Hi,
I was creating a struct called ch201_device. So below is the code initialization.
typedef struct ch201_device;
//! Chirp sensor device structure.
typedef struct {
ch_mode_t mode;
uint16_t max_range;
uint16_t static_range;
uint16_t sample_interval;
uint16_t rtc_cal_result;
uint32_t op_frequency;
uint16_t bandwidth;
uint16_t scale_factor;
uint8_t i2c_address;
uint8_t app_i2c_address;
uint16_t i2c_drv_flags;
uint16_t part_number;
int8_t oversample;
uint8_t sensor_connected;
uint8_t io_index;
uint8_t i2c_bus_index;
uint16_t max_samples;
uint16_t num_rx_samples;
uint32_t rtc_cal_pulse_ms;
const char *fw_version_string;
const uint8_t *firmware;
uint8_t *ram_init;
void (*prepare_pulse_timer)(struct ch201_device *dev_ptr);
void (*store_pt_result)(struct ch201_device *dev_ptr);
void (*store_op_freq)(struct ch201_device *dev_ptr);
void (*store_bandwidth)(struct ch201_device *dev_ptr);
void (*store_scalefactor)(struct ch201_device *dev_ptr);
uint8_t (*get_locked_state)(struct ch201_device *dev_ptr);
uint16_t (*get_fw_ram_init_size)(void);
uint16_t (*get_fw_ram_init_addr)(void);
ch_api_funcs_t api_funcs;
} ch201_device;
and in the c code, I create a function for that use a method from ch201_device struct. One of them is ch201_wait_for_lock. Below is the code for that function.
int ch201_wait_for_lock(ch201_device *dev_ptr, uint16_t timeout_ms) {
uint32_t start_time = ch201_timestamp_ms();
int ch_err = !(dev_ptr->sensor_connected);
while (!ch_err && !(dev_ptr->get_locked_state(dev_ptr))) {
nrf_delay_ms(10);
ch_err = ((ch201_timestamp_ms() - start_time) > timeout_ms);
}
return ch_err;
}
and as you can see, there is a get_locked_state(dev_ptr). But when I compile that, it gives me an error message on that method. Below is the error log.
..\..\..\..\..\..\components\libraries\ch201\ch201.c(255): error: #167: argument of type "ch201_device *" is incompatible with parameter of type "struct ch201_device *"
while (!ch_err && !(dev_ptr->get_locked_state(dev_ptr))) {
I have load the library and there is no conflict initialization on it. I also use keil uvision for this. Anybody have solution for this? Thanks.
