Combination of CMOS-LCD display

: L ugly 2RC select R, C values are 100 ~ 800Hz oscillation pulses generated by the circuit within the plastic after 50 ~ 400H. z 50% duty cycle square wave signal III,[link widoczny dla zalogowanych], LCL104 features and functionality LCL104 is 2 ~ l0 into radio hosting, decoding, driving a few CD portfolio display (with BCD code output). Shape as shown in Figure 1 Figure 13 pinout. Figure 14 is a logic diagram. Figure 14 in addition to the same LCL103 outside, QQ, VDDE four qqQcQ. J3 ‰ LELEDPILCL】 CRLERBIRBODPICOM Figure 04 Figure I4Q, Q. Output BCD code information that can be used for data recording and processing. LCL104 counting function in Table 3,[link widoczny dla zalogowanych], the control function shown in Table l, electrical parameters in Table 2. Counting function waveform in Figure 12. 9 ∞ ● ● ● ● 16】 A ffJl a picture of a 5LCL104 use,[link widoczny dla zalogowanych], required an external oscillator square wave can be achieved, as shown in Figure 15. AC square wave by the non-door F ... F, resistance and,, electric kiln c RC oscillator circuit composed of production, divided by the D flip-flop is 50 ~ 400Hz signal frequency, such as the duty cycle greater than 50% of the excess,[link widoczny dla zalogowanych], it is good Add a shaping circuit. Fourth, CMOS-LCD of the typical application diagram I6DPI, port 1. Number of counts carry a number of cascade connection figures in the count, the count signal to the lowest level of the CP side. Rounded to the higher by the E-bit input side. DPI received the decimal point positioning. Lit decimal point, not the decimal point display DPI received the decimal point out. When CR termination count, then. When cleared. Figure 16 (see previous page) for the multi-digit counting rhyme LCL103 connection method. 2. Invalid connection number zero blanking count connection, to achieve high void zero blanking the RBI as long as the highest O-level access logic, and to all levels of the RBO's RBI received low end of its adjacent to the minimum RBO bit vacant. RBI received the highest bit high, you can not achieve zero blanking invalid, shown in Figure 163. Reversible counting shows clamor for the addition of both if you want to count the counter can count as a subtraction, as long as the use of LC \CL # Count input side lose, the other count input connected to the high end of CLD wife; for subtraction counting, counting pulses from the CLD side lose, CLg have to take to the high end. CCA0192 the Q,[link widoczny dla zalogowanych], Q, QQ four output termination to LCL003 the A, B, C, D four input side, as shown in Figure 17. r Ning bream fat) (Continued from page 17) values are amplified in the external RAM expansion, input and output data are expressed as a six-byte floating point. V. Conclusion In overall design, the full use of an 8098 microcontroller, to determine hardware and software programming associated with an optimal combination. In all of the features needed to meet based on the instrument, but also access to the most good performance / price ratio, so that the overall structure simple, compact and lightweight machine has become the instrument of measurement and related products in the province, test departments, and distortion measurement range of 0.1 to 5%: 4-5% accuracy ( reading) 4-1 words (distortion) 1%; 4-10% (reading) 4-1 words (distortion ≤ 1%). On this basis, the instrument can be used as impetus for further expansion of harmonic analysis systems, such as together with the corresponding sensors, but also as a variety of rotating machinery failure analysis equipment.
