SAt16sWiFi

Remote (Wi-Fi): on / off, 29 PWM channels in a sine wave 50-60Hz, integrated CNC

Turning on / off from a mobile phone, using Wi-Fi remote devices connected to the electrical assembly attached to this application and is an integral part of it. Without it, the application will not work. Because a special program is written for the microcontroller.

System Feature:

--------------------------------------------------

1. Turn on, turn off.

2. The ability to save settings for different devices, which are then selected as an option from a list in the application.

3. PWM for AC voltage, (the calculation was done for 50Hz, at 60Hz the adjustment step will be a little more than 1%, and at the minimum percentage settings the circuit will not turn on - for example, set the value to 2%, and a sinusoid cuts off the circuit earlier, because the sine wave is shorter in time, so the enable signal will never be output), the PD2 pin of the Atmega16 microcontroller is used with an input signal (high TTL level) when a sinusoid passes zero. When using a sinusoid - 29 independent PWM channels. Without the use of a sinusoid, 30 independent PWM channels.

4. The mobile application has a built-in numerical program control, which allows you to download the program texts for the CNC machine and display codes 4 signal lines for stepper motors. Circular interpolations (G2, G3) only along the XY axes, without simultaneously moving along the three axes: first move along the Z axis, then circular interpolation G2 or G3.

There can be 7 programmable stepper motors in total. In the application they have names: X, Y, Z, V, W, U, Q, these are arbitrary names, they may not correspond to possible standards.

It does not take into account cutting speeds and other various functions that can be indicated by the texts of programs for CNC machines, only the coordinates. Interpolation only with the coordinates of the center, without radius, it is calculated programmatically by I, J, the components of the program text.
