Digital Proportional Controller TX8 ATS308T/RX8 ATS308T/RX8 ATS308R ATS308R Detailed Description and Application notes (1) Analog Channel Inputs of TX8 ATS308T ATS308T TX8 ATS308T ATS308T provides two independent analog channels (Ch1 and Ch2) and two offset adjustment inputs (Offset1 and Offset2) for every analog channel. There are 28 usable steps totally for each channel besides 4 steps dead band, and 14 steps on both sides of dead band of course. Considering the offset adjustment of two analog channels, Offset1 (for Ch1) and Offset2 (For Ch2) inputs are provided for moving the channel input voltage range of CH1 and CH2 up and down whole, thereby inputs being in the dead band. The usage of OFFSET adjustment function is selectable. The input voltage of OFFSET should be set to 1/2 Vref by placing two resistors whose value is equal, if unused Notice that the analog channel input range absolutely meet the requirements of voltage that is generated by variable resistor (2.7V reference is used). The resistor's Total-RotationAngle is 220 °, its value is 5 K , and its effective input range must be above 50°. If the input rotation angle is less than 50°, some steps should be losing. How to resolve the problem? Using external higher reference Voltage is a good way. (2) SO and SC output signals of TX8 ATS308T ATS308T SO is the base band signal that is used for wireless application. SC is the signal that has be modulated by somewhat carrier signal. Notice that the carrier signal frequency is half of oscillator's frequency. In the IR application, the different carrier frequency can be set throughout the changing the oscillator's resistor. (3) MOD function of TX8 ATS308T ATS308T TX8 ATS308T ATS308T particularly provides the MOD function for the designs that realize the car's motorial form by controlling tank (4WD)'s motions through the RC car (2WD)'s handles (one for driving Speed, another for steering servo) (4) Function Outputs of RX8 ATS308R ATS308R corresponding to TX8 ATS308T ATS308T's analog channel inputs When the signal come into the SI input that is from amplifies and RF circuit, RX8 ATS308R ATS308R will decode the encoded signal, and produce the corresponding outputs. As the input voltage of Ch1 or Ch2 is equal or above than 1.7V, M1N or M2N will be High Logic and M1 or M2 will hold Low Logic Level. Also as the input voltage of Ch1 or Ch2 is equal or less than 1.0V, M1 or M2 will be High Logic and M1N or M2N will hold Low Logic Level. In others input situations of TX8 ATS308T ATS308T, the duty ratio of PWM signal will change linearly. PWM signal period is 8ms(when oscillator's frequency is 128KHz), and the first step's duty is 12.5%, then increase 6.25% ratio step by step, until High Logic. Of course one output is active when another match inactive (Low logic). The first Step: 12.5% duty 1ms 1ms 8ms 1ms 8ms (5) Steering System (with VR feedback) of RX8 ATS308R ATS308R Version1. 00 - 10 - May 15, 2004 Actions Semiconductor Co., Ltd. Digital Proportional Controller TX8 ATS308T/RX8 ATS308T/RX8 ATS308R ATS308R VR is critical for the controlling of steering servo. Just like driving a car, people know how many steering wheel angles should be rotated depending on eyes. The feedback of eyes must be necessary. In the steering servo applications, how to insure the rotation angles lies on outsides feedback. That is VR feedback. The outputs (LEFT and RIGHT) of chip drive the motor by the driving circuit, then the rotation of motor affects one DC level, and the DC level's feedback to the chip makes the chip changing the outputs to what the CHANNEL wanted after signal processing. Relation between chip outputs and VR feedback voltage is indirect. DC motor and geardown mechanical architecture play an important role. Figure blow shows this close relation. Motor's rotation Changing of VR DC level From TX8 ATS308T ATS308T's Control Driving Outputs of CHIP(Left Right) Steering motions Changing of variable Resistor From the figure above, it is easy to find that the dead band of VR input can move from one position to another position. When TX8 ATS308T ATS308T's Ch2 analog input is in the dead band, then adjust the input voltage of VR pin until there is no any active outputs of LEFT and RIGHT, and just now a measurement of VR input voltage shows that voltage is about 1.35V(two steps' dead band) (actual voltage range depending on actual device `s reference voltage). Notice that the analog channel input range absolutely meet the requirements of voltage that is generated by variable resistor (2.7V reference is used). The resistor's Total-RotationAngle is 220 °, its value is 5 K , and its effective input range must be above 50°. If the input rotation angle is less than 50°, some steps should be losing. How to resolve the problem? Using external higher reference Voltage is a good way. (6)Adjustment Oscillator for TX8 ATS308T ATS308T's Ch2 input Adjustment oscillator is used in the regulating of the outputs (M2, M2N, LEFT, RIGHT) corresponding to the Ch2 analog Channel input. When the frequency of Main oscillator is equal to the adjustment oscillator's, all the outputs about CH2 is just like what the forth descriptions above say. If the value of adjustment oscillator's frequency is changed, all the outputs' PWM signal duty ratio will vary linearly up and down Adjustment function about CH2 is very important for the designs. For example, different value of the first step's duty for driving the steering servo is needed because of different mechanical architecture and motor characteristics of different types of steering motors. So the best steering servo characteristics can be realized by adjusting suitable value of oscillator of adjustment. Version1. 00 - 11 - May 15, 2004 Actions Semiconductor Co., Ltd.
