Re: Power supply for Wemos r32 cnc v3 + ds3231 +WeMos D1

Good news. I have old Hp laptop 19v and a step down dc. Just need some modifications. Today received Chinese 12v ac-dc adapter , but it burned once I switched ON the switch. Luckily my Onstep still good. 

Thanks.

Yes, if it will actually meet those specifications. All the Chinese power bricks like that I have bought have turned out to be worthless.

Hi,

Just want to know can we use 12v 5A ac-dc adapter to power up the onstep? Currently I use 12v litium - ion.

Thank you.

Yes, 19v laptop supplies are also very popular, but you'd then need a buck converter to lower the voltage for the esp32 - need 12v or less.

The bucks are very cheap.

Thanks Hendrik for your testing and reporting.

I did some more testing with the new version M. Guiding seems to work fine now while nina is active and doing things, did not have any more weird issues of runaways when starting guiding, i however have another issue now where the 3 point polar alignment routine does not slew fast anymore (the nina plugin), it seems to use the guide rate to slew from that plugin now. This worked fine with the E version of the firmware (but if i used it with E this would also mess up the guide rate). But slewing in Nina to a target seems to work fine. 

I would be interested to know if there is any way to see the current guide rate the driver is on? Could this be added to the onstep ascom driver screen for example or the web interface? That way it is way easyer to spot what is going on.

Re: SHC with 2.42 display

Patrizio Boschi <patrizio.boschi@...>
 

Hi, I'm trying the 2.42" display (blue one).
Did the R8 / R10 / R11 solderings, connected DC to GND, connected Reset to GPIO16, but now I have this problem... last column is displayed on first columns. Example sketches from Adafruit SSD1306 works perfectly.


Re: Pull up resistors on SHC buttons?

Patrizio Boschi <patrizio.boschi@...>
 

After checking, also pin 2 doesn't have pull-up.

So i ended using pins 15, 4, 12, 18 (the latter is available because I don't use the second RJ12 port) instead of 34, 35, 39, 39, and NO external pull-up resistors.

Maybe some help for you. I have also just "Velcrowed" the Mini on the bottom of the Wemos
with directly soldered connections.

Sadly the previous cable might have only been meant to provide power.  It's not necessarily bad.  I was the problem apparently.  Sorry for that and appreciate the help.

It may have been a "Power Only" cable.

It seems it was a bad cable.  Switched it out and in business apparently.


Re: Flashing MaxESP3 #maxesp3

Alan Tarica
 

OK that is what I'm using.  The board is connected to the computer via the usb.  

I've verified I can connect to the board via WiFi.


Re: Flashing MaxESP3 #maxesp3

No, we are talking about the micro-usb port on the end of the ESP32 processor chip. You need a data USB cable to connect between there and your computer. USB is a kind of Serial port.


Re: Flashing MaxESP3 #maxesp3

Alan Tarica
 

Are we actually talking about having to use the RS-232 port?


Re: Flashing MaxESP3 #maxesp3

Drew 🔭📷🚴‍♂️
 

"Port" is greyed out. Do you have the ESP32 chip connected to your computer?


Re: Flashing MaxESP3 #maxesp3

Alan Tarica
 

Still don't think I'm understanding what I'm doing wrong.  Even updated to 1.8.16.


Re: Flashing MaxESP3 #maxesp3

Drew 🔭📷🚴‍♂️
 

How about this: https://www.arduino.cc/en/software

That version should be OK. Connect your ESP32 module with a data USB cable. The "Port" option should now have the serial port you will program over. To verify that you have selected the correct port select "Get board info". If you get a response you have found it.

Now you can select "Upload" and the firmware will transfer to your board.

Got 1.8.15 assuming good enough.  

So thanks.  Still confused about the port.  Assuming I did things correctly.

First install the stable 1.8.16 version of the Arduino IDE. The 2.0.0 beta version is not recommended for OnStep at this point. Set it up per Tom's instructions. Then we can address the serial port issue.
