I thought that I'd try out another of the basic overlays before moving on to a neural network application.   The PYNQ development software provides a set of logic tools using the logictools overlay.  You can create a digital circuit by specifying its function and IOs with a simple, declarative API in Python.   The logictools overlay has 3 function generators plus a trace analyzer to capture generated patterns. Boolean Generator - up to 26 independent Boolean functions of up to ...
I'm continuing my exploration of the base overlay to control the external peripheral interfaces on the PYNQ-Z2.  The 3 interfaces are the Pmod, Arduino, and Raspberry Pi which are each controlled through a separate soft-core Microblaze processor.  The MicroBlaze instances are referred to as IO Processors (IOP) and there are actually 4 IOPs in the base overlay as there are 2 PMODs (A/B), the Arduino IO, and the Raspberry Pi IO.  PmodA  shares its 8 data pins with the RPi inter ...
The MCIMX7ULP-EVK is the i.MX 7ULP Evaluation Kit, which provides a platform for rapid application development using the i.MX 7ULP, featuring NXP's advanced implementation of the Arm® Cortex®-A7 core, the Arm Cortex-M4 core, as well as 3D and 2D Graphics Processing Units (GPUs). Recently, I got a chance to test drive.     In June 2019, NXP released an addition to their i.MX 7 Series, the i.MX 7ULP, which is the latest achievement in ultra-low-power processing for use cases ...
Course module 12 finishes up by implementing a weather station device using the the Environmental sensors and the BLE device.  This course module is another example of the course not being finished before it was released.  There are 3 lab videos, the first one is a combination of the following two and probably should have been deleted.   In module 11 I encountered a problem where the device did not seem to be advertising its BLE characteristics.  I wondered if this could be ...
Course module 11 describes connecting things to the Internet and Cloud services.   I think the proof reader didn't get to these slides .  In the Module syllabus, I don't think that "Try to keep bullets short and to a minimum" was a topic.  And on the topic of IPv6, I think the world's population must have exploded if each person can only get 4000 addresses.     The proliferation of network devices - driven by mobile phones and IoT devices has necessitated the adoptio ...
In this post, I examine in a little more detail how well the Sensor Cube and the Wireless hub's antennas and wireless communication can work. In talking with lui_gough and others, there may be some distance limitations that are not as good as they could be. This is written as a follow up to my recent Road Test of the IDT Wireless evaluation kit as the official evaluation period is closed now.     I came up with a few simple tests which I will show the results of below. For the sign ...
