Low Pin Count, or LPC, was introduced by Intel in 1998 as an interface to connect low-bandwidth devices to the CPU. It had replaced its Industry Standard Architecture (ISA) counterpart improving the data rate transfer from 8 MHz up to 33 MHz. LPC transfers data using a 4-bit bus and features an architecture usi...

Question from the Customer:
Out test results show a repeated error while programming M95128-R EEPROMs. The EEPROMs are located on separate panels. To program these SPI devices, we use relays and the Cheetah SPI Host Adapter. We are using LabVIEW to control the relays, which select the cables to connect to the CS, MOSI, MISO, and C...

I am trying to use the Aardvark I2C/SPI Host Adapter and Python API to emulate an I2C slave sensor that conditionally changes its response values depending on what the master device writes to it. When modifying the aai2c_slave.py code, I get a message with "error: non-I2C asynchronous message is pendin...
