Missing boards TMCM 0930 and TMCM 1230 #72

Closed PWiljes closed 9 months ago

PWiljes commented 2 years ago

Hello,

can you please add the boards TMCM 0930 and TMCM 1230?

Thanks

We finally have the TMCM-1230 in PyTrinamic. Because TMCM-1230 and TMCM-1231 firmware is almost identical, we named the class TMCM123x_0_1, which can be used for both modules. Under examples/modules/TMCM123x_0_1 there are examples.

Concerning the TMCM-0930, what would be the use cases to have it in PyTrinamic? This is a control/communication module only. It is able to control TMCM-1230/TMCM-1231 modules standalone for example. With PyTrinamic there would be no need to have this module in the system.

Sometimes during experiments, one needs to drive motors synchronized as good as possible. But not in stand-alone mode, the motion needs to be triggered by some software scan routine on a linux machine. I thought that might be a job for the 0930 but maybe I got the idea of that module wrong.

For now, we are fine to trigger those motions with some time delay. And for the future, we will see.

Thank you for your reply. The TMCM-0930 would just send successive RS485 messages to each module. Synchronized move is not implemented at the moment. Using CAN directly would be a good alternative, as you could achieved very low delays (not sure if you do that already or using RS485). Using a multi axis board would be another, maybe even better solution.
