Hello,
I am using MBDT for S32k3xx EVB.
What is exact functionality of ADC's 'setup result buffer' block?
I need to know following points about that-
1. What type of data it need and its data type? Please give an example.
2.Is it a address ?
3.How to give that data using data memory read?
Hi,
A quick introduction about the MBDT workflow for S32K3xx:
The MBDT for S32K3xx generates code based on RTD (Real Time Drivers) MCAL components.
To learn more about how to use and configure these components, open the block help from the block mask and look in the Function section for your desired function:
There you can find information about the block's inputs and outputs. In addition, the Code Generation section of the block help contains a link to the component's RTD User Manual and, in some cases, a link to the AUTOSAR Specification if the component is AUTOSAR compliant. These documents contain information about the C functions that our toolbox blocks implement.
Based on the RTD or AUTOSAR function specifications, you need to select the appropriate data type. You can check in our examples how to declare a data store memory like Adc0Group0_ResultBuffer. Double click on a data store memory and take a look in the Signal Attributes section.
In the RTD or AUTOSAR documentation, the Adc_SetupResultBuffer function requires a pointer with the address of the result data buffer. When you connect the data store memory to the Adc_SetupResultBuffer block, the address of the data store is automatically computed by our block and used in the generated code.
Hope this helps you.
Cheers,
Victor
Hi, @avinashstarkenn,
Each example provided with our toolbox has a readme next to them that contains information about its functionality, the hardware and software settings that need to be done. You will find information about the expected results of the application.
The Simulink model C code generated from the application can be viewed in the Embedded Coder menu, after pressing the View Code selection. Here you can find the C code generated by a specific block.
This code is cross-compiled and linked into an executable file for the microcontroller. Hence, the address of the result buffer is a microcontroller address. You can use the FreeMASTER tool as in the s32k3xx_adc_single_read_s32ct example to read the values from the result buffer in real-time. Another method to see the values from the result buffer is to import the application in S32 Design Studio IDE and launch a debug session.
Hope this helps,
Victor
