OK, here are the results of the "blink a led" test(you won't be happy...)
When declaring "pragma target clock 8_000_000" and "pragma target OSC INTOSC_NOCLKOUT", and : * not setting OSCCON_IRCF, the LED blinks @1Hz (I swear) * OSCCON_IRCF = 7, the LED also blinks @1Hz * OSCON_IRCF = 0, the LED blinks @ ..... I don't know, it's so slooooowwww.... but setting "pragma target clock 31_250" gives a 1Hz blinking LED, as expected according to the datasheet (also tested OSCON_IRCF = 1 with clock 115_000, blinks @ 1Hz as expected too) What about i2c ? I've tried setting OSCCON_IRCF = 7, as you suggested, and... it does not work (as expected I'd say). Reading the datasheet, it's said the INTOSC source is a 8MHz clock (something like that), and there are postscalers, selected with IRCF. Question now is why IRCF = 7 by default where the datasheet says it's 0. (not sure this is good test, but serial_hw_write(OSSCON) give "|", 124 decimal, 1111100 binary (IRCF = 111 = 7). IRCF = 0 might be the default only for INTRC, not INTOSC... Seb Le Monday 22 December 2008 17:55:51 Joep Suijs, vous avez écrit : > 2008/12/22, Sebastien Lelong <[email protected]>: > > Wow...
