I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi, I am working on a project where I want to make one nrf51288 chip as central hub and connect that to a android phone and other salve nrf51288 .
idea similar to this: ...
Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
I've modified the ble_app_uart example by adding GPIOTE so that the transmitter sends a character to the receiver when a GPIO pin is toggled. This part is working well.
...
Hi,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
I want to build nrftoolbox app in android studio. I downloaded the zip file from the github website and also the required dfu library. I unzipped both the files in a folder...
Hello Nordic!
I am using an Android phone and a nRF51822, and I'm performing BLE speed tests.
For these two devices the theoretical maximum is given by 4 * 20 / 0.0075 ...
So I have a remote, a central, and it's connected to my peripheral.
The remote is based on the multilink example.
SDK V11.
I want to press a button on my central and...
Hi, i'm wondering if it's possible to make a GPIO pin trigger different tasks when it is externally driven from low to high, and high to low.
I'm trying to stop an RTC...
I would like to NRF51822 bluetooth test.
It has NRF51822 eval-kit 2EA.
1EA is a Central (dongle role), 1EA want to test the bluetooth interlock with Peripheral.
What should...
I hope this isn't a duplicate of another question. I searched on sd_power_system_off and didn't see anything exactly like this.
I'm creating a new project, based on ble_app_template...
I have the 51822 chips, and want to establish a network with large data volume, I use the S130 now, but the effect is not ideal, so I want try the BLE4.2. Do we have the SoftDevice...
Hi,
For the past few weeks I've been trying to make a small device that would simulate a mouse with Arduino and MPU6050 accelerator + gyroscope sensor. I wanted the device...
created a new BSP PCA10001 from PCA10028 and replaced the CFLAGS += _DBOARD_PCA10001 for uart example in peripheral folder using sdk 10.
Migrated simple_uart example &...
Hello,
I wish to communicate with the chip via SPI NRF51822.
The NRF chip is configured as a slave. Based on the SPi_slave_example code, I can't set to 1 the semaphore...
I configured my system to sleep after inactivity time.
nrf_gpio_cfg_sense_input(WAKE_UP, NRF_GPIO_PIN_NOPULL, NRF_GPIO_PIN_SENSE_HIGH);
err_code = sd_power_system_off...
NRF51822 most time is in sleep mode.
Each 5 seconds it wakes up to make ADC measurements.
But adc_event_handler force only once, but I want to see it every 5 seconds.
