Hi,
I am writing a firmware for one of my custom boards which use GPIOTE to detect interrupt for 3 GPIOs inputs (P0.03, P0.06 and P0.09, both with internal pull-ups) and...
Hello,
I'm trying to write my ADC samples over spi on a sd card (Using SAADC like in the sdk 12 example with PPI and using fatfs like in the example in the sdk).
I open...
I have been using the pc-ble-driver Python bindings to implement a peripheral. I have extended BLEDriver to support sd_ble_gatts_* the functions. I now have a working peripheral...
Hi All,
I am struggling with this question from many days. Does the SPI transmit or receive operation in SPI master code uses DMA? While using SAADC DMA I have specified...
I'm using an app timer to blink an LED while in the bootloader.
Initially I was configuring an app timer when the bootloader started up and never stopped it, assuming the...
After failing in replacing a Cortex M4 for a NRF52832 I'm studying the possibility of using a NRF51822 as a BLE controller, used by my Cortex M4 MCU.
As I saw there is...
Hello
Please tell me about sd_ble_gatts_value_get ().
Before execution, handle is 0x11, but after execution it will be 0x00.
Is this an abnormal thing?
In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
