3 Creative ideas with Arduino

I need to count the frequency of pulses on one of the ESP 32 inputs without using interrupts. There is no arduino-esp32 HAL for the pcnt peripheral, so you will need to use the esp-idf functions.

Linked pull requests.Each pulse counter unit has a bit signed counter register and two channels that can be configured to either increment or decrement the counter. Each channel has a signal input that accepts signal edges to be detected, as well as a control input that can be used to enable or disable the signal input.

The inputs have optional filters that can be used to discard unwanted glitches in the signal. Operating the Counter - provides information on control functions to pause, measure and clear the counter. Filtering Pulses - describes options to filtering pulses and the counter control signals.

Using Interrupts - presents how to trigger interrupts on specific states of the counter. This applies to counter operation with or without a filer. The PCNT unit features filters on each of the pulse and control inputs, adding the option to ignore short glitches in the signals.

The event happens on the pulse counter reaching specific values:. Note Each Pulse counter unit has five watch point events that share the same interrupt. All enabled events share the same interrupt one interrupt per pulse counter unit. The handler will be attached to the same CPU core that this function is running on.

If non-NULL, a handle for the interrupt will be returned here. Any pulses lasting shorter than this will be ignored when the filter is enabled.

This limit is smaller compared to a global PCNT interrupt handler due to the additional level of indirection. Note We can manage different interrupt service for each unit. Note Configuration covers two actions, one for high, and one for low level on the control input. Note Configuration covers two actions, one for positive, and one for negative edge on the pulse input.

Everything in IDF is available here. Most of the things I saw as peripherals and network are already implemented in Arduino language. I am trying to use PCNT in this program.

I am not getting any counts when i read the counter value. I am using a pulse generator to input pulses on pins 27 and Any thoughts? I have the same result No reaction for pulses Honestly, I played with the code very long time and read a lot of on the internet discussions. Now, the code is part of huge project, I can't remove it form it, don't know, what exactly must be preset or whatever.

Ultimately this is opening up a range of opportunities for the print industry in offering pack and product personalization, customization and premiumization. Brands want to add value to their packs to create differentiation. As a result of these trends, and confirmed by members and partners, EFIA is seeing a keen focus on stand out graphic design utilizing new tactile coatings and ink effects, as well as the use of complementary flexo and digital print systems to deliver short runs of customized packs.

Pack designs are being tested more regularly with sophisticated variable data to connect to digital marketing campaigns enticing the consumer. Further growth in retail ready or shelf ready packaging is also helping to deliver the in store stand out as well. The message is clear: the industry is not standing still. The pace of change is accelerating and the opportunities for industry growth are significant. LED ink curing is set to grow substantially next year.

Digital print has made product multi-versioning and label multi-language versioning easy and quick. While over 20 percent of brand owners we surveyed said they do not currently source digitally-labels, they nevertheless say they want their label converters to have digital capability on their production floor.

European brand owners will also continue to demand higher quality at lower prices from their packaging suppliers, and are increasingly looking to the developing economies of, for example, Hungary, the Czech Republic, Poland and Slovakia as viable label sourcing channels.

What is more, our most recent Radar research confirms interestingly that more than 70 percent of them claim that they will not be migrating from self-adhesive labelling technology to another format over the next 12 months.

Sustainability will be a headline topic in the agenda of the entire supply chain. Waste management will be the prime concern of Finat and its sister associations around the world in 2017.

If the European economy avoids a slowdown in 2017 there may be some catching up and consequently a good 2017 for labels and packaging. If sterling remains under pressure, the UK will suffer from cost-push inflation and possibly a recession. However, UK exports will be more competitive abroad, which could be good news, e.

Within labels globally, we expect IML to be a key growth area and expect the leading players will roll out their expertise to new territories, building on existing multinational relationships with FMCGs which are penetrating new markets with premium products.

Jennifer Dochstader, managing director, LPC2016 was a pivotal year for the label printing industry. During Labelexpo Americas, we witnessed the unveiling of a new generation of entry-level digital production presses that allow converters to move into the digital print space at viable price points. We also saw companies showcasing digital inkjet retrofit technology, turning conventional flexo presses into hybrid print systems.

Looking forward, the digitization of the industry will continue. This trend will persist, however not only at the converter level. We speak with brand owners on both sides of the Atlantic every day and in the research work LPC does with industry associations, we are seeing a small number of consumer packaged goods companies and contract packagers across North America and Europe buy digital presses to vertically integrate some or all of their label printing requirements.

Digital press manufacturers foresee this trend growing in 2017. For label converters, in an increasingly competitive landscape, the core challenge is to constantly find new ways to add value to the products and services they offer.
