This window lets you test the physical output ports directly, bypassing all of the software layers used for the logical ports. This is useful for determining whether a problem with a device is coming from the hardware or somewhere in the software. If a port fails to work correctly in this mode, the problem must lie in either the physical hardware, or in the device-level Pinscape software or configuration setup.
The separate Logical Output Port Tester window lets you view and test the software ports that DOF and other game programs on the PC access. DOF can't access the hardware ports you see here directly; it goes through the logical ports. Your JSON configuration determines how the logical ports relate to the physical device outputs.
Warning! Flipper Logic timers are disabled when this view is active. Exercise caution with devices that could overheat if activated for long intervals, since the normal protective timers can't intervene in this mode. When you activate a device port in this mode, it will remain activated until you manually turn it back off.
This mode shows a list of all of the physical output devices, with a slider control for each port that's enabled as an output.
The window shows the Pico's own GPIO ports, plus all of the external peripheral chips that you've configured that can act as output devices. This includes PWM controller chips (TLC5940, TLC59116, PCA9685), shift register chips (74HC595), and GPIO port extender chips (PCA9555).
Each Pico GPIO pin and each peripheral chip output pin is shown with a slider control. You can use the sliders to control the current output level on each port, to test its effect on any attached devices. The sliders use the native PWM range for the chip. Some PWM chips have 8-bit ranges (0-255), and some have 12-bit ranges (0-4095). Non-PWM chips that can only act as simple on/off switches still present as slider controls, but the range is just 0 to 1, corresponding to OFF and ON.
All of the controls in this view are direct hardware controls. None of the logical output port modifiers apply, since this view bypasses all of that. No time limiters are applied, nor are features like gamma correction or active high/low polarity inversions.
Some types of devices have bidirectional ports, meaning that the ports can be individually configured as inputs or outputs. That includes the Pico's GPIO ports as well as ports on GPIO extender chips, such as PCA9555. The window shows ports for all of the devices that are capable of being assigned as logical output ports, but ports that aren't actually used as outputs will be shown as disabled.
Pico GPIO ports are only enabled in this view when they're assigned to logical output ports in the configuration. This avoids accidentally interfering with GPIO ports that are used for other purposes, such as for logic signal connections to peripheral chips.
