Hi,
I'm having trouble with how to begin debugging a hard fault error in my code. When I run the debugger, it always ends in the HardFault_Handler in arm_startup_nrf51.s...
I am developing a project by employing nRF51822 and my code is based on ble_app_uart. I met an issue that if there is no device connects to nRF51800 in 3 minutes, the program...
The nrf51 ARM Cortex-M0 processors, according to the documentation, are "code compatible with Cortex-M3". Does this mean they implement LDREX/STREX instructions for atomic...
Hei,
We would be using nrf52 chip in a very miniature device that should have both BLE and NFC capability. NFC is needed for just as a tag. Thus, nrf52 is a good option....
I moved from SDK 7 to SDK 9. I'm using timers with SDK7
