Hi, I'm using nrf52832, sdk15.3. I have 4 pressure sensors connected to a multiplexer (MUX) chip. And the output of the MUX is connected to channel A0 of the nrf52832. I use an app timer to trigger the ADC sampling manually. The tick equals 1000 ms,
app_timer_create(&m_test_timer, APP_TIMER_MODE_REPEATED, test_timeout_handler); app_timer_start(m_test_timer, APP_TIMER_TICKS(1000), NULL);
How can I read the 4 sensors sequentially in the test_timeout_handler function? I used a "for loop" to do it. But the ADC only sample one time when test_timeout_handler() got called. Here is my test_timeout_handler,
static void test_timeout_handler(void *p_context)
{
int i;
for (i = 0; i < 4; i++) { //read pressure sensors
set_mux(i); //select the mux channel.
//delay_ms(5);
u_adc_start_sampling(); //start sampling
}
... //other tasks
}
I can not make the tick smaller (e.g. 10ms), and then read the pressure sensors one by one. Because the test_timeout_handler() has other tasks to do. So, should I use another app timer inside the test_timeout_handler() function or there are better ways to do it?
