Tutorial:Identify section of Java Code that execute the Daisy Chain Byte/Data Flow : I.E Header ,Status, Addresses,Data

[aedford]

Trying to look under the hood and relate how the data flows inside the Daisy Chain wiring - Max Spark Contollers, Rio , PDP circuit ( Green, Yellow wires ) What in the code segments initiates the flow of data and how I can inter relate the code statements , variables ,values, functions to the Header, Status, Address, Data ,Bytes ( provide an example ) Using the 2023 Rev Ion Starter Bot for Hardware , Java Code for software ( for West Coast Drive Train ,, Manipulator ,Grippers- Neo bushless motors ). We like to walk thru the entire sequence , code ,transmission, hardware Reference articles Daisy Chain Implementation for Serial Peripheral interface ( for bushed motors ) by Texas Instruments Would like to be able to illustrate that interface ( low level for them , higher level for me ) to the FRG team #4398 if not a tutorial - can some educate me ( Allan Edford , mentor ) - Team 4398 Thanks

Do you mean the CAN wiring?

The article you mentioned seems to be talking about things via SPI and none of this is controlled with SPI (there is an SPI port on the RIO but it is usually only used for sensors and has issues at that).

We don't really go into low level into the docs, nor do we want to recommend teams to. Can your clarify your issue?

Yes

I'M a retired engineer and this is mainly for my benefit I like to take things apart Walking thru the Java code we are using on the frc team 4398 robot that got my interest also was exposed to SPI thru robot on line workshops and projects at an Engineering Academy where I 'm on the Guidance board Traverse City Mi Most of this stuff I studied including AI after retirement I has become a hobby

Oh ! I would still be interest in the details of the communication platform to get a feel and an understanding of it I,'m amazed at the sophistication that must have gone into the code development in order for the K 12 kids to use it's top level

Have found Texas Instruments and other tutorials on CAN that have broaden my understanding of the network Also tutorials on Daisy Chains Have sufficient info to feel more comfortable Thanks
