Currently developing a system based around the NRF9160 running Zephyr. My application is threaded and i would like to run the thread_analyzer. I got this working...
Hello,
I want to hide the BLE(RF signals) completely soon after updating the configuration in my application and whenever I need to update the config I should be able to...
Hi, I'm reading an ADC channel connected to large capacitors. I do the read when charging is off so no ripple. The caps are large (super-caps) so hold well enough to show...
Hey. If the device is repeatedly flashed without turning off its power (it does not matter if I program it through SES or nRFgo), it may start to malfunction or slow down...
Hello
I would like to use three PWM to output multiple sounds with one buzzer.
First of all, I am testing using two PWM. There is no problem using only one PWM, but there...
Hi, I'm currently using TAIYO YUDEN's EYSLCNZWW (nRF52810) and We are developing a device like a pulse oximeter.
I would like to change SAADC_SAMPLE_RATE from 400ms to 100ms...
Hi, after using the nRF SDK examples with SES for some time now, I decided to go with a project from scratch but for some strange reason the directory where I keep the nRF...
