Starterware/TMDSIDK437X: Is there any library/source code available for ADC1?

Part Number: TMDSIDK437X

Tool/software: Starterware

Hi,

I use idkam437x with ccs 6.1.2 and sdk 2.1.1.2.

Based on the examples presented in sdk Starterware, I have written some code utilizing the adc0 module. However, there seems to be neither an example nor the libraries to support the adc1 module.

If I want to use the ADC1, should I use the functions declared in tsc_adc_ss.h or there is no support for this module in Starterware?

Thanks

JJ

    JJ,

    The magnetic card reader function is not supported on the AM437x product family. ADC1 should only be used as a general-purpose ADC when using an AM437x device. So I assume you use ADC1 just as general purpose.

    The ADC driver in tsc_adc_ss.h and tsc_adc_ss.c are written with adc_base + offset style. You can get the ADC1 base address from adc_base = CHIPDBBaseAddress(CHIPDB_MOD_ID_ADC1, 0);

    The ADC register layout are almost the same by looking at Table 11-4 and Table 12-6 in AM437x TRM, except that ADC0 has extra registers at offset 0x34 and 0x50.

    So, you can use the same API for ADC1 with the correct base address.
