Hello,
I'm developing a program using nrf52832 DK and SDK V15.
I want to activate the SPI transmission when NRF_RADIO->EVENTS_END occurs using the PPI. I follow the PPI example that I found in the SDK. When I insert in my code the pp_init()
function
static void ppi_init(void)
{
err_code = nrf_drv_ppi_init();
//I stuck here, before nrf_drv_ppi_channel_alloc() function
err_code = nrf_drv_ppi_channel_alloc(&m_ppi_channel1);
err_code = nrf_drv_ppi_channel_assign(m_ppi_channel1,(uint32_t)&NRF_RADIO->EVENTS_END, nrf_drv_spi_start_task_get(&spi));
nrf_drv_ppi_channel_enable(m_ppi_channel1);
}
I get stuck in a loop (the code jump directly to ther else statement):
/**
* Function examines current header and omits pushed strings and packets which are in progress.
*/
static bool invalid_packets_pushed_str_omit(nrf_log_header_t const * p_header, uint32_t * p_rd_idx)
{
bool ret = false;
if ((p_header->base.generic.type == HEADER_TYPE_PUSHED) || (p_header->base.generic.in_progress == 1))
{
if (p_header->base.generic.in_progress == 1)
{
switch (p_header->base.generic.type)
{
case HEADER_TYPE_STD:
*p_rd_idx += (HEADER_SIZE + p_header->base.std.nargs);
break;
case HEADER_TYPE_HEXDUMP:
*p_rd_idx += (HEADER_SIZE + p_header->base.hexdump.len);
break;
default:
ASSERT(0);
break;
}
}
else
{
*p_rd_idx +=
(PUSHED_HEADER_SIZE + p_header->base.pushed.len + p_header->base.pushed.offset);
}
ret = true;
}
return ret;
}
