SPC5Studio configuration

[ssk]

Hello,

I am using SPC5Studio for SPC560D MCU.

1. How can I access CTU configuration from SPC5Studio?

2. How can I configure ADC module for using CTU, one shot conversion vs scan, priorities for EOC etc?

3. Any user guide available for using SPC5Studio effectively? Lot of times, the wizard generated functions are difficult to understand the correct configurations.

Thanks.

Mike.

Hi Mike

I Have the same problem for ADC Module and PWM ST have A refrence for Advanced light control and diagnostics ,it is a good refrence using both ADC and CTU .

I attach a refrence for u but i think u can find on st site .

Hello Mike ,

it is a good idea to use this AN.

Advanced light control and diagnostics using

SPC56xBx and SPC56xCx microcontrollers

2 Choices :

1) use the Patch Mode to update and enable CTUEN in the SPC5Studio ADC driver.

or 

2) use an external ADC driver , use as example ADC Init and CTU init (cf AN)

Thanks Erwan and Nazerian for the reply. But this app note mainly uses discrete settings for different modules. Whether this type of configuration is possible with application configuration? Any document explaining different features for application configuration?

Thanks,

Mike.

Hello Mike ,

You can find some example configurations in the Reference Manual

25.3.3 ADC sampling and conversion timing

25.3.4 ADC CTU (Cross Triggering Unit)

yes ,

it should work

you have to take care 

1) The CTU can be enabled by setting MCR[CTUEN].

 

2) The CTU and the ADC are synchronous with the peripheral set 3 clock in both cases.

3) in the SPC5Studio Driver , 

 

 

you should use Injected Conversion not normal conversion

 

  /* Starts conversion.*/

  adcp->adc_tagp->MCR.B.

NSTART

 JSTART= 1U;

Best regards
