hello ,

Which MCU do you use ?

please check the test Application in SPC5 families in SPC5Studio (ADC part)

Best Regards

Hi Erwan,

i'm using SPC57 (SPHAERO). Which one i need to select? 

[ODOUV.1]

Hello,

in SPC5Studio, click on select you product family:select a product and click on next:select a driver example:

and finally select the demo application and click on finish:

 

It is the same answer for any driver example, any product family

Best regards

what is different between "saradc_lld_cfg.h" and "adc_lld_cfg.h"? i got confuse between these two.

[ODOUV.1]

saradc_lld_cfg.h is the only one used on SPHAERO product, do not mind about other.

What means by {8U,9U} and {0U,0U} ? One more thing whats is "anp" stand for and function?.

[ODOUV.1]

be careful, you are not looking to the SPHAERO demo (SPC574S) but to the VELVETY one (SPC570S) do you confirm you product is SPC574S ?

[ODOUV.1]

U is used to define unsigned immediate for MISRA purposes

anp, I suppose it stands for analogue port ? as it is used to select analogue channels

[Angle]

if i used the potentiometer on pin PI[1] and PI[2], which part in the code that explain about the pin number/ where i need to modified the code for pin number?

[ODOUV.1]

ion default example, the SARADC supervisor0 is used:

 /* change driverUnderTest value to test others SARADC modules. */

 driverUnderTest = &SARADC12DSV;

corresponding into low level driver component to this check box:

 

the channel used in channel 1:

uint8_t anp[NUMOFCHANNELS] = {1U};

in Reference Manual, it correspond to pin PB[6]:

 

you can verify it in the outline of the pinmap tool:

ANP1 correspond to pin PB[6]

On your side, if you want to use for example PI[1] as analogue input, then use the pinmap tool to do so

 

and then you will have to enable channel5 ANP5 of ADC_12b_1

[Angle]

ohh i understand. Btw where can i get this reference manual ?

[ODOUV.1]

of course you will have to reconfigure the low level driver component to enable ADC_12b_1 and configure channel 5 of ADC_1 instead of channel1 of ADC_SV0 which is the default example

[ODOUV.1]

go to www.st.com

search for you product (eg SPC574)

you will find associated documentation and the reference manual
