how to use hardware spi and i2c on S130 softdevice(nRF51822)??

[simon]

Hello,

I am developing a new product using S130 on nRF51822(QFAC). My product use LCD as spi interface and ADXL345 sensor as i2c interface, also test it, works well without softdevice, but when I upload S130 softdevice it goes to h/w fault.

I searched similar problem in this forum, but I cannot find clear solution. Is it possible use hardware spi and i2c on s130 softdevice concurrently?? Please let me know how to handle this problem.

Yes, you are right. It works now.

I omitted ADXL375_I2C_init() code at main().

twi_init(); ADXL375_I2C_init(&m_twi_adxl_345); //adding this code, the problem is solved.

Thanks,
