Hi All, I´am ARM noob and I need help... (noob! previously some experience's with AVR-8b (only), self-multi-graphical/BW aps´ w 1-W/I2C/485/RTC/COM/.../other..., only as hobbyst-enthusiastics :D - not for commerce use)
So, 1 year ago I bought some PCB´s with ARM uC for my "selfeducation" - uC LPC2366. Yesterday I received ULINK-2 programmer. IDE Keil 5.xx 'free' was successfuly tested. My first program (debug) "LED_blink" - all OK - as in AVR... I discovered on web example project called 'HID-USB' with LCD "driver" (like hd44780).
HELP: Anybody know what menas:
Commented: /* PINS: Yea... all is in datasheet :D - DB4 = P1.24 - DB5 = P1.25 - DB6 = P1.26 - DB7 = P1.27 - E = P1.31 (for V1 P1.30) - RW = P1.29 - RS = P1.28 */ */ Wtf ??? Definitions: //#define MCB2300_V1 /* First version of MCB2300 */ #define PIN_E 0x30000000 #define PIN_RW 0x20000000 #define PIN_RS 0x10000000 #define PINS_CTRL 0xB0000000 #define PINS_DATA 0x0F000000
Anybody know 'THE math' formula for recalculation "RW = P1.29" -> to "0x20000000" ??? I tryed do some calculation on paper, hex / bcd / real conversion :) but no success...
Thansk for all replies... I think, that many people trying find same answers...
Thx, port/pin P1[16] = 2^16 = 65536dec = 10000hex = 0x00010000
