Hello,
My team and I are trying to decide how to power the nrf51822. We will be using a 3.7V lithium ion battery as our power source.
I saw in another post that it is...
I am planning to use the LPCOMP in conjunction with an external reference. I would like to just use a voltage divider to create the external reference.
Are there any impedance...
I recently received a nrf51822 mbed board.
I went with the mbed board over the EK because I figured it was more 'open', without realizing exactly what mbed was. I played...
I use the SPI slave function on 51422. When I send a byte(0x31) to 51422 SPI slave from master, 51422 will back a byte (0xAA - DEF byte) to master. Why?
I send 0x31 every...
Many Bluetooth library features are not yet available and so I would like to use a standard tool chain to compile sample programs and my own programs to run on the mkit.
