UART0, UART1 and I2C0 utilization and Initialization

Yes, I tried to initializae the I2C0 peripheral using

void init_i2c_master()
{
dev_i2c = device_get_binding("I2C_0");
if (dev_i2c == NULL) {
printk("Failed to get I2C0 binding\n");
return;
}
}

after disable of UART1 using  

void disable_uart1(){
NRF_UARTE0->TASKS_STOPTX = 1;
NRF_UARTE0->TASKS_STOPRX = 1;
}

but, I2C initilaize fail, when run Debug .. though build and Compile is successful.

Hi

Could you post the error message you receive?

To get more debug information, set the following configurations in prj.conf:

CONFIG_RESET_ON_FATAL_ERROR=n
CONFIG_LOG=y
CONFIG_THREAD_NAME=y

Hello, I tried after adding the configurations in prj.conf, but I2C0 binding is not successful.

Please, test the following Code:

Please post the error message you get.

Hi, the build and Compile is successful, but whrn Debug, then Get_Device_binding(I2C0) fails. Plesae, test the program at your end, sent in just previous reply one earlier.

Hi

I ran your sample, and I see your issue.

But I just found the nrfx peripheral resource sharing example.

It explains your problem and show a way to fix it.
