BMI270 SPI with NRF52

[MESS]

Hello i cant use BMI270 with NRF52. Pleas Help me. Cannt found any thıng. 
here my code.

BMI2_INTF_RETURN_TYPE bmi2_spi_read(uint8_t reg_addr, uint8_t *reg_data, uint32_t len, void *intf_ptr)
{
(void)(intf_ptr);
static uint8_t txarr[500];
uint8_t rxarr[500];
txarr[0] = 0x80 | reg_addr;

nrf_drv_spi_transfer(&spi, &txarr[0], 1, rxarr, len+1 );

for (int i = 0; i < len+1; i++)
{
*(reg_data + i) = rxarr[i+1];
}

return BMI2_INTF_RET_SUCCESS;
}

BMI2_INTF_RETURN_TYPE bmi2_spi_write(uint8_t reg_addr, const uint8_t *reg_data, uint32_t len, void *intf_ptr)
{
(void)(intf_ptr);
volatile static uint8_t txarr[5000];
txarr[0] = reg_addr;
for (uint8_t i = 0; i < len; i++)
{
txarr[i + 1] = *(reg_data + i);
}

nrf_drv_spi_transfer(&spi, &txarr[0], (uint16_t)len + 1 , (void *)0, 0);
return BMI2_INTF_RET_SUCCESS;
}void bmi2_delay_us(uint32_t period, void *intf_ptr)
{
nrf_delay_us(period);
}

Hi Mess, 

I saw your msg in different loop. You got -9 error correct? 

That means when you downloaded config file, there is some issue. 

I assume your read write length is not enough for our default length 46. 

Could you go common.c and change READ_WRITE_LEN value as 8? 

Also, it would be great if you capture and share it to me. 

Thank you.

Hello Minhwan 

do you mean #define READ_WRITE_LEN UINT8_C(8) here?

i  do but stil same 😞 

i add picture. please help me 

thank you for your ansver.

Hi @MESS , 

Sorry for late response. 

Did you solve your issue? If not, could you capture your data and share it with me? 

Thank you.

Merhaba Minhwan 

hala bu sorunu yaşıyorum.

Hata [-9] : Yapılandırma yükleme hatası. Konfigürasyonun sensöre yüklenmesi sırasında arıza gözlemlendiğinde meydana gelir.

BMI270-Sensor-API kütüphanelerini  kullanıyorum  

Tüm kodlarımı ekliyorum. 

ve bu benim yazma ve okuma işlevlerim.

BMI2_INTF_RETURN_TYPE bmi2_spi_read(uint8_t reg_addr, uint8_t *reg_data, uint32_t len, void *intf_ptr)
{
(void)(intf_ptr);
statik uint8_t txarr[500];
uint8_t rxarr[500];
txarr[0] = 0x80 | reg_addr;

nrf_drv_spi_transfer(&spi, &txarr[0], 1, rxarr, len+1 );

for (int i = 0; i < len+1; i++)
{
*(reg_data + i) = rxarr[i+1];
}

BMI2_INTF_RET_SUCCESS'i döndür;
}

BMI2_INTF_RETURN_TYPE bmi2_spi_write(uint8_t reg_addr, const uint8_t *reg_data, uint32_t len, void *intf_ptr)

(void)(intf_ptr);
uçucu statik uint8_t txarr[500];
txarr[0] = reg_addr;
for (uint8_t i = 0; i < len; i++)
{
txarr[i + 1] = *(reg_data + i);
}

nrf_drv_spi_transfer(&spi, &txarr[0], (uint16_t)len + 1 , (void *)0, 0);
BMI2_INTF_RET_SUCCESS'i döndür;
}

Bana yardım için teşekkür ederim 🙂
