I attempted to use https://github.com/Protocentral/protocentral_max30001_zephyr_driver to build my project. However, I am still encountering some issues.
1.In the overlay file, I used the following:
Only spi nodes accepted in /soc/spi@4002f000/.
/soc/spi@4002f000/max30001@0/
max30001: max30001@0 {
compatible = "maxim,max30001";
reg = <0>;
spi-max-frequency = <DT_FREQ_M(1)>;
int-gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
label = "MAX30001";
rtor-enabled;
ecg-enabled;
bioz-enabled;
ecg-gain = <3>;
ecg-invert;
};
2.In the prj.conf file, I included the following configurations:
CONFIG_SENSOR=y CONFIG_SENSOR_MAX30001=y CONFIG_GPIO=y CONFIG_SPI=y CONFIG_USE_SEGGER_RTT=y CONFIG_RTT_CONSOLE=y CONFIG_LOG=y CONFIG_LOG_BACKEND_RTT=y
3.My
main file is as follows:
#include <zephyr/kernel.h>
#include <zephyr/device.h>
#include <zephyr/devicetree.h>
#include <zephyr/drivers/sensor.h>
void main(void)
{
const struct device *sensor = device_get_binding(DT_LABEL(DT_INST(0, maxim_max30001)));
if (!device_is_ready(sensor))
{
printk("Device not ready.\n");
}
else
{
printk("Device is ready.\n");
}
if (!sensor)
{
printk("No device found.\n");
return;
}
printk("Device found: %s\n", sensor->name);
/* Additional code to read data from the sensor */
}
But I keep getting "Device not ready."
