Dear all,
here below a first update, the demo board that will be used to perform the test.
Into the bottom of the image, into the separate small bread board, there is the CAN bus.
Into the big bread board you can see on the top the two slave node and into the bottom left the RS232/CAN converter...
Thank you bzznxlad.
I've written some time ago a code using the Microchip USB stack, this is a very simple task, just fill the processio function and the work is done, I've used the PICDEM FS USB demo board and to do it I've simply changed few line of code to adapt the code to my application...
Thank you bzznxlad for your question, in the final release the bridge will be changed in order to act as a USB to CAN converter, but for starting this is not the main focus of the design. Anyway we need to use a bridge from PC and the CAN network and for this reason I've decided to start with...
Intro
Hi all,
is now long time from writing the last tutorial on this great forum, now is time to start again with, I think, an interesting thematic about CAN bus network with PIC18F4680 microcontroller. This is a step-by-step design because I'm just starting now with this argument, the time...
Now I've loaded the design into the VB2008 Express edition (v9.0.30729.1 SP, .NET framework 3.5 SP1), when the IDE start I've a series of error, some related missing resource and some regarding some missing files Application.Designer.vb, AssemblyInfo.vb, Resources.Designer.vb...
Thanks but I've some trouble in downloading the source, could you check please? After pressing the download button a nag screen arise and after the time countdown expire there is no link for download.
Thanks

I've revised the component identification because the inductor connector from the anode of the output diode and ground have a footprint with just two pad then it seems more likely a single inductor than a coupled one.
Following this I've thinked a new disposal reported into the attached image...
Dear FvM,
yes I know that because the output should be high or below the input voltage and also because the original module claim it a s a SEPIC but I've did some search also into this direction without found anything with same package and input voltage range, the only chip that seems to meet...
Dear All,
after some surfing may be I've found the IC, actually it's seems close to the SEMTECH model SC4502:
https://www.semtech.com/images/datasheet/sc4502.pdf
If we set a 0.6 V hysteresis for the shutdown circuitry, by using the (11) at page 11 we obtain:
R3=VHYS/IHYS=0.6/4.6uA=130434.78...
What IC inside this integrated module?
Dear all,
I'd like to ask if someone know what type of switching controller was used inside this integrated module (SEPIC topology, 1.5 MHz switching frequency), here below the general specification:
Min. input voltage: 1.5 V
Max. input voltage: 16 V...
The question issued is very important regarding the power supply stability, I think you can also take a look into the National Semiconductor web site at this address:
**broken link removed**
on the right you can fill the form with your design data in order to have some help into the device...
Hi all,
for a my battery powered application I'm using the Easy-Radio ER400TRS 433MHz Transceiver from Low Power Radio Solution:
**broken link removed**
this module works nice but I've a drawback due to the quiescent current when the module is into the read mode (listening) equal to 20 mA...
Yes, sorry, I've see only now that the scanned was did from you and not from huzuhong525. During my writing I've not noticed that the post author and the author of the scanned image was different.
Thanks to point it.
Best regards
Pow
In your schematic you use two P-Channel MOSFET, the complementary action is achieved by means the NPN transistor Q3, just to point because into the previous reply you said use two MOSFET P&N instead here is two P MOSFET.
Thanks.
Bye
Pow
