Dear Ti Team
I've been struggling with how to implement an SCI program myself.
Then I saw this post quoted.
But I don't have permission to download the related files inside, where can I find this example?
Note: The board I used is the TMS570LC4357HDK.It's supposed to be universal.
Hi Gundavarapu
It doesn't matter. It's not urgent. I actually simulated SPI via GPIO, but only at 500KHz. I was also worried about the CPU load, because it has a lot of tasks.
It would be best if we could simulate SPI with HET.
The link page you gave me could not be found. Is it the problem of copying?
Hi Gundavarapu,
Thank you for your reply. I'm not going to use HET to simulate SPI operations for the time being. I plan to use HET to simulate two serial ports, but I have some questions during the process and still need your help to answer them.
1.In the HET serial port simulation code, I originally intended to create a new project and transplant the reference code over. However, I found that the original project had two folders that were grayed out. I couldn't generate folders with the same attributes in the new project, so I made the modifications in the original project. Could you please explain what the concept is behind the grayed-out folders as shown in the following picture?
2.In this reference project, het1[0] is TX and het1[2] is RX. If I want to change the pins of TX and RX, can I just modify the highlighted part in HET_EMU_SCI.het as shown in the figure and then compile directly?
3.If I want to use het to simulate the function of two serial ports, how should I operate?

If you right click on the folder and then you can see the option called "Exclude from Build"
If you click on this option that will gray out the corresponding folder, this means the corresponding folder will not be built while building project, basically those folders will exclude from build.

Yes, you can do that.

Let me verify it, i never tried this. All you want is that you want to simulate two serial ports (UART's) using the same code, right?

Yes, I want to, I saw below in the application manual, it probably means that you can use het1 or het2 to simulate two serial ports, I don't know if I understand correctly.
