I recently blogged about Nordic and Hackathons, but didn't include too much information; I knew already there was something coming. And now it is finally published: #HackDublin - Ireland's First Design & Hardware Hackathon. In this comprehensive article you will find videos of the idea pitches, team interviews, final pitches, and some presentation. If you are involved in the maker movement you probably want to see the talk by Mark Hatch, the founder of TechShop.If you click on the image belo...

Today, QuickLogic announced the availability of our TAG-N Wearable Sensor Hub evaluation kit for the Nordic Semi nRF51 DK, Nordic’s all-in-one, multiprotocol development kit for ultra-low power wireless development on the nRF51822 SoC. We’re very excited to be part of the Nordic ecosystem, and just as excited to offer system designers an off-the-shelf, proven sensor hub for immediate integration. System Description:The TAG-N system is a self-contained system. It contains the Quic...

Recently we introduced support for CMSIS-Pack into our nRF51 SDK. The nRF51 SDK is natively supported in the Keil IDE. This means that nRF51 SDK latest version and example software for nRF51 are easily found in the Keil IDE. To do this install the Keil IDE and use the build-in “Pack Installer” (it is important to use Keil 5.12 or later). This tool also informs you of newest released versions of the SDK. It also has a nice browser to look through available examples.Here is a sho...

Hello,We're interested in measuring the precision of our external crystal, but don't have the equipment to measure off the crystal directly without affecting capacitive loading.Some microcontrollers have the ability to drive the clock out a GPIO pin, but I haven't seen anything mentioned for the nRF51822.I've been able to use the RTC tick event to trigger a GPIOTE task to toggle a pin, but this ends up dividing our clock by 2 and possibly introducing further jitter.I'd like to know if there's a ...

I am creating four timers in my application using `app_timer.c`. All timers work except the timer with ID zero never triggers.( means first timer created does not work all timers created after first one works perfectly)I am using `SCHEDULER`for timers and all other things (ble_stack and buttons) APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, true);This is how i created timer err_code = app_timer_create(&m_timer_id, APP_TIMER_MODE_REPEATED, m_timeout_handle...

AN36 refers to the Send Update button on Master Control Panel(to toggle the LED). I can only see a "Write" and "Write Long". Am I doing something wrong, or does AN36 refer to an older version of MCP?...
