02:54.30joe_bleauAnyone ever use the Cui V7803-500?  It's a SMPS drop in replacement for the 78xx series linear regulators.

03:13.34MonMothajoe_bleau: I have not.  Sounds interesting, though.
03:13.45MonMothathey crammed all the passives into a TO-220 size case?
03:16.38MonMothahum, looks a little bigger, but no too much
03:17.30MonMothanot cheap, though
03:44.28MonMothajoe_bleau: any further word on that project, btw?  I know you said some stuff might happen early this week.
04:03.07joe_bleauActually, I thought I said some discussions would take place this week.
04:03.11joe_bleauAnd they will/have.
04:03.24joe_bleauThe customer won't commit without seeing some sort of demo.
04:03.36joe_bleauWaiting to hear on LCD sample availability.
04:03.52joe_bleauSo, we're still in a holding pattern.
04:08.01joe_bleauI'm hoping the Cui part will get me out of a bind.
04:08.25joe_bleauNeed ~300mA at 3V, but my 7V supply isn't happy with more than 200mA.
04:08.42joe_bleauAnd I only need a handful, so this looks like a quick-n-dirty option.
04:09.25joe_bleau4 layer quick turn boards will make the SMPS pricing nothing but noise on the bottom line.
04:20.49MonMothajoe_bleau: ah yeah, those look to be perfect for that
04:21.59MonMothalow volume 4 layer quick turn PCBs tend to dominate the cost of tihngs

19:30.50piglithello i am looking for a open source C compiler for cortex M3 can anyone please point me in the right direction?
19:34.42wmatpiglit: doesn't GCC work?
19:37.06piglitwmat: well i did avr gcc on a atmega48 atmega88 and a atmega16 but now i am looking for a more advanced microcontroller with more of everything like 12 bits adc faster etc. and i do not know what works the Xmega is pretty new, and the cortex M3 looks very promising
19:41.27*** join/#edev likewise (n=likewise@atwork-193.r-212.178.107.atwork.nl)
19:43.51wmati'm fairly certain Cortex M3 is supported by GCC
19:44.09wmatif not, try CodeSourcery's toolchains
19:48.59HcEpiglit: I can recommend Xmega's and AVR32 UC3's 0:)
19:49.17HcEpiglit: Xmega is supported by GCC, not optimal yet, but it works
19:49.40piglitHcE and the reason that you advice Xmega is?
19:51.45HcEpiglit: I'm biased :) I work with AVR and AVR32
19:52.04HcEit really depends on what you want to do
19:52.41HcEXmegas consume very little power, have DMA, event system, ADC, DAC
19:54.59piglitHcE i want to build dataloggers (at least 12 bits adc) use network and usb and not have to learn 10 different microcontrollers i did atmega48 88 and 16 avr gcc and 12f683 asm 16f870 16f876 16f88
19:59.38HcEpiglit: then I would take a look at UC3A1, or UC3A3 if you need high-speed USB. They both have an Ethernet MAC. Hmm, but only 10-bit ADC :/
20:00.29piglithttp://www.st.com/mcu/inchtml-pages-stm32.html    <--- these look nice
20:00.39piglit2 12 bits adc
20:00.41piglitetc
20:02.00HcElooks smooth
