Yes ;) I have already programmed modbus servers to control the slave (with minimalmodbus) but never in slave mode (I haven't found library). Today I will be able to decode all the frames and then send the answers in the right format and with the CRC (manualy) but a library help me a lot :oops: than...

I just want to clarify what you are asking: You want to setup a Pyboard as a modbus slave on an existing TCP network so that it can be controlled by a master device on same network. I presume you want to be able to use the digital inputs/outputs as well as analog in/out. In the past I have used stan...

That is pretty neat.

Julian, good work. While I don't have this sensor, your changes will be useful in figuring out differences between the two ports.

I ran the script you posted. Getting times of around 1.6-1.7 ms using an ESP32 with 4 MB PSRAM running a build of the standard Micropython repo with the module uasyncio as frozen. There were other modules as well in that directory. -- idle -- -- task1 -- -- task2 -- asyncio.sleep(0) = 1701 us 280139...

I'm a total newbie just learning. Is it possible somehow to dedicate one of the two cores for a given task.

Well, that's your call ;) I found cancellation and timeouts rather tricky to implement, but then I'm far too old for this kind of thing; a younger mind might polish them off in a day... The following shows gather being used with timeouts and cancellation (tested on Unix and Pyboard): ---------- Tha...

I'm having issues when rshell is used with a NodeMCU ESP32 board. It is a DEVKITV1. I have filed the following issue with the @dhylands rshell git repo. https://github.com/dhylands/rshell/issues/67 Upon power up of the module, I can rshell into it once just fine. Subsequent attempts at connecting wi...

This is a great start. I'm happy to help. I will take a look to see what areas I can do so. Somewhat of a newbie still.

I too was able to replicate this.

It took a while but I was able to setup the esp sdk toolchain required to build a firmware with the frozen bytecode. Once built everything ran fine with no memory issues.
