Hi champs,
I am asking this for our customer.
Do we have any Modbus (over UART) example, better with an external RS485 transceiver?

Hi champs,
I am asking this for our customer.
Do we have any Modbus (over UART) example, better with an external RS485 transceiver?
I think my team is working on the modbus demo. Let me check with my team first.
Hi Yuhao,
It's in C:\ti\mspm0_sdk_2_07_00_05\examples\nortos\LP_MSPM0G3507\modbus,
but it's NOT in
C:\ti\mspm0_sdk_2_07_00_05\examples\nortos\LP_MSPM0L1306
Would you please help confirm why it's in G3507 examples, but it's not in L1306 example?
For example, is there computational power limitation? UART module difference/limitation?
Please help clarify it explicitly.
This is first developed on G3507. But it can also be used with C1106, as their UART module is very similar.
Hi Yuhao,
Let me confirm again.
The Modbus example can also be used in L1306 and C1106, even if their clock rates are much slower than G3507.
Is it right?
Have you checked with customer about the modbus speed rate?
Usually it is between 2400bps and 19200 bps. Why do you think L1306/C1106's clock cannot support modbus?
Hi champ,
Yes, I believe the baud rate can be a key factor here.
The user is just confused why TI does not have such folder for Modbus examples.
Therefore, they are asking us to clarify that.
If so, would you please help check if we can put this folder in the coming MSPM0 SDK update so that the user can be confident?
They will study the example on G3507 first.
The M0 modbus solution is just released in latest SDK, which is built and test via LP-MSPM0G3507 and LP-MSPM0G3519.
And yes we will port it into other M0 devices, which need more tests.
If customer requires this in a short term, please send an email to MSP LSM APPs team and we can check with our software team.
