====== Linia przerwania OS ======
====== OS interrupt line ======
Moduł KAmodLM75A został wyposażony w zworkę umożliwiającą dołączenie linii wyjścia przerwania OS (Overtemperature Shutdown) do złącza zgodnego ze standardem Pmod. Dzięki możliwości odłączenia linii przerwania układu KAmodLM75A od złącz Pmod, użytkownik nie musi przejmować się następstwami ewentualnych konfliktów wynikających z łączenia modułów modułów zgodnych z Pmod o różnych stanach logicznych.
The KAmodLM75A module is equipped with a jumper to connect the OS interrupt output line (Overtemperature Shutdown) to the connector compatible with the Pmod standard. Thanks to the ability to disconnect the KAmodLM75A interrupt line from the Pmod connectors, the user does not have to worry about the consequences of any conflicts arising from connecting modules compatible with Pmod with different logic states.
Wyjście OS służy do przerwania termicznego. Po włączeniu urządzenia wyjście jest najpierw aktywowane tylko wtedy, gdy temperatura przekracza wartość temperatury granicznej. Stan pozostaje aktywny dopóki nie zostanie zresetowany przez odczyt rejestru.
The OS output is for thermal interruption. After switching on the device, the output is only activated first if the temperature exceeds the limit temperature. The state remains active until it is reset by reading the register.

Description

KAmodLM75A is a module with NXP LM75A temperature sensor. The board is equipped with a Pmod I2C standard connector and a KAMAMI connector, allowing easy attachment of the module to development kits. Due to its small dimensions, the product can be used in many development projects, while the Pmod through connector allows the boards to be connected in series.

I2C bus lines

The KAmodLM75A module is equipped with jumpers enabling the connection of pull-up resistors to the VCC power pole to the I2C bus line. The jumpers give the possibility of independent enabled of the pull-up for the SDA and SCL lines.

OS interrupt line

The KAmodLM75A module is equipped with a jumper to connect the OS interrupt output line (Overtemperature Shutdown) to the connector compatible with the Pmod standard. Thanks to the ability to disconnect the KAmodLM75A interrupt line from the Pmod connectors, the user does not have to worry about the consequences of any conflicts arising from connecting modules compatible with Pmod with different logic states. The OS output is for thermal interruption. After switching on the device, the output is only activated first if the temperature exceeds the limit temperature. The state remains active until it is reset by reading the register.

Configuration of the I2C bus address

The KAmodLM75A module has the option of configuring the I2C bus address in the range from 0x48 to 0x4F. Configuration of the address is done by means of three jumpers located on the module board.
