Question from the Customer:
Can you tell me about the pin configuration of pin 14 and pin 15 of the Promira Serial Platform? I am using these two pins as DO. Are they both open-collector pins – will I need to add pull-up resistors?
Response from Technical Support:
Thanks for your questions! The I/O circuit depends on how you are using the Pro...
If you’re a Criminal Minds fan, you’ll know this TV drama produces fictional and enticing crime episodes where police and FBI agents investigate unique crimes and their perpetrators. One recent episode, “Collision Course”, focused on a crime where hackers targeted vehicles and took control of the vehicle’s controller area network, the...
Question from the Customer:
We’ve been using the Aardvark I2C/SPI Host Adapter for years – the software updates have been great, but now we’re testing a faster prototype SPI device. We need a faster adapter. Our goal: eliminate gaps between clock cycles.
Currently, there is a gap between each 8 clock cycles. For test harness purposes, to ...
Flash Center Software should be used with our Cheetah SPI Host Adapter to program large files to SPI flash memory. A common use case related to this topic is loading field-programmable gate array (FPGA) images to different addresses within SPI flash memory.
When loading large files, you often need to program one sector of memory while leaving o...
Question from the Customer:
I’m using the Beagle I2C/SPI Protocol Analyzer and the Data Center Software. I have a question about the results I see. I send a 20-bit (2.5bytes) data packet, and the results show the data is wrong. The error code is P4, as shown below.
We are certain the SPI data is correct – why is the Data Center Software ...
Question from the Customer:
I was wondering if you have a sniffer solution that allows me to test a single master on a bus? In other words, are there sniffers that respond as slave devices with ACK and returning data? I’m working with SPI and I2C devices.

Thanks for your question! For your test requirement...
Question from the Customer:
I’m using the Komodo CAN Solo Interface with Komodo Software API. Can you help me understand the timestamps? Do timestamps change with the bit rate? What are the units of the timestamp? Here is what I’m looking at in the example code monitor.c, the structure of km_can_info_t:
Question from the Customer:
I’ve been using the Cheetah SPI Host Adapter for a while – today I have a question. I’m working on a prototype SPI device with a data length of 33 bits – it’s not based on a “normal” byte. I’ve been looking at the Cheetah Software API. Is there a function I can use for transmitting variable length d...
Universal Serial Bus, or USB, is one of the most widely used protocols in technology. Most people, from experienced techies to the average consumer, use USB almost daily as it is incorporated into billions of devices worldwide. Over the years, multiple USB specifications have been released, each with improved speeds and efficiency. Particularly,...
Question from the Customer:
I am using the Promira Serial Platform with the I2C Active - Level 1 Application. When using this and SDA line, the clock duty cycle is about 30%. Is there a way to increase serial clock duty cycle for this I2C device? I ideally want it at 50%. Here’s what it looks like on the scope. Channel 1 is the clock at 30% d...
