NI-845x v19.0.0 該軟件需要使用NI USB-8451和NI USB-8452 I2C和SPI接口
國家儀器團隊很高興地宣布NI-845X的可用性,該軟件需要使用NI USB-8451和NI USB-8452 I2C和SPI接口。

與NI-845X 18.0相比,對NI-845X軟件的19.0版進行了以下更改:


-新功能:增加了對LabVIEW 2019的支持。

-更改:刪除了對LabVIEW 2015的支持。

 The I²C/spi接口設備是用於集成電路( The I²C)或scsi並行接口(spi)設備的主接口或從接口。通過即插即用USB連接, The I²C/SPI接口設備是壹種便攜式解決方案,可與消費類電子產品和集成電路進行通信。與PCI接口相比, The I²C/SPI接口設備的物理位置更靠近 The I²C/SPI設備,從而減少了 The I²C總線長度並將噪音問題降至最低。 The I²C/SPI接口設備支持高達250 kHz的 The I²C速率和高達50 MHz的SPI速率,它還包括8條通用數字I/O線,用於各種應用,例如配置 The I²C設備的地址或切換LED。

NI-845x version 19.0.0 | 
The National Instruments team is pleased to announce the availability of NI-845x. This software is required to use the NI USB-8451 and NI USB-8452 I2C and SPI interfaces.

New Features and Changes from Previous Release

The following changes were made to version 19.0 of the NI-845x software compared to NI-845x 18.0: 
- New Feature: Added support for installation through NI Package Manager.
- New Feature: Added support for LabVIEW 2019.
- Change: Removed support for LabVIEW 2015.

The I²C/SPI Interface Device is a master or slave interface for inter-integrated circuit (I²C) or SCSI Parallel Interface (SPI) devices. With plug-and-play USB connectivity, the I²C/SPI Interface Device is a portable solution to communicate with consumer electronics and integrated circuits. The I²C/SPI Interface Device can be physically located more closely to I²C/SPI devices than PCI interfaces, reducing I²C bus length and minimizing noise problems. The I²C/SPI Interface Device supports I²C rates up to 250 kHz and SPI rates up to 50 MHz, and it also includes eight general-purpose digital I/O lines for a variety of applications, such as configuring the address of I²C devices or toggling LEDs.
