Crawling up the learning curve here, doing my best to solve my own problems, but I'm down to just permuting things on this one and I'm not making much progress and all the examples I can find just seem a little different to what I want to do..
Trying to get an nRF52833 dev kit talking I2C to an eeprom.
Overlay file
&i2c0 {
compatible = "nordic,nrf-twi";
status = "okay";
sda-pin = <26>;
scl-pin = <27>;
clock-frequency = <100000>;
my_eeprom:nRF52833@28 {
status = "okay";
reg = <0x28>;
label = "config_eeprom";
};
};
proj.conf
CONFIG_BT=y CONFIG_BT_DEBUG_LOG=y CONFIG_BT_L2CAP_TX_BUF_COUNT=5 CONFIG_BT_PERIPHERAL=y CONFIG_BT_DEVICE_NAME="Woggle" CONFIG_BT_DEVICE_APPEARANCE=962 CONFIG_HEAP_MEM_POOL_SIZE=2048 CONFIG_I2C=y CONFIG_GPIO=y # This example requires more workqueue stack CONFIG_LOG=y
my code
#define twi0 DT_LABEL(DT_ALIAS(my_eeprom))
voi dmain(void)
{
int err = 0;
LOG_INF("Starting LiftlogDX\n");
//init I2C
const struct device *i2cdev=device_get_binding(twi0);
i2c_configure(i2cdev, I2C_SPEED_SET(I2C_SPEED_STANDARD));
The Error:
DT_N_ALIAS_my_eeprom_P_label" is undefined
I feel close, but it's eluding me..
Tips?
