Hi! I am currently doing my project on BLE beacons. I am using nordic's nrf51822 and waveshare ble400. I am using a blackmagic probe instead of jlink to program it using Arduino IDE. I want to use sandeep's ... (more)
i would like to connect two Redbearlabs Nano v2 just with eachother. The central one connects just to the peripheral, but the peripheral is still open for every device. So i want to use direct advertising and give the ... (more)
I need 3.3V on my Arduino connector, I need to use the Arduino shield. I am measuring 3V on VDD line. According user guide, if I cut SB38 , VDD will be disconnected, I assume this means that I will ... (more)
I am using various sensors to build a wireless sensor network. There are libraries for sensors that are provided by developers such as from adafruit or sparkfun. I have been using them in arduino with adafruit's nRF52 Bluefruit to ... (more)
What is the easiest way to use Arduino libraries into nrf52 projects in Keil on C? Arduino has a lot minus : bad ide, not support debug mode, not optimize code size. But it has one huge plus, you can use ... (more)
I'm in the process of migrating from arduino to SES IDE(For more practicality and functionality now what I'm trying to achieve is saving time by not having to rewrite all arduino libraries I'm currently using ... (more)
I've recently properly started programming my nrf52832 DK with segger embeded studio playing a little with the debuging tool break points modifing example ect...
and I came across this function NRF_LOG_INFO(); which I guess is for outputing the ... (more)
I would like to start off by saying I am not a very experienced programmer and I only have base knowledge of Java and Android Studio. Furthermore, I have no experience in Bluetooth communication or BLE. I've done a ... (more)
I currently have 2 redbear nrf51822 nano. I want to connect the UART of the nrf51822 to my arduino uno/nano but i dont know how i should do this. I tried looking for a solution but cant seem to ... (more)
Hello im trying to create a single master connected to multiple slave to make synchronous movement for my robotic arm project but im not entirely sure which Bluetooth to consider getting. I want it to be operated in arduino and ... (more)
Hi, I bought an Arduino PrimoCore card and I read that you need to buy the Alicepad card. I can not find it on the net. But was it put on the market? Thank you.
Hi, I try to mount some I2C devices at Arduino Primo but I can not get any results. I tried an I2C LCD that did not return any error but did not display any text. When I scan I2C devices ... (more)
I had purchased the Red Bear Labs "Micro" board to develop code using their MK20 USB Dongle and Arduino.
If I "hack" the programming cable to emulate the "Micro" daughter board to match the pins used on the PC2006 Beacon ... (more)
I've already tried before using ADXL345 using nRF51822 using mbed compiler this is the link.. https://os.mbed.com/users/asyrofi/cod...
but that program can't get ADXL345 data, just UART nRF51. I've tried using nrf51822 too ... (more)
I'm develope some sensor with arduino primo, which use nrf52832 as a primary mcu. I want to measure battery voltage level,and i find some example like: https://devzone.nordicsemi.com/questi...
but i confused with which SDK ... (more)
I had some erratic results when I hook these devices via SPI, using a level shifter (e.g. TXB0104) to protect the nRF52. When I look at the schematic for the nRF52-DK I see that there is no level ... (more)
I am not sure if it is the right place. I was looking for WiFi: 802.11 b/g/n 2.4 GHz support in Arduino UNO and stumble into Arduino primo, which is developed in cooperation with Nordic ... (more)
using the sample code at
i am able to use nrf24l01 to communicate raspberry pi with arduino, but the problem is the timing. I found it takes > 20 ms to send a very simple string ... (more)
do I have a chance to activate oversample for an ADC by using Arduine IDE?
Best regards, Christian
I was pointed to st7565LCD.c for this question before, but SDK 13 does not seem to have that example. It would be really helpful if I can get spi_read() and spi_write() functions as welll. thanks.
I wanted to know if it was possible to connect the nRF52840 to an arduino so I can program it (nR52840) with Arduino's IDE.
Using the nrf52 DK, I was trying for hours to setup Segger IDE on a mac, and the software doesn't feel good to me, its not clear where is your code, it has too many libraries, it feels cumbersome ... (more)
I am in the process of porting arduino library VL53LX01 to the nrf51822 using nrf_drv_twi functions. I will use this with S130 and thinking of using blocking mode.
I initialized without giving interrupt handler and hope it will run on ... (more)
i want to communicate nrf52dk with arduino over spi.i want use nrf52dk as a master and ardunio as a slave.kindly refer me some example or code or any thing which s helpful . thanks
I'm just wondering if you can provide me with files/links that have EAGLE files for Schematics and alink for Arduino Primo.
Am beginner of nRF51822, please suggest programming tool and tutorial links.
Hi everyone on the community.
I've been struggling trying to upload the hex file created by arduino using redbear nrf arduino fork on a NRF51822 -v2 board that is being sold at ebay.
the hex file size is around ... (more)
hi I'm porting Arduino code which has calls to ShiftIn() to read a byte from a GPIO Pin and bitWrite() to write a bit into a byte variable at a particular position. Below is example arduino code:
