Hi,
I am sending data from Android phone in every 200 ms to nRF8001. But sometimes I found there is a 50 ms or 100 ms delay. It looks like nRF8001 spending some time in...
Hello,
I'm starting a new nRF51 project on mbed for a custom board. I wish to know what is the "cleanest" way to define pinout (what file to edit) ?
Thank you
I have enabled data ready interrupt bit and also enabled the fifo bit and also enabled gyro_fifo and accel_fifo bits in mpu6050 so that when data ready interrupt occurs the...

I'm loading the code using the J-link into my board or the evaluation board (PCA10007) that I have, the code runs perfect...
Hi all, I met a problem with measuring lithium battery voltage. I used 1Mohm and 250Kohm divided voltage, and used the internal VBG voltage as reference, and used ADC0 as...
I'm using a nRF51844
I'm writing my own ADC reading routines because I can't find any examples, but I know how to code so that's not a problem. I just want to confirm something...
Hi,
does a code example or app-note exists that describes how to configure the SPI peripheral to use an ISR to transmit data to a SPI slave?
Thank you in advance!
Dear
