Questions about the Nor51822 BLE and PWM?

[creator]

How do you do

Now use the Nordic \ nRF5_SDK_12 2.0 _f012efa \ examples \ ble_peripheral \ ble_app_uart this plus Nordic \ nRF5_SDK_12 2.0 _f012efa \ examples \ peripheral \ pwm_library this routine. 1. Only PWM operation, use the bluetooth connection will be disconnected after sending data.I ask, is there any way to solve this?

There is a problem is PWM Pwm1_cfg. Pin_polarity [0] = APP_PWM_POLARITY_ACTIVE_LOW; Pwm1_cfg. Pin_polarity [1] = APP_PWM_POLARITY_ACTIVE_HIGH; The polarity, in contrast, only 50% duty cycle is also good, if only 20% duty cycle appeared two road waveform is not the same, now want to two road waveform, and the 20% duty cycle is two way as the waveform. image description The first two high pulse is in the intermediate position of the first low pulse all the way as shown in figure

Hi,

1. Yes, there is a way to solve this. You are probably running into the error-handler, see this post on how to debug. You can also post your code here, and I can take a look at it.

2. I don’t think the PWM library support this phase delay functionality out-of-the-box, but it should be possible to do using some TIMERS, PPI and GPIOTE. See e.g. this post.
