Some more information needed

TheCurly opened this issue · 10 comments

Hi Mark,

First of all, thanks for the great work! After going through the readme file, I still have a few questions:

  • Would you happen to have some more information and pictures that show the connections? Pin 1 is the black cable, correct?
  • Which connector goes where on the LayZspa? I would assume you plug the JST-SM Male into the pump side and the JST Female into the display side, but what are the dupoint connectors for?
  • Do you have any part number for the 4 channel bi-directional logic level shifter US2?

I don't want to take too much risk with a project like this.

Best regards,
Ronny

Nice work I will build this for my vegas . Pump No 54112

I think SV1 is pump side and SV2 display.

Sorry for the delay. I will try and get some pics, I would put a multimeter on the outside pins to check the polarity.

SV1 is the display side
SV2 is the pump side, you might need to adjust the pinout in the code as I notice that the schematic goes to D0 but code is set to 5 which is D1. I haven’t got around to getting another board printed yet so haven’t hit that issue - mine is strung together with cables still.

I don’t have a part number for the level shifter but it’s similar to this: https://www.ebay.co.uk/itm/4-Channel-Bi-Directional-Logic-Level-Converter-3-3V-5V-Ardunio-ESP8266-etc-/142603531109?_trksid=p2349624.m46890.l49286

The DuPont connectors are just to connect to the board, you could just solder directly though.

Hope that helps!

Many thanks for your response. Which pump do you have. Do you think I can use your codes for mine. I have the 54112.

I have the 54154, I would take a guess that if it’s 4 pin it uses the same protocol though. I think there is some code commented out that will print whatever is received to serial if you have issues.

Thanks. Yes my pump is 4Pin. I will try this

Hello and thank you very much. Can I then simply use the received data for sending or do I have to convert them?

It runs im yerry happy.

Hello, I have ordered your plates. There I noticed that you are using D8. with D8 the ESP always restarts. I have now interrupted the conductor path from LV4 to D8 and put it on D2. And Change the Code. Everything is going great.

Thanks for your work.

A few level converters are on order from China, I'll try to build and test once they arrive. Thanks for the extra info!

Hi Mark,
My pump is the 54138, which is 4 pin as well. But I am not sure which pins to use. I have black, red yellow and green (starting from the arrow, pin1). I get 5V between pin 1 and 2 (black and red), and some pulses on pin 3 and 4 I presume since the multimeter value flashes slightly.
