Slim Node Si7021 sensor example
-
Folks, a word of caution, for people that are attempting this for the first time, please burn the bootloader before you solder everything, as silly me, I built the entire thing (without the si7021) and now I'll need to bin it because the ATMega is soldered to the board and I've no way to load the bootloader soldered to the board!
Ah, the life of a newbie :grin:
I think what I'll do is once I've actually got a working board, I'll do a newbie writeup so that people don't make the same mistakes as me.

@rsachoc Why don't you just solder some wires to pins you need ? The "in cicuit serial programming" concept would let you do it with almost anything attached.
-
Some of my tips (noob alert) that I've gathered in my travels so far for this temp Slim node
- Burn the bootloader onto the ATMega328 first! (here is a guide for Arduino as ISP)
- Check the capacitor polarity before you solder it (the 4.7uF electrolytic capacitor, the others don't matter)
- I prefer using strips for the Atmega (see here) as you'll have more clearance for the capacitors which sit underneath (there is a caveat to this however, in that if you're not sure if you've got/burnt a bootloader onto the ATMega, using strips there is no going back, whereas with the chip socket, you can remove the ATMega). Update I think, for me anyway, if you're confident that the ATMega has been bootloaded successfully, I still prefer strips, however if you're unsure what you can do is use the socket and just sit it higher in it's position to get a decent clearance.
- The bill of materials (BOM) is here and also helps with figuring out which pieces go where
- Solder the capacitors, wires for Si7021 (with si7021 attached) and FTDI pins to the board first, then the strips + AtMega328p (see below), then the NRF last to the board. I found that the FTDI pins facing straight up were best for the box I was going to put it in
- Solder the strips to the ATMega first, then to the board
- Check the size of the box/fitting you are going to mount this in before you do all the above!
- Check that you are putting the ATMega chip the right way on the board, the notch should be facing the pins for the FTDI.
- Check continuity of the pins from the ATMega to the board pins underneath, I found the ATMega to strips were the most difficult to solder, and after I tested continuity I found a single pin which didn't have connection, so I added some more solder to this pin.
- Don't forget the resistor at R1 (I soldered this to the underside of the board, less by choice and more by the fact that I forgot about it, but I guess the preference would be the same side as the capacitors)
- I strongly advise buying the 3.3v ready si7021 temp sensor (here) as the modification to the 5v version is quite difficult for a newbie (the components are quite small) and you'll probably mess it up like I did.
General soldering tips
12) Practice soldering first, some of the joins are a little challenging and it took me a few attempts to get the hang of it
13) Get a decent size tip, my first was a bit large -

Thanks all, I'm sure I will be adding to it, as I'm now trying to compile and upload the sketch. However, I'm getting the following error:
#error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless. ^ exit status 1 Error compiling.I'm using the W5100 MQTT gateway sketch (which I believe is on the development branch), so I'm not sure if that's what's causing the error? I've tried deleting the Arduino IDE, the mysensors development branch from my PC, and reinstalling and redownloading the mysensors dev branch, but the same thing happens?
-
OK, so it seems that it was because I was using the dev branch that I'm getting that error. I switched over to stable and the sketch compiles, although I do get a warning.
WARNING: Category '' in library UIPEthernet is not valid. Setting to 'Uncategorized'But I also can't upload the sketch above:
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x18I noted above that something needed to be changed in terms of the baud rate, mine is set at 115200 in myconfig.h and I can't seem to find a reference in mysensor.h

@rsachoc I sorry, but there seems to be an error in the sketch in the first post. Baud rate should be 9600 everywhere if you use the common Slim Node fuses and bootloader. Upload (board.txt), MyConfig.h (not MySensor.h since v1.5), Debug-prints and Arduino IDE serial monitor.
-
Thanks, I've updated the sketch that I downloaded, also myconfig.h so that should be good. What do I need to select in the Arduino IDE for board type? I searched in the slim node thread and didn't see a reference to any changes?
-
Hmmm ok, that's what I thought...still no luck, I've modified the boards.txt with the text from the slim node thread, and now it still has the same error message.
To confirm, my FTDI adaptor is attached to the board pins as follows:
FTDI <-> board
GND <-> first pin (i.e bottom left of board when looking at board laying long side horizontal and NRF radio on the other side)
CTS <-> board marked GND
PWR <-> board marked VCC
TXO <-> next up i.e. 4th pin
RXI <-> next up i.e. 5th pin
DTR <-> next up i.e. last pinOther than that, I guess it may be something wrong with the way I made the board? If so, what's the best way to troubleshoot? Could it be a bad bootloader flash? Is there a way to check if the ATMega has a bootloader?
edit in fact, it could be because I don't have the Si7021 connected? Could this be the reason a sketch is not uploading successfully? :worried:

Thanks, I haven't actually built a new node, but have been double checking everything on my current node. One thing I wanted to confirm, the 4.7uf capacitor, does the negative leg have to be on the corner of the board, as this is the way I have it currently? I think looking at the board layout in the main slim node thread, it should be the positive leg on the corner and the negative leg on the side of the board (the short side of the board)?

-
Ok so that may be the problem then! Let me solder it the right way and see if that helps otherwise I'm going to create a bare bones slim mode as suggested
edit to confirm the positive leg of the capacitor goes to the positive marked plus sign hole on the board?
-
OK so I changed the polarity of the 4.7uf capacitor and I'm still receiving the same error. So I built a barebones one without sensor and without NRF. I am still getting the same error when uploading the sketch via the FTDI adaptor. I tried uploading a sketch to a Sensebender I have and it worked fine, so that rules out the FTDI adaptor.

So I can only think that it must be related to the ATMega bootloader? In the how to burn a bootloader thread, I received the following when trying to burn the bootloader, so I assumed it uploaded correctly?

@m26872 well that is probably it! I didn't even realise I needed that, oops! Sorry :disappointed: ! Let me try and get one (I think I have some already) and get soldering
It lives! Well the one node I created does at least! I'll troubleshoot it, but the problem was the R1 resistor, which I (noobishly) forgot about! But very pleased, and thanks to m26872 especially and everyone else who helped.
I've updated the lessons learn post too!
