Hi,

You should set the SES project configuration from "Release" to "Debug", and check what function is returning the error-code that triggers the error-handler and try debugging your application.

yes,,but inside nrf_drv_vcnl4020_read_registers() function i have used

err_code = nrf_drv_twi_tx(&m_twi_instance, vcnl4020_ADDRESS, &reg, 1, false); and

err_code = nrf_drv_twi_rx(&m_twi_instance, vcnl4020_ADDRESS, p_data, length); functions only..it is nothing different...

which are originally

err_code = nrf_drv_twi_tx(&m_twi, LM75B_ADDR, reg, sizeof(reg), false);

and

ret_code_t err_code = nrf_drv_twi_rx(&m_twi, LM75B_ADDR, &m_sample, sizeof(m_sample)); functions used in sdk(LM75B example twi_sensor)

i just created new function for my convenience..thats it..

Hi,

[quote user="asmita_patil"]yes..i did all changes. ..now it is working...[/quote]

Good to hear it works.

nrf_drv_vcnl4020_read_registers() is not developed by us and out of our support.

If you have further questions, please create new cases for them. They are already faraway to the title.

my code is getting stuck at nrf_breakpoint_cond...

i changed sdk_config.h as suggested

#ifndef NRF_LOG_ENABLED
#define NRF_LOG_ENABLED 1

#ifndef NRF_LOG_BACKEND_RTT_ENABLED
#define NRF_LOG_BACKEND_RTT_ENABLED 1

somebody can help???

this is where code is stuck

and it is the definition

any help would be appriciated...thank you

yes..i did all changes. ..now it is working...but the problem is that it reads the registers but all the valuse are getting in m_sample variable....i am returning *p_data from read function and have assigned a variable to catch values in..but they are not displaying in those variables....it is only remaining in m_sample..

what could be the reason.??

this is what i am doing

rslt_MSB = nrf_drv_vcnl4020_read_registers(0x87,&m_sample,1); // command to read result register 0x87 (MSB bits) of vcnl4020

rslt_MSB = m_sample; //m_sample holds the values of result register..copy it to rslt_MSB variable.

rslt_LSB = nrf_drv_vcnl4020_read_registers(0x88,&m_sample,1); //command to read result register 0x88 (LSB bits) of vcnl4020

rslt_LSB = m_sample;

am i doing it right ??

and i have integrated twi_sensor into eddystone...can you halp..??

Thank you.

Hi,

Could you try to enable TWI_ENABLED in the sdk_config.h?

// <e> TWI_ENABLED - nrf_drv_twi - TWI/TWIM peripheral driver - legacy layer
//==========================================================
#ifndef TWI_ENABLED
#define TWI_ENABLED 1
#endif

When you are integrating twi_sensor into ble_eddystone, you could refer to the sdk_config.h of twi_sensor.
