Hi, all.
I m trying to combine two example spi + timer using nRF52832.
But spi_event_handler function in the ex spi and timer event in the ex timer are crashed.
If I insert source code "nrf_drv_timer_enable(&TIMER_TEST);", program is died.
I want to result this problem.
Can you help me?
source code is as below.
//const nrf_drv_timer_t TIMER_TEST = NRF_DRV_TIMER_INSTANCE(0);
/**
* @brief SPI user event handler.
* @param event
*/
void spi_event_handler(nrf_drv_spi_evt_t const * p_event,
void * p_context)
{
spi_xfer_done = true;
// NRF_LOG_INFO("Transfer completed.");
// if (m_rx_buf[0] != 0)
// {
// NRF_LOG_INFO(" Received:");
// NRF_LOG_HEXDUMP_INFO(m_rx_buf, strlen((const char *)m_rx_buf));
// }
}
///**
* @brief Handler for timer events.
*/
void timer_event_handler(nrf_timer_event_t event_type, void* p_context)
{
}
int main(void)
{
APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
NRF_LOG_DEFAULT_BACKENDS_INIT();
NRF_LOG_INFO("SPI example.");
nrf_drv_spi_config_t spi_config = NRF_DRV_SPI_DEFAULT_CONFIG;
spi_config.ss_pin = SPI_SS_PIN;
spi_config.miso_pin = SPI_MISO_PIN;
spi_config.mosi_pin = SPI_MOSI_PIN;
spi_config.sck_pin = SPI_SCK_PIN;
APP_ERROR_CHECK(nrf_drv_spi_init(&spi, &spi_config, spi_event_handler, NULL));
// Timer
uint32_t time_ms = 1000; //Time(in miliseconds) between consecutive compare events.
uint32_t time_ticks;
uint32_t err_code = NRF_SUCCESS;
//Configure TIMER_BMS for generating simple light effect - leds on board will invert his state one after the other.
nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG;
err_code = nrf_drv_timer_init(&TIMER_TEST, &timer_cfg, timer_event_handler);
APP_ERROR_CHECK(err_code);
time_ticks = nrf_drv_timer_ms_to_ticks(&TIMER_TEST, time_ms);
nrf_drv_timer_extended_compare(
&TIMER_BMS, NRF_TIMER_CC_CHANNEL0, time_ticks, NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK, true);
nrf_drv_timer_enable(&TIMER_TEST);
while (1)
{
spi_xfer_done = false;
__WFE();
__WFI();
// nrf_drv_spi_transfer
NRF_LOG_FLUSH();
}
}
