A volume production solution often relies on simultaneous gang programming of different target boards to meet speed and throughput requirements. This programming scenario may integrate Cyclone programmers into a fixture which interfaces to a panel of boards to be programmed. Programming is commonly controlled and monitored from a local computer, especially when customized dynamic data is being added to the main binary image that is being programmed into each target.
How can I send large data transactions, messages greater than 64 bytes, using the Aardvark I2C/SPI Host Adapter?
Question from a customer: For a communication scenario, I am using the Aardvark Software API for data transactions. Here is the call that I am using: aa_i2c_write (handle, deviceAddress, AA_I”C_NO_FLAGS, numbytes, bufferin)
If I define numbytes=300, is there a limitation when sending data due to the buffer size of 64 bytes? In other words, I would like to know what is the maximum size of data (number of bytes) that the Aardvark I2C/SPI Host Adapter can process.
Response from Technical Support: For the Aardvark adapter, the buffer space is 64 bytes, and the maximum slave response is 64 bytes. However, the transactions can be much larger. Here are the details:
Major players in the tech world such as Apple, Samsung, Sony, etc. are betting big on wearable technology. Even chipset manufacturers such as Qualcomm and Intel are foraying into the wearable tech arena in the form of wearable sensors. This clearly tells us that the craze to own a wearable gadget isn’t a passing fad, it isn’t going to fade away anytime soon.
A Host Bus Adapter (HBA) is a circuit board or integrated circuit adapter that provides physical connectivity between a host system (computer or server) and networks and storage devices. Apart from the physical connectivity, an HBA also performs input/output (I/O) processing. With an HBA, the host computer’s microprocessor doesn’t have to perform data storage and retrieval operations, resulting in a performance boost.
If you've ever wanted to recreate your oscilloscope screen, it's possible in Excel. This example regraphs both analog and digital waveforms. And this is how to do it:
GPS data has been system integrated with UART for some time, an asynchronous system. With navigation becoming more prevalent in commercial products, as well as mobile robotic devices and the coming of self-driving vehicles, I2C is now being integrated with GPS signals.
These interfaces appear similar, both having two signal lines. Beyond that, their functionalities are very different. Here are two key points:
1. A more sophisticated protocol, I2C can interface up to 27 devices: there can be multiple masters, and each master can communicate with all slave devices.
1. UART can only interface one device to one other device.
2. I2C can operate at a much higher speed than a UART, up to 3.4 MHz or even 5 MHz in some applications.
2. The UART bitrate can be much lower than I2C – the maximum baud rate is typically less than 1 Mbps.

Since its introduction into the market 2 years ago, the SIGLENT SSA3032X has grown to become an industry standard due to its excellent performance and value. The ‘3032Xs come equipped with a built-in preamplifier and achieve a -161 dBm/Hz displayed average noise level (Typ.) for excellent small signal measurement capability. The low noise figure (-98 dBc/Hz ) and amplitude accuracy of<0.7 dB, provide more accurate and reliable measurements than other models in its class.
Now, there is even more to be excited about!
We have lowered the price. You can get a SSA3032X at €2259!
More than that, the latest firmware upgrade provides free 1 Hz RBW selection! Most analyzers in this class stop at 10 Hz! We have also added the tracking generator, a €169 option, at no charge!
