enormous binary number, to divide it by another fixed binary number, and to make the remainder from this division the checksum. Upon receipt of the message, the receiver can perform the same division and compare the remainder with the "checksum" (transmitted remainder). Example: Suppose the the message consisted of the two bytes (6,23) as
// In other words, don't go hacking around and reading from the rtc_bcd[] buffer directly, unless you want the raw BCD results. // Cumulative number of days elapsed at the start of each month, assuming a normal (non-leap) year.

Hardware The hardware design for using Ripple Counters (also called Ripple Carry Binary Counters) is straightforward. The Ripple Counter requires a ripple input (AI) and a reset pin (AR). Both pins are used together by the application to control addressing. The AI pin increments the address (sequentially) and AR resets it to zero.
• Download the binary machine code to 32UC3A through USB USER port. Some common problems and workarounds are included as well. ONLY WINDOWS XP PROFESSIONAL 32 IS TESTED. The following thread is used when preparing the tutorial. You may take a look at it before start to obtain a big picture.
