[12:23:48] <sebus> Hello there
[12:28:08] <sebus> I need to make -12V rail @200-300mA from 15V DC. Someone can suggest any chip with /enable signal or something?
[12:42:45] <Lambda_Aurigae> sebus, sounds like a job for a boost converter to me.
[12:43:16] <Lambda_Aurigae> chip by itself isn't gonna do that...maybe a small switch mode boost converter though.
[12:43:37] <Lambda_Aurigae> if you only needed 5mA or so you could do it with a max232.
[12:43:38] <sebus> Lambda_Aurigae i am just full of L5972's
[12:44:00] <sebus> but they don't work almost at all in that conf.
[12:44:18] <sebus> LM2574? geez, huge inductor
[12:44:28] <sebus> 34063 is even worse.
[12:44:53] <Lambda_Aurigae> to get that kind of current you will need a decent inductor and at least 2 capacitors I think.
[12:47:17] <cubeast> Hey, any suggestions for a generic UART/serial C library? (atmega328p)
[12:47:30] <cubeast> and atmel studio
[12:51:15] <Lambda_Aurigae> http://homepage.hispeed.ch/peterfleury/avr-software.html
[12:51:41] <Lambda_Aurigae> as for atmel studio, no clue.
[12:51:47] <Lambda_Aurigae> it doesn't run on linux so I can't run it here.
[12:53:33] <cubeast> it uses avr-gcc, so the code should probably work
[12:53:44] <Lambda_Aurigae> it is somewhat older, however.
[12:53:47] <Lambda_Aurigae> I still use it.
[12:53:53] <Lambda_Aurigae> have used it for years here and there.
[12:53:59] <Lambda_Aurigae> and heavily modded it for my purposes.
[13:27:02] <Jartza> cubeast:
https://github.com/andygock/avr-uart
[13:27:16] <Jartza> that's updated version of peter fleury's lib
[13:27:30] <Jartza> but compiles nicely with latest gcc too
