mrrwa / loconet2 Goto Github PK

I have started trying to port the Loconet library to Arduiono Nano Every. Right now it seems to me that there are enough differnces between the avr and avrmega ICPs so that it will require more changes than simply adding avrmega specific defines in ln_config.h ,
Would it make more sense to do this development in this library instead of the old codebase?

What is the ambitions for the two different Loconet libraries? Is the intention for Loconet2 to be the way forward and replace the old one?

Hello!
I'm trying to use and modify this library for my purposes and noticed that I cannot send packets from inside notify... methods, this makes responding to requests problematic. The issue is due to actual sending bits and receiving bits happens in the same freertos task and while(lnState == LN_ST_TX) loop inside sendLocoNetPacketTry basically blocks the task it's running on. When one calls send method from notify... function, that loops basically deadlocks the sending task.

I think it would be better to move actual bit sending (and receiving) to timer functions and only handle receiving of bytes in the task. This way, waiting for send to complete won't block sending which is done in timers.

Also, what's the development status of this library? I've noticed that it hasn't been updated for a while.

Unlike the AVR library, because of the way the receive/transmit task's state machine works, you don't receive your own transmissions to Loconet.

I have been experimenting with amending the code to add the bits into the receive byte buffer (lnCurrentRxByte), and shifting them as the receive code does, as they are put onto the bus.

When a byte has been transmitted, and the transmit task gets the next byte, process(lnCurrentRxByte) method is called, to build the message up the main Loconet message buffer as if it was receiving a byte normally.

In the case of a collision, the lnCurrentRxByte is cleared ready for either retrying transmission or receiving a byte from the bus.

My tests show this is working, and the notifyX functions get called as expected. So, for example, I can transmit a SwitchRequest message, get notified and act on it on the same ESP32.

I'm sure there are cases where this won't work, and I need to see what happens if a collision happens in the middle of a multi-byte message, where some bytes are already in the main Loconet message buffer (although I guess this can happen when receiving too, so this may not be a problem).

Thanks,

Richard

Hi,

I'm trying to compile the 'Basic-Listener-Pico.ino' but this gives the error: 'LocoNetStreamPico' does not name a type;
I also get a WARNING: library LocoNet2 claims to run on esp32 architecture(s) and may be incompatible with your current board which runs on rp2040 architecture(s).

Like to use LocoNet2 on a RPi Pico W as a router to MQTT.

Hello,
i want to setup a Throttle with an ESP32. but in the Init phase the CPU looks up.
I habve an NodeMUC ESP-32s wiht an ESP-Wroom32 Chip. Some other Tests with TFT ans so an are ok.

I have the Arduino IDE with the last ESP 1.0.1 installed. (Updated after the problem beginns)

For me its crash at Throttle.init (0,0,0, ThrottleID); //erzeuge Handregler
I don't know whats wrong.
Any change to help ?
Tank you very mutch for a hint.
Jake
