  1. Just a heads up. If you want a similar PIR sensor for cheaper, and it comes with a bonus case with 2AA holder and plenty of space ;P Radioshack sku 630-0282 Clearance item/Close Out price. The bigger Radioshacks have them, but have them search the sku in the district tool if not (the online one, not the POS one). Talking Pumpkin Insert. 97 cents. Same BISS0001 PIR controller, comparable PIR sensor (I opened one and checked). All smd caps/resistors, so it lies flat if you want to take it out of the case. Picked up three. At 1.03 each, I couldn't resist. Two will be left

  2. I had an idea that I might use for Halloween: Hide a device in the bushes near a walkway that uses a PIR sensor (still trying to find thos RS ones...). When triggered, run a cell phone vibrating motor attached to the bush to shake it slightly (at this point, assume someone looks that way). After a second or two, slowly (~2-3 sec) brighten two red LED "eyes" to look spooky. Then (optional), do a second or two of bright white LEDs in a strobe to really make them jump back. Bonus: Add some screechy sound with the strobe. Parts: MSP430 PIR sensor (or sub some other sensor) 2 red LED

  3. Remove all the externs as gatesphere suggested. Also LCD_data() is not declared nor defined. Those functions need to be resolved first.

  4. To me, the problem seems to be your heavy use of the "extern" keyword. It's un-needed in any of those files, but the file causing issues is lcd.h. The code (starting on line 70): extern void vWait( int uibaseinterval, int ucrounds); extern void LCD_init(void); void LCD_sendByte( char data); extern void LCD_inst( char data); extern void LCD_char( char data); extern void LCD_string(char const *point); extern void LCD_cursor( char data); extern void LCD_write_CGRAM( char CGR_addr,const char *CGR_data); extern void LCD_init_CGRAM(void); extern void LCD_disp_allpixels (void); I'd
