Hi is there anyone who knows if you can change the time on how often the health server model send out, the health server model is from lightswitch demo
Hi,
I wanna use nrf51822 as master which has 2 slaves: sdcard (fatfs) and adc
I set SPI_INSTANCE 0
and they don't want to work together, I mean I'd like to write some...
A time T_PINR is specified in the datasheet, as shown in the snippet below.
Does this give me an indication of the pulse width for a pin reset? If so, how do I interpret...
Not really a question, just that I find the comment misleading. In the sdk_config.h example coming with the SDK there is this piece of code:
