Hi everyone I am currently trying to connect some simple sensors using the I2C interface.
Currently I am working with an nRF5340 and nRFC 1.6.1 SDK
I loaded one of the samples using the FXAS21002 module.
Everything works fine on i2c1 when using the dedicated pins i.e.P1.02 <34> and P1.05 <35>.
For testing I tried using some other pins let's say P1.14 <46> and P1.15 <47> and this is the overlay I am using
&i2c1 {
compatible = "nordic,nrf-twim";
status = "okay";
scl-pin = <46>; //p1.14
sda-pin = <47>; //p1.15
// sda-pin = <35>;
// scl-pin = <34>;
clock-frequency = <I2C_BITRATE_STANDARD>;
fxas21002@21 {
compatible = "nxp,fxas21002";
status = "okay";
reg = <0x21>;
label = "FXAS21002";
};
};
and for the project file
CONFIG_STDOUT_CONSOLE=y CONFIG_LOG=y CONFIG_I2C=y #CONFIG_NRFX_TWIM1=y CONFIG_SENSOR=y CONFIG_FXAS21002=y CONFIG_SENSOR_LOG_LEVEL_DBG=y #CONFIG_FXAS21002_TRIGGER_OWN_THREAD=y CONFIG_CBPRINTF_FP_SUPPORT=y CONFIG_I2C_NRFX=y
Is it generally possible to use other gpios for I2C? Reading around the answered question it certainly seems that way.
When I use the default pins from the sample everything works fine, also tried a BME280 sensor, no issues at all.
According to other answers the overlay should do the trick to change/declare the proper pins to be used.
AM I missing something in the settings?
