I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC[0] is 1000, and CC[1] is 8000.
I use compare[0] to toggle gpio18 by PPI. I also want to use compare[1] to...
Hi,

Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...

In nRF5 SDK 12.1.0 a bug was fixed in nrf_drv_wdt_init(). Watchdog timeout could not be larger than 131 seconds because of (x * 32768) multiplication before. This bug is again...
In the spec it says that the typical ramp up time is 140us (or 40us in fast mode). But there is no details on maximum or minimum. What is the true tolerance on this value...
We are building a simple project, let 51822 connect the mobile, once per second. We found that the Tx power of 51822 is getting weaker and weaker (view the voltage over a...
I have a nrf51 dongle and would like to use PWM on 3 pins.
Managed to get it working on pins 15 and 16, but somehow pins from 17 to 20 just don't work.
For example: I set...
Hi,
I have two nrf52840 boards and I am using the ble_app_att_mtu_throughput test app. The tests seem to be working OK, but I am not getting the throughput I was expecting...
When performing flash operations, i.e. via FDS or FSTORAGE, etc. - will GPIOTE events be captured and 'queued' until the CPU is no longer halted?
Said another way:

Hello everyone,
I tried to connect with nrf51 with andriod 5.x .On connection indication the Master (android ) shows the following values of connection parameter (taken...
Hi guys
Given that the sample capacitor is 2.5pF max, the quoted source resistances that are supposed to match the settable sample times seem to be extremely conservative...
