I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC[0] is 1000, and CC[1] is 8000.
I use compare[0] to toggle gpio18 by PPI. I also want to use compare[1] to...
Hi,
I use two evk board to connected and test the uart serialization sample(ble_s110_serialization), one is ble_app_hrs and one is ble_app_connectivity. But I have one...
I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
Are there any examples for audio recognition using Nordic Edge AI Lab audio (aka Neuton) ?
I am ready to start creating my model, but was wondering if there were examples...
I run the system_off example without the system actually going off, by removing all the calls to start the system_off worker. Instead of going to off, I let the system enter...
Hello
I played with the mcuboot_recovery_entry bare metal dfu sample. I noticed that if I sign an application image with an invalid key (invalid on purpose), the firmware...
I have been reviewing the antenna section in the datasheet of the BLE audio SoC nRF5340. The datasheet mentions a single-ended antenna output (on-chip balun). Could you explain...
Hi,
When the firmware is run in debug mode (J-Link connected), the system always works correctly. BLE initializes properly, and all sensors function as expected.
When...
Hello, everyone. I am an undergraduate student majoring in Mechanical Engineering in South Korea.
I am currently working on a research project to develop a PPG sensor using...
Hi,
(I'm assuming that the main() function of an application is actually executed as a thread.) I can't find any clear documentation that describes how a thread can suspend...
Hello team,
I am trying to interface the AT45DB641E flash with the nrf54l15 on a custom board. I am using the SPI00 instance.
Below is the configuration I set in .overlay...
Hi Nordic team,
We are working on a design that includes more than 50 peripheral node devices, each capturing sensor data and sending it to a single central receiver. I...
Hi,
I'd like to know how to tune the internal capacitance from the 32MHz crystal.
Specifically, I refered to section 4.12.1.1 Using internal capacitors in the nRF5340...
I am using the nrf52840 in QFAA package, and the external DMIC example receives audio data through the PDM interface. I noticed that the official documentation mentions support...
Hello,
We have been testing/validating sQSPI on nRF54L15.
We tested the sQSPI on two versions of our nRF54L15DK (0.9.2 and 0.9.3).
We are using this sample app: https...
Hello. I have one question.
When configuring RAM with the nRF5 SDK + SoftDevice, if I get the following error: APP_RAM_START=0x20006000 --------------------------------...
Hi,
I'm trying to program the nRF52840 Dongle (PCA10059, 2.1.1, 2023.26). I modified the Bluetooth: Central UART sample to use USB instead of UART and built it for the dongle...
I need to use one IO port of the nrf52832. This IO can not only detect the ECG signal but also achieve system off wake-up. The ECG signal is a PWM signal with a duty cycle...
