Support Question of the Week: To Save Board Space and Not Include a Connector on the PCB, How Should I Connect the Beagle USB Protocol Analyzer?

I am working on a new design that will be installed in a system. To do so, I need to save board space. My target USB bus is inside of an embedded system. To analyze and verify the results, I'll need to tap off the lines to monitor the USB bus. To use the Beagle USB 480 Protocol Analyzer, I think I'll only need to wire in GND and the D+/D- signa...

Support Question of the Week: Using the Aardvark I2C/SPI Host Adapter, How Can I Configure the Flash Center Software Parameters to Program SPI EEPROM Devices?

I have multiple AardvarkTM I2C/SPI Host Adapters and I plan to use them for a production flow; programming SPI EEPROMs (Microchip 93AA56AT-I/OT). It looks like this device is not supported by Flash Center Software. Also, to program this device, it looks like polarity needs to be set as "active high". Can you send me information about editing SS ...

Support Question of the Week: How Can a GPIO Interface be Created for the Cheetah SPI Host Adapter to Control the Reset Signal and Pulse Periods?

I am using the CheetahTM SPI Host Adapter and would like to use it to program an SPI device. To set this device to programming mode, I need to do the following:

  1. At power on, set the Reset pin, and set the SCK pin for low for 4.7msec
  2. Afterwards, send a 4-bye command

The Cheetah adapter does not have GPIOs - how do I control that signal? Also, ...

Support Question of the Week: How Do I Use the Komodo CAN Interface to View Retried Transmissions on the CAN Bus?

I just purchased the KomodoTM CAN Interface and I need to count the number of retried transmissions on the CAN bus. How can I do that? Please advise.

Thanks for your question! The Komodo CAN Interface monitors the CAN bus for traffic that is sent by the Komodo, as well as the traffic that is successfully sent by other devices. The retried trans...

Support Question of the Week: How Can I Quickly and Program SPI Memory Devices With an SPI Host Adapter?

I will be using the Aardvark host adapter to program a series of SPI memory devices. This is a high volume project - what is the fastest and easiest way I can do this?

Thanks for your question! The AardvarkTM I2C/SPI Host Adapter is often used to program SPI memory devices.  For your application, we recommend using the Aardvark adapter with th...

Support Question of the Week: How Do I Support Reading 16-Bit SPI Data Samples at Higher Frequencies with an SPI Host Adapter?

I am trying to sample IMU (inertial measurement unit, M-G362PDC1 by Epson) data at 100 Hz but my setup misses some of the 16-bit SPI data samples.  Here’s my setup:

  • I am using a MacBook as the host and the AardvarkTM I2C/SPI Host Adapter is connected for SPI communication between the computer and the IMU. The Aardvark is the master; the IM...

Support Question of the Week: Which SPI Host Adapter is Best for Simulating a MCU When a Programmed Delay is Needed Between Bytes?

I am looking to use an SPI host adapter as a master to simulate a MCU (multipoint control unit) for an application - this MCU in the design phase. Another existing MCU will be used as the SPI slave. In this simulation, I need to send an 8-byte message on one slave select. The first byte will always be the message ID, which the microcontroller ne...

Support Question of the Week: How Do I Connect the SPI Host Adapter Signal Pins and Program Unsupported SPI Flash Devices?

I'm trying use the CheetahTM SPI Host Adapter to program Micron SPI flash devices N25Q256A and  N25Q00A. I  have two questions:

  1. Do you currently support programming N25Q256A and N25Q00A?
  2. Listed below is the IO pin list for the N25Q256A13ESF40F. Can you tell me which SPI flash device signal pins to connect to  the Cheetah adapter signal p...
