DRV8353RH-EVM: Compatibility with LAUNCHXL-F28379D

Imanol,

Unfortunately the DRV8353RH-EVM is not compatible with the launchpad family. Only the included adapter board is compatible.

This being said, the included MCU breakout board has similar features to a launchpad, is there something you are unable to do using it? We can help.

Regards,

Hello Adam!

First of all thank you for your answer. I will try to explain the context:

I am currently working on the control of a "strange" eBike that has three control loops.

1 - A vector control for the current loop.
2 - A speed control loop.
3 - Speed command generator loop (based on some user inputs).

I decided to use a LAUNCHXL-F28379D so that we would not have any issue when executing the current control loop and managing the inputs and outputs every 125 micro seconds, executing the speed control loop every 50 ms, and executing the speed command generator every 200 ms with an internal clock speed of 200 MHz. I also use the second CPU to transmit via SCI the values of some variables of the control that is implemented in CPU1. These values are sent via IPC.

I also need to manage some external inputs and outupts (1 ADC input and 8 Digital signals) appart from the ones that the
DRV8353RH-EVM provides. So the included board does not have enough IO ports...

I program everything with the embeded coder support package for C2000 processors (Matlab/Simulink). I am not good enough programming C/C++.

I hope that is helpful.

However, I do not understand why the Launchpad is not compatible. As far as I know (excuse me if there is any obvious mistake), the GPIO Voltages seem to be compatible, and I checked the schematic of the DRV8353RH-EVM and the analog signals can be read with my launchpad. The only issue that I found is that the DC bus voltage feedback needs to be taken to another pin, because there is not any ADC input in the one that the DRV8353RH-EVM sends it to.

Is there an issue related to the size or the separation of the J1 and J2 connectors? I can place the Launchpad some other place wich is not on top of the DRV8353RH-EVM.

I hope to hear from you soon!!

PS: The hardware configuration is the following one:

- Rated motor current = 15 A
- Battery Voltage = 58.8 V (max)
- Switching frequency = 8 kHz
- Motor type = BLAC
- Max power (traction) = 350 W
- Max power (electrical braking) = -756 W

Hello Adam,

I understand that it is not designed for my launchpad.

Thank you,

- Imanol

By the way, do you know any alternative evaluation module/booster pack that can work with my requirements?

Hello Adam,

I don't understand what you mean with "spin your own board". Do you mean that I can build a custom board? Or is it that I can use the DRV8305 booster pack??

If it is the first one, any tip/tool/tutorial?

Thank you again!

(I hope these are the last questions)

Hello Adam,

First of all thank you for all of your patience. 

I know which the aim of the boards should be, but as they are very capable for supplying low power motors, I use the Launchpad-Boosterpack platforms as a fast prototyping solution to test the control algorithms that I design. This allows me to debug the system much faster than I would if I also had to design the PCBs. That is the reason why I was looking for another similar board.

I will try to program the included control board. If it is not possible, I may need to start designing a custom board, as you said.

Thanks for your answers!
