiple of 5, then take picture (all within the main loop). This seems a bit sketchy.

            Check digit code after keypress using a keypad in Python
            Asked 2021-Apr-07 at 12:15

            My goal is checkin if a digit code e.g.1234# is wrong or correct (using a keypad like this)

            So my plan was to enumerate() items inside the list given by keypress, extract each value from the list using element index and finally validate the code. The problem is in the keypress function of the library because it always gives a list where all the values have the same index (0)

            How can I achieve this? Maybe using list comprehension?

            keypress is a one-item list, with key's value. If you try to enumerate over it, you will get only one item, on index 0.

            If you want to get all code, you need to store clicked keys, e.g.:

            in adafruit_hid.mouse you have to Send USB HID reports before you use the LEFT_BUTTON so you have to put a variable at the start of your code like this

            LEFT_BUTTON = 1 for the LEFT MOUSE BUTTON

            RIGHT_BUTTON = 2 for the RIGHT MOUSE BUTTON

            MIDDLE_BUTTON = 4 for the MIDDLE MOUSE BUTTON

            I've been trying to solve this problem for hours, to no avail. So, I've been trying to run an OLED screen for showing the weather, time, etc. I wrote the script with a while loop so it can run virtually forever. However, I also want to be able to start the script with a GPIO pull-up, and end it with yet another high GPIO pin. Using the on-off script to start the OLED script works flawlessly with variables, yet the script seems to be blind to the variable changes my "Off-GPIO" tries to introduce. Here's my code:

            Alright, after some tinkering, I found a solution! I discovered that RPi.GPIO has a simple way to check a pin's state with input.GPIO(channel). [This teached me a valuable lesson: Always read the documentation] I just did some simple if and while statements to solve my issue. This way has its caveats on its own, but it does what I want it to do.
