Hello,
At the following line
const static nrf_drv_twi_t m_twi_master = NRF_DRV_TWI_INSTANCE(MASTER_TWI_INST);
I get the error:
hal.c(35): error: #20: identifier "NRF_DRV_TWI_INSTANCE_0" is undefined
When looking further it seems likein the following code from nrf_drv_twi.h is greyed out
#define NRF_DRV_TWI_INSTANCE(id) NRF_DRV_TWI_INSTANCE_(id)
#define NRF_DRV_TWI_INSTANCE_(id) NRF_DRV_TWI_INSTANCE_ ## id
#if NRFX_CHECK(NRFX_TWIM0_ENABLED)
#define NRF_DRV_TWI_INSTANCE_0 \
{ 0, { .twim = NRFX_TWIM_INSTANCE(0) }, true }
#elif NRFX_CHECK(NRFX_TWI0_ENABLED)
#define NRF_DRV_TWI_INSTANCE_0 \
{ 0, { .twi = NRFX_TWI_INSTANCE(0) }, false }
#endif
#if NRFX_CHECK(NRFX_TWIM1_ENABLED)
#define NRF_DRV_TWI_INSTANCE_1 \
{ 1, { .twim = NRFX_TWIM_INSTANCE(1) }, true }
#elif NRFX_CHECK(NRFX_TWI1_ENABLED)
#define NRF_DRV_TWI_INSTANCE_1 \
{ 1, { .twi = NRFX_TWI_INSTANCE(1) }, false }
#endif
When I go even further and look in my SDK_config.h I can clearly see that all TWI and TWIS and TWIM entries are set to 1 and the instances are also set to 1:
// <e> NRFX_TWI_ENABLED - nrfx_twi - TWI peripheral driver //========================================================== #ifndef NRFX_TWI_ENABLED #define NRFX_TWI_ENABLED 1 #endif // <q> NRFX_TWI0_ENABLED - Enable TWI0 instance #ifndef NRFX_TWI0_ENABLED #define NRFX_TWI0_ENABLED 1 #endif
What else can be the problem?
