I used analog IIC write MPU6050. Again after power download programs, mpu6050 can run up there ACK response. But the debug will not run. Simulation IIC because no...
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.

IN COMP of 52832, I find that a current source around the COMP form a OSC with a cap. I want to know what is the use of this OSC. And can the current source be disabled if...
I have a few characteristics under a service, and I'm trying to store the value if any of these characteristics is written to. However I run into an issue where if I enable...
Hi !
There is one thing I don't understand with the led included on the NRF51-DK board.
According to this thread ( devzone.nordicsemi.com/.../ and the datasheet it seems...
I want to take saadc samples for one second,every 5 seconds,the rest of the time the mcu is in system on sleep mode with rtc1 on.Eery 5 second there is an rtc event and the...
As the datasheet showing
The GPIOTE input mode consumpt upto 22uA ,it is inconceivable.I want use NRF51822 to design a ultra low power consumption production ,and use...
