Hi, I mostly use the SDK 7.2 or SDK 10 and S110 7.1 or 8.0
since I have multiple custom boards that uses revision 2 and 3 chips.
My custom board I'm about to use has...
I want get an interrupt from the ADC after every sample (oversampled by 4, so burst is enabled). This works fine with EasyDMA, but I want to be able to not use the EasyDMA...
Is there some documentation somewhere to explain how these work?
I kinda understand but in app_timer, why use a software interrupt of the same priority as the RTC interrupt...
In my project, the nrf51422 chip will be hosted on a board with another CPU. I need to be able to flash the firmware through the SWD interface, controlled by the host CPU...
Hello,
I have a running system powered by ARM Cortex-M3 (LPC1343 MCU) and I want to add bluetooth through nRF51822 usb dongle.
I want to send some data from LPC1343...
Hi,
I try to send a string using example code ble_app_uart_pca10028 without input from terminal
