Introduce the waterproof and noise immunity of ML56 touch key. Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you the waterproof and noise immunity of ML56 touch key. First introduce the waterproof and noise immunity of ML56 touch key. Good waterproof function, support finger touch with 2 mm depth water droplet. IEC 61000-4-6 conducted noise immunity (CNI) with 10 Vrms noise voltage. Next, we will explain the related parameter settings of the ML56 touch key, and first explain the touch sensitivity. #Pulse Width (Touch key sensing pulse width time control) Touch key sensitivity can be adjusted by setting Pulse Width properly, shorter Pulse Width setting comes with poor sensitivity and less power-consumption, vice versa. Then explain the stability of touch performance, Part 1. #Times (Touch key sensing times control) Touch key raw data stability can be adjusted by setting Times properly, shorter Times setting comes with poor raw data stability and less power-consumption, vice versa. Stability of touch performance, Part 2. #IIR (IIR filter) IIR filter can control the ratio of current raw data and previous one. User can enable IIR Filter to be against noise. It will increase the touch response time when enables IIR Filter. Stability of touch performance, Part 3. #Debounce (Touch key debounce) Touch key stability can be adjusted by setting Debounce properly, the debounce times for touch key entry (on) and release (off) detection, shorter Debounce setting comes with faster touch response time, vice versa. Stability of touch performance, Part 4. #Trace Baseline (Baseline is generated by “Calibration”) Touch key auto environment compensation is an algorithm that baseline tracking each touch key automatically at power-up and keeps compensating environment variation affects touch key performance during runtime. Based on the above parameter description, the following introduces the waterproof and noise immunity parameter settings. The first is waterproof parameter setting. Good waterproof function, support finger touch with 2 mm depth water droplet. Touch key system parameters are shown in the table Pulse Width = 500 ns Times = 128 Next is the noise immunity parameter setting IEC 61000-4-6 conducted noise immunity (CNI) with 10 Vrms noise voltage. Touch key system parameters are shown in the table. Pulse Width = 2 us Times = 128 IIR New = 6, Old = 2 Debounce Entry = 1, Release = 1 Then we use the ML56 NuMaker Board to show you the waterproof function of the touch key. Dip the finger in water first, and then touch the touch key. Repeat the above actions, we can see that the touch key still works normally and is not affected. Finally, we use the ML56 NuMaker Board to show you the noise immunity ability of the touch key. Turn on the walkie-talkie first, and then interfere with the touch key at close range, we can see that the touch key still operate normally and is not affected. That's all for today's video, thank you everyone!
