Hi, I have attached the code files for the UV Exposure unit as text files. They were produced in JAL and must be given the file extension of .jal to work.  JAL itself is free to download but if you want to use this code in MPLABX for example, you would have to modify it to suit. You must include the file named 16f877a_inc if you use JAL. This is not my work, it is a fairly standard library file which looks like it has been modified by various programmers and can be found on the internet. The equivalent library file for the compiler would have to be found too if you want to use a different system. I hope this all works for you, I use the exposure unit quite regularly and find the timer with buzzer very useful as I can safely do other things during the exposure. Regards Steve

after downloading the boot and connect the board to an USB port..... .... the device descriptor is well initialized by windows. before that I swap by wires D+ and D- on the board because connecting D+ to DM is a bad idea... and I did it (so seally am I!) so first issue : on the schematics please note that D+ and D- must be permuted! sorry!

I ordered the Atmel kit because the project arouse my curiosity ... well presented, functional, original and, it seems, scalable! I find the prototyping Elektor board (i have to say beautifully finished) a little bit "big" for this kit, which wants to be miniature and I think the wiring, even it is not monstrous, would be simplified by etching a circuit a bit more suitable (less wiring) and smaller. The sound is good. But it seems to me that the bass boost is enabled by default. Too bad, it is not possible to disengage it from the menu. Less good is the MONO output. No success to get a stereo decoding even when trying many directions with the audio cable, so: - Is it a lack of sensitivity? - Is this a problem of pre-emphasis? - Is it a software implementation ? Perhaps connecting a real antenna would solve the problem, but I have not tested yet, assembly is still recent ! To make that will i have to tweak the little FM card by removing the L4 / C4 and connect the antenna to the RDA5870's pin 2 ? If not, has anyone a different idea / suggestion? Otherwise, I don't know at all how to verify the inclusion of mono or stereo setting in the  μC code... ! :-( If someone encounters the same problems, thank you for your feedback... that would be great Thanks a lot !

I finally find another bootloader from microchip which comes with a long list of #pragma directive for configuring the clocking gear. I will test it this afternoon

What has happened to this siphon meter project? I can't seem to find any detailed description of its design.
