EVAL-AD74413R Eval board's source code

Hi MarioDJ ,

We will look into this. I will contact the product owner and get back to you.

Hi MarioDJ,

thank you for your query. 

I can reference you to our No-Os drivers page for code/program.

https://wiki.analog.com/resources/tools-software/uc-drivers/ad74413r

Unfortunately we are not able to provide our evaluation GUI codes program/code used at "EVAL-AD74413R Eval board and EVAL-SDP-CS1Z board". 

Please keep me informed if you need any further assistance. 

Regards,

Arnost

Hi APavlik and JCCillion,

Thanks for the response. I want to make sure all channels (in my AIAO board)are reporting the correct or expected value before deploying the AIAO board to the field. 

So, I plan to use your AD7441xR software GUI to check my board (instead of your EVAL-AD74413R Eval board). I

If I know the command and Frame format sent by AD7441xR software GUI to EVAL board, I mimic the same and validate my board. 

Can you please help me get the  "command and Frame Format' of  AD7441xR software GUI?.

Hi MarionDJ,

concerning the frame format please refer to AD74413R datasheet - section SPI INTERFACE AND DIAGNOSTICS ( https://www.analog.com/media/en/technical-documentation/data-sheets/AD74413R.pdf). 

Concerning the commands, AD7441xR software GUI sends commands to configure the AD74413R according the user control panel. I will see, if I will be able to get exact sequence of commands for you, as GUI was developed by third party. I expect, that commands will be very similar or same as presented at  No-Os drivers (https://wiki.analog.com/resources/tools-software/uc-drivers/ad74413r) - loading desired configuration to registers, setting desired mode of operation, controlling DAC or reading ADC. Details description how to configure part can be found at the datasheet.

Arnost

Hi APavlik,

Thanks for the info. I will use this  sample code  and work to get the values from all the channels. If anything, I will ping you. 

Where can I get the same code for  iio_app_run(iio_devices, NO_OS_ARRAY_SIZE(iio_devices)); ?

If I see the code of  iio_app_run(), it will help in my development and debug activity. 

Hi MarionDJ,

I will contact my college concerning the same. I am not sure, if those were developed also. 

Regards,

Arnost

Hi APavlik,

Thanks for the input. Once you get the code, please share with me 

Hi MarioDJ ,

You may find the iio_app_run function here: https://github.com/analogdevicesinc/no-OS/blob/master/iio/iio_app/iio_app.c#L428 . Also, the sample code showcased (in the documentation Arnost previously linked) is part of this No-OS project https://github.com/analogdevicesinc/no-OS/tree/master/projects/ad74413r . This was developed using a Nucleo144 board (with an STM32F7 MCU), for which an IOC file is also provided in the same project directory.

If you are not familiar with the No-Os' build system, please have a look at this page: https://wiki.analog.com/resources/no-os/build .

Thanks,

Ciprian

Hi CiprianR ,

Thanks for the info and support. Actually, I have leveraged code from this https://wiki.analog.com/resources/no-os/build . for driver development.  

Here wiki.analog.com/.../ad74413r, they have shared code on how to initialize and verify various channels with different modes. 
I am working on enabling CURRENT_OUT and CURRENT_IN_LOOP modes  in my board. 

But code for both these features are not provided. If I view the sample implementation(CURRENT_OUT and CURRENT_IN_LOOP), I will validate and verify my board. 

Hi all,

As I am adding CRC in my code and I am observing this line ```NO_OS_DECLARE_CRC8_TABLE(_crc_table);``` in  ad74413r.c https://github.com/analogdevicesinc/no-OS/blob/master/drivers/adc-dac/ad74413r/ad74413r.c#L59. I don't get the code for`NO_OS_DECLARE_CRC8_TABLE().  I feel I don't understand that. 

Can I change the code like this, 

```

#define NO_OS_CRC8_TABLE_SIZE   256

#define NO_OS_DECLARE_CRC8_TABLE (_crc_table)    static uint8_t _table[NO_OS_CRC8_TABLE_SIZE]

```

I am not able to find code for this function call no_os_crc8_populate_msb(_crc_table, AD74413R_CRC_POLYNOMIAL); in github.com/.../ad74413r.c
