Hello,
I have been working with a NUCLEO-WBA55CG board and the X-NUCLEO-IKS02A1 expansion board. When running my initialization code, the program execution jumps to the error handler. Using a debugger, I've pinpointed the failure to the ISM330DHCX_Set_Mem_Bank function. The function returns an error status, which triggers my error handling routine. My initial approach was to replicate the project setup described in DataLogTerminal project . This led directly to the failure at ISM330DHCX_Set_Mem_Bank. I have compared my initialization code against the reference implementation in Board Extension IKS02A1 ISM330DHCX_0_Probe function and they appear to be identical.
My Questions:
- Is there a known compatibility issue for using ISM330DHCX with the NUCLEO-WBA55CG board?
- Could this failure point to a I2C communication problem or a timing issue? How can I fix it?
- Any recommended procedure for initializing I2C or this sensor?
Here is the code that I added:
/* USER CODE BEGIN Includes */
#include "ism330dhcx.h"
#include "stm32wbaxx_nucleo_bus.h"
/* USER CODE END Includes */
/* USER CODE BEGIN 2 */
MX_MEMS_Init();
/* USER CODE END 2 */
/* USER CODE BEGIN 4 */
static void MX_MEMS_Init(void){
ISM330DHCX_IO_t io_ctx;
io_ctx.Address = ISM330DHCX_I2C_BUS;
io_ctx.BusType = ISM330DHCX_I2C_ADD_H;
io_ctx.Init = BSP_I2C1_Init;
io_ctx.DeInit = BSP_I2C1_DeInit;
io_ctx.ReadReg = BSP_I2C1_ReadReg;
io_ctx.WriteReg = BSP_I2C1_WriteReg;
io_ctx.GetTick = BSP_GetTick;
io_ctx.Delay = HAL_Delay;
int32_t ret = 0;
ISM330DHCX_Object_t imu_sensor;
ret = ISM330DHCX_RegisterBusIO(&imu_sensor, &io_ctx);
if (ret != ISM330DHCX_OK){
Error_Handler();
}
ret = ISM330DHCX_Set_Mem_Bank(&imu_sensor, ISM330DHCX_USER_BANK);
if (ret != ISM330DHCX_OK){
Error_Handler();
}
uint8_t id;
ret = ISM330DHCX_ReadID(&imu_sensor, &id);
if (ret != ISM330DHCX_OK){
Error_Handler();
}
if (id != ISM330DHCX_ID){
Error_Handler();
}
ISM330DHCX_AxesRaw_t axes_raw;
ISM330DHCX_Init(&imu_sensor);
ISM330DHCX_ACC_SetOutputDataRate(&imu_sensor, 26.0f);
ISM330DHCX_ACC_SetFullScale(&imu_sensor, ISM330DHCX_16g);
ISM330DHCX_ACC_GetAxesRaw(&imu_sensor, &axes_raw);
ISM330DHCX_GYRO_SetOutputDataRate(&imu_sensor, 26.0f);
ISM330DHCX_GYRO_SetFullScale(&imu_sensor, ISM330DHCX_4000dps);
ISM330DHCX_GYRO_GetAxesRaw(&imu_sensor, &axes_raw);
ISM330DHCX_ACC_Enable(&imu_sensor);
ISM330DHCX_GYRO_Enable(&imu_sensor);
}

Steps to Reproduce:
- Create a new STM32 project in STM32CubeIDE.
- In the Board Selector, choose NUCLEO-WBA55CG and initialize the project with default peripheral settings.
- Navigate to "Connectivity" and enable I2C1. Set the SCL and SDA pins to PB1 and PB2 respectively.
- Change I2C speed mode to Fast Mode. Other settings leave unchanged.
- Navigate to "System Core" RCC. and select HSE and LSE to crystal/ceramic resonator
- Navigate to "Computing" and enable CRC.
- Navigate to "Trace and Debug" Debug and select Serial Wire.
- Navigate to "Timers" RTC and activate Clock Source and Calendar
- Navigate to "Middleware" X-CUBE-MEM1 and activate AccGyr ISM330DHCX
Environment:
- STM32CubeIDE: 1.19.0
- STM32Cube MCU Pack for STM32WBA series: 1.7.0
- X-CUBE-MEMS1: 11.3.0
- Windows 10
