Hey, i tried the same program, and i can't enter the print_identity function. The loop executes continuously, but except the twi started message , nothing else is printed

Hi lydie,

checkout the LIS2DH12 datasheet p.31: https://www.st.com/resource/en/datasheet/lis2dh12.pdf

The expected result is 51 (hex 33, bin 00110011).

EDIT 2019/07/27

"According to" Mouser https://eu.mouser.com/ProductDetail/STMicroelectronics/LIS2DH12?qs=yXzv9R%2FF42Ia01kPyHCTbw== the LIS2DH12 and a couple other sensors are EOL (https://www.mouser.com/PCN/STMicroelectronics_9055.pdf). Depending on your needs you might need to find a suitable replacement.

Looks like I spoke too soon: according to ST https://www.st.com/en/mems-and-sensors/lis2dh12.html the LIS2DH12 is still active ...

/EDIT

It's ok, it works. But what is the expected result of who_am_i read and the function print_identity with this line:

NRF_LOG_INFO("Identity: %d", *((uint8_t *)p_register_data));

because you define it:

LIS2DH12_INSTANCE_DEF( m_lis2dh12, &m_nrf_twi_sensor, LIS2DH12_BASE_ADDRESS_HIGH );

Where, exactly, do you get that?

Hi,

how do you know the sensor instance name (m_lis2dh12)? I try the same code and I have an error:

macro names must be identifiers

in lis2dh12.h

Thanks!

Hi everyone,

sorry for the delayed reply. I managed to get it working thanks to Spegs21 - I was oblivious to the fact that you have to init m_nrf_twi_mngr and m_nrf_twi_sensor to configure the pins ...

Edvin the UART debug output went as follows

<info> app: TWI sensor example started.
<info> app: Here.
<error> app: Fatal error
<warning> app: System reset

My suspicion is that due to the uninitialized m_nrf_twi_mngr / m_nrf_twi_sensor the driver didn't knew which pins belonged to the sensor / was getting an "uninitialized something" error at some point.

It works fine now with the code provided below. Take note that I'm using the nRF52 DevKit and have hooked up the sensors SCL to P0.27 and SDA to P.026.

Whoops! That fixed it. I changed that for some reason looking at your above post. Before it was failing because I wasn't initiating twi_sensor.

Edit: Actually it worked because it programmed the DK instead of the external board which does't have the low frequency oscillator. Is it required for TWI?

Edit 2: Changed it to RC in SDK config and it worked. I'll take that as a yes to my question.

Edvin — Mon, 18 Jun 2018 14:13:24 GMT

You are checking the address of err_code on line 27 in your snippet. It is obviously not 0, so APP_ERROR_CHECK(&err_code) stops the application. Remove the "&" in APP_ERROR_CHECK(&err_code); and see if that helps.

Maybe you could check the err from :

ret_code_t err = lis2dh12_init(&m_lis2dh12);

What is it?

Hi aaronxu ,

I'm too trying to setup the LIS2DH12 driver to read out the WHO_AM_I register. I've adapted the twi_sensor example code according to my needs and your code snippets. Due to some previous issues when compiling I used the sdk_config.h from the twi_master_using_nrf_twi_mngr example.

When I run the attached code the application starts, runs to the "Here." debug print, crashes and resets to continue in an endless cycle.

Would you mind sharing a minimal example on how to read out the WHO_AM_I register using the drivers or point me in a general direction to keep searching?

Hello,

I am sorry for the late reply.

I don't have a LIS2DH sensor to test any of this on, but the parameters: LIS2DH12_MIN_QUEUE_SIZE and MAX_PENDING_TRANSACTIONS means the following in the application:

NRF_TWI_MNGR_DEF(..., MAX_PENDING_TRANSACTIONS, ...)

The second parameter of NRF_TWI_MNGR_DEF(...) is the size of the transaction queue. See NRF_TWI_MNGR_DEF() on infocenter.

NRF_TWI_SENSOR_DEF(..., ..., LIS2DH12_MIN_QUEUE_SIZE)

The third parameter of NRF_TWI_SENSOR_DEF(...) is the buffer size of the TWI communication for that sensor. See NRF_TWI_SENSOR_DEF() on infocenter.

Again, I haven't got any LIS2DH sensor to test this on, so I haven't tested this driver before. But I suppose that the sensor def is the queue of a single transaction in bytes, while the TWI_MNGR_DEF is the max number of pending transactions.

Best regards,

Edvin

New commit:

I found the reason of this Hard fault is that, I use

lis2dh12_data_read(&m_lis2dh12, lis2dh12_data_read_cb, &accel_data, sizeof(accel_data));

but the last parameter was multi by 6 inside lis2dh12 driver, so it's bigger than LIS2DH12_MIN_QUEUE_SIZE.

So I change is to 1 and it work.

But I still have question, How big can I set the "LIS2DH12_MIN_QUEUE_SIZE". And do I need to set MAX_PENDING_TRANSACTIONS bigger than LIS2DH12_MIN_QUEUE_SIZE?
