Hi everyone. I will use spi accelerometer adxl362 for my project. My microcontroller is msp430g2230. Is there anyone who worked with project similar to mine? Could you post some code examples?
Please note that the example code is developed based on ADI MCU ADUC7026. SPISTA is the SPI status register of ADUC7026, but not for your MCU. You need to find the corresponding register name in your MCU.
Refer to MSP430, you can find something useful in the link below.
Decent Syntax explanations:
Example code when using the MSP430 4-sire SPI as a Master:
My colleagues may have better examples for you, but I know that if you search "ADXL362 code," you will find quite a few search results. One example is in the Linux software, which likely would provide a good starting point for you.
Hope that helps.
Thank you for concern!
But I don't know how linux driver code can help me with msp430? Do you mean it can help for algorithm?
I understand your perspective but if you are accustomed to writing code for embedded processors like the MSP430, I think that you are going to find that managing the SPI interface in ADXLxxx, ADXRSxxx or ADIS16xxx is pretty simple. I offered the Linux driver as an example that others have used to learn how the interface operates, through an actual code example. I hope that helps.
By the way, the Arduino examples on this forum are another good place to start:
Again, my colleagues may have specific examples, but I happened to be looking at these code examples for another reason, so I thought I would share them for you, in case they are busy and cannot answer this for a few days.
One more quick example for you. Again, not specifically for the MSP430, but offer another example of a C-code that manages the interface with the ADXL362, this time for a FPGA.
I Google-searched "MSP430 ADXL362 code" and noticed quite a bit of forum chatter but I didn't see any code references that came with confirmation of correct function.
Attached are some example code for you. ADXL362 supports the standard SPI and follows CPHA = CPOL = 0. You just need to set SPI speed and CPHA and CPOL, then start the SPI communication. The max SPI speed of ADXL362 is 5MHz.
Hope these can help.
Thank you guys... When I finished my work, I will share.
Hey. I have a question.
while ((SPISTA & 0x08) != 0x08) ;
In this line, is it waiting to complete the transmission? If it so, how and what is the SPISTA register? I will guess it for my microcontroller.
