.. Atmel ATtiny2313 ) controller. The RDS data is displayed on an 2 x 16 character LCD. It shows program service name, RDS clock, TA flag status and scrolling 64 characters long radio text. The decoder needs an Stereo multiplex signal as ...
.. pad currently selected. These LED's are connected to a decade counter, which sequences the LED's when it receives a clock pulse.Only one LED can be lit at a time from the decade counter, so although this circuit contains many ...
.. up to 61(H) x 32(V) dots and they drive half of the LCD panel each. SG12232C requires a 2 kHz square wave as LCD drive clock and it must be supplied during power is on or the LCD panel may be damaged due to static bias. The bus ...
.. fun time putting this particular project together, and I hope you do too. This project shows how to build a talking clock with time temperature display + it includes several handy C functions you may find useful for other embedded ...
.. was purely analog and had no “10-MHz reference input” on the back to allow it to be synchronized with the ADC clock. The result is substantial spectral leakage in the FFT, so that it looks more like a circus tent than a single ...
.. for other system triggering. The half-duty-cycle generator fits into a CPLD, such as an Altera EPM570 with a 60-MHz system clock and an MM74HCT244 buffer to output a TTL signal. Listing 1 contains the program for the CPLD .
.. To light N segments of a display that is M segments long, the first output port sends M N pulses to the shift register's clock input. This design lends itself well to situations in which unused I/O-port lines are at a premium, as is the ...
.. voltage results. To ensure that one of the detectors holds the highest peak value for the entire input period, the reset clock period is slightly longer than one-half the period of the lowest input frequency. Figure 2 illustrates typical ...
.. and distance traveled, and displays the results on the LCD. One of IC1's internal timers, Timer0, increments after every N clock pulses. Distance traveled equals 2πR, where R is the wheel's radius. To calculate speed, IC1 divides the ...
.. The routine seen in the code is called a 'Bit Banging' procedure. 'Bit Banging' is when you simulate the clock through your own digital device to get the given input. A standard SPI could have been used with much more ...
