I was thinking along similar lines as Steve....

Sorry - I don't have Flowcode 4

Glad you are making headway again.

Let us know how the project goes!

and https://www.furunousa.com/-/media/sites/furuno/document_library/documents/brochures/brochures/s650_st650.pdf - which shows the 4.8/5.6Hz values - though this might be a different part - it looks to be the same as the Airmar replacement? And the rate is per knot so if your boat is going at 20kts ...

Struggled to find them again......

This gives the 26000, 7.25Hz http://www.ohmex.com/p66.pdf

There seems to be a 'fuller' datasheet - but only on scribd (and I didn't want a trial subscription)

Got PicoMQTT to run AOK (on an esp32s3) this morning. Compiled the basic_server example (using the Arduino IDE - setting up the esp32 toolset failed multiple times!) - and then connected using the MQTT Client app on Android. Yesterday connecting failed but today it went smoothly - esp32 connected to...

For interest - there is a MQTT server that will run on the esp32 - PicoMQTT. It is quite limited (5-10 connections) and so far I haven't managed to get it to run - but for 'remote' or low-power scenarios it might be a suitable alternative to the power of a RPi.... Having said which - a Pico is proba...

Possibly - but I couldn't get the timed interval component to compile. I got: from D:\Projects\Flowcode\t1.c:20: D:\Projects\Flowcode\t1.c:2433:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void' Error returned from [avr-gcc.exe] So in theory - you could run a 'check' every 4s (...

Possibly - but I;m not sure I see what extra information you'd get by doing so?

I would either modify the above code to record the time for every (say) 100 pulses OR record the number of pulses over a given interval?

It might be missing the interrupt - you have a 300ms delay in the first macro shown (which i assume is the ISR) - this would likely cause your program to fail. It is very hard to tell from screen shots (no macro names etc) - so please upload your code - however, as version 4 is now no longer support...

Flowcode v4 is now no longer supported - can I suggest you try v11 - you will find a lot has changed for the better...

If you need a non blocking delay you will need to get rid of the delays in your code... A timer interrupt could handle things (and must not contain delays)
