Part Number: AWR1843BOOST

Hi everyone,

I have the same problem as the linked one. Also my current environment is IWR1843BOOST and SDK 03_05_00_04.

I need to use the PIN D14 but it is not defined in pinmux_xwr18xx.h but it is done in pinmux_xwr16xx.h

Do I have to use other version? Is ther any muxing that I can copy and work with?

Also it looks that it is not defined from GPIO39 to GPIO46, is there any place to find them?

Many thanks for the support,

Javier

Hi,

I don't think these pins are supported on AWR1843.

Please give us some time to look into this

thank you

Hi Cesar,

We are using this PIN because we found it available in the datasheet:

IWR1843 Single-Chip 76- to 81-GHz FMCW mmWave Sensor datasheet

Best regards,

Javier

Hello Javier,

In the IWR1843 datasheet (the same link that you have putup in the above post) , pin D14 is analog ADC channel input. Its not a digital pin. Please check the datasheet again.

Vivek

Hello Vivek,

Many thanks for your answer. Now, I see that it is really defined as ADC instead of GPIO. This misunderstood came from table 4-1 where is also defined GPIO39 to GPIO46 and specify that D14 is also a GPIO. I checked the datasheet of AWR1843 and there is not that definition.

Best regards,

Javier
