Das Tester Click Board™ wird als Diagnosetool für die MikroBUS-Buchse verwendet. Es enthält eine Anordnung von 2 x 6 LEDs, die das Vorhandensein des HIGH/LOW-Logikpegels an jedem Pin signalisieren und dem Entwickler eine visuelle Rückmeldung geben. Zwei zusätzliche LEDs zeigen das Vorhandensein von +3,3 V und +5 V auf den MikroBUS-Stromschienen an. Dieses einfache Diagnosetool kann Stunden der Fehlersuche ersparen, da der Anwendungsentwickler nicht mehr verschiedene komplizierte Messinstrumente anschließen muss, nur um die Logikzustände an den spezifischen MikroBUS-Pins zu testen.
Each pin of the mikroBUS™ is routed to a red colored LED, which is protected by 1K resistor. This allows voltages up to VCC to be handled with no issues, providing a simple and clean solution for pin state testing. Once placed on the mikroBUS™ socket, no additional settings are required. There are no ICs or other active elements besides the LEDs. Its simplicity makes it very simple to use: as soon as it is connected, red and green power indication LEDs will signalize the presence of +3.3V and +5V on both the mikroBUS™ power rails. The rest of the LED array will be lit according to the state on the respective pin.
How Does The Tester Click board™ Work?
Development systems that utilize the mikroBUS™ socket, often require using of wire jumpers and/or connect the measuring equipment, routing the pin to another LED, or using some other workaround, in order to diagnose states on these pins. With the Tester Click board™, this task reduces to placing the Tester Click board™ onto the mikroBUS™ that needs to be tested, and LEDs will indicate if the state on the pin is HIGH or LOW with no additional hardware settings. This simplifies the troubleshooting greatly, potentially saving hours.
The Tester Click board™ itself consists of an array of 2x6 red colored LEDs, with their anodes connected each to the respective mikroBUS™ pin, via the 1K resistor. This resistor limits the current through the diode, allowing more than 5V to be handled with no problems. Each LED is clearly labelled the same as the pin it is connected to (e.g. PWM pin is routed to the LED labelled as PWM). Besides the 2x6 LED array, there are two additional LEDs, connected to the 3.3V and 5V power rails of the mikroBUS™, indicating presence of the VCC on both power rails. This simple design provides an easy, quick and simple tool to diagnose states of the mikroBUS™ pins.
To fully understand how to use the Tester Click board™, its best to get familiar with the mikroBUS™ concept, first. The mikroBUS™ is a standardized connector, used on most of MikroElektronika development systems. Among other things, it strictly defines the pinout of the connector, offering all the most commonly used interfaces: SPI, I2C, UART, PWM, analog input pin (AN) and few additional GPIO pins (chip select pin - CS, interrupt pin - INT, and reset pin - RST). Also, mikroBUS™ includes two power rails: 3.3V and 5V. This allows development of many different Click boards™ which can be freely exchanged between many different systems and platforms, without any hardware reworks or changes - the appropriate pins will always be at the same place on every system equipped with the mikroBUS™ socket.
Therefore, the Tester Click board™ can be used to verify the signal integrity of the tested mikroBUS™, especially while developing customized systems that include one or more mikroBUS™ sockets, or when developing custom applications. More information about the mikroBUS™ standard and its requirements can be found on the official mikroBUS™ page.
