Do I have any restriction with HW Pinout Peripheral when using s130?

[Daniel T. Lee]

if I use softdevice 130 Enabled, then do I have any restriction with using all of the pinout of NRF51xxx?

Or if I use Nrf-51 DK, Do I have any restriction with nrf 51xxx's full pinout functionality?

To Make it Easy, I've read at some document that, If I use S130, I will have some restriction with some peripheral's such as Timer 0 like this. In this point of view, Do I have any restriction with NRF51xxx's Pinout Such as I cannot use GPIOTE Pin 32,33 (example) or PWM Pin 32,33 Cause S130 Use those Pins. ?

Actually I've found lot's of Nordic's document, But I can't find restricted pin's when I use Softdevice 130.

• Do I have restriction with only software Peripheral (such as Timer)? No restriction with Hardware Pins?( ex UART, I2C, PWM, GPIOTE, SPI?)

Hi,

The softdevice blocks and restricts access to some hardware peripherals. You can see which peripherals are affected in the softdevice documentation. As you can see, GPIO P0 is open, meaning you can use the GPIOs as you want when the softdevice is enabled.

Best regards,

Actually, There are no mention about PWM. HOW About it?

DO I can Use PWMs as I want when softdevice is enabled?

[Jørgen Holmefjord]

There is no hardware PWM peripheral on the nRF51 series. The PWM library use timers, GPIOTE and PPI to generate PWM singals. If you make sure you don't use TIMER0 peripheral and PPI channels blocked by the softdevice, it should be no problem.
