Posted on April 22, 2015 at 12:51Hello Erwan,
Referring to below mail, I have configured an ADC channel for SPC560D30L1. I am using
linear buffer with
maximum sequential set to
1. I have configured the callbacks to read the ADC count and to convert it to voltage value. Here, I have observed that ADC conversion is required to be initiated (ADC_Start_Conversion) in order to read the new input value. I am doing this on a key press. How can I configure the ADC for continuous read and get the updated count value when input changes?
Please note that I have 3-4 more ADC channels independent of each other where I required similar functionality. How to implement this?
Thanks in advance for your help.
Mike.
Please find below the callbacks,
/*
* ADC streaming callback, the name is defined in the ADC graphic
* configuration.
*/
size_t nx = 0, ny = 0;
void ADC_conversion_callback (ADCDriver *adcp, adcsample_t *buffer, size_t n)
{
(void)adcp;
if (samples == buffer)
{
nx += n;
}
else
{
ny += n;
}
g_adc_val = samples[0];
g_adc_vol = ((5.0/4096)*g_adc_val);
}
/*
* ADC error callback, the name is defined in the ADC graphic
* configuration.
*/
uint32_t errore = 30;
void ADC_error_callback (ADCDriver *adcp, adcerror_t err)
{
(void)adcp;
errore = err;
osalSysHalt(''ADC failure'');
}
