I have started on the path of working with the QuickFeather board from SparkFun. There are some gotcha’s I was able to solve along the way that might baffle some people. My solutions may not be ideal, but here they are. I found that reading the quickstart guide was...

The study into acquiring a cheap debug environment for *any* arm processor is complex and confusing. I previously wrote about using a SEGGER, but that was not ideal. The reason is cost. One can be had for about $90, but it is iffy to use as a debugger at...

Just received the $90 XMC-Link. The 0.05″ connector cable is ARM specific. The larger 0.1″ connector cable is XMC specific. As a bonus, it is DC Isolated, 1KV, so you can debug processors at different grounding points than your computer. I plugged it into my Macintosh, ran JLinkExe that...

Because the PSOC5LP is not readily available for the Weekend Engineer (no CY8CKit-059 boards available now), I have had to look elsewhere. The EOS S3 has caught my attention, but it is in the early stages, and I am not certain how much effort QuickLogic will put into it....

To be perfectly clear, if a manufacturer provides good support for their product, you should buy from them, regardless of the cost. However, if you are scraping by on less than optimum wages, that is sometimes not possible. Period. In that case, people often turn to Chinese knock-offs. In...

Since Infineon has made the PSOC5LP parts and dev kits unobtainium, I am having to look at other products for low volume production at work, and for SocMaker Weekend Engineering. QuickLogic has a processor that combines a tinyFPGA with an M4F processor and a 12 bit A/D. SparkFun has...

I am a proponent of the PSOC5. If the PSOC6 had as many UDB’s in it, I would be on that bandwagon. If it worked at high temperature (not yet tested), at the office we would switch to it ASAP, even though it is NOT 5 volt tolerant. The...

Here is information from one extraordinary Monday….. I have two old Macbook Pro 3,1’s. One is a 32 bit, one is a 64 bit Core 2 Duo. The hard drive on the 32 bit failed. I had an old 128gb flash drive so I threw it in there, wanting...

I was viewing some interesting YouTube videos concerning the current world economic emergency. Mexico has declared it is in a recession, using the metrics the current USA administration is declaring are now incorrect. The government says if the economy stays in this recession, then the economy will eventually be...

I received a comment that the USB port on the CY8CKit-059 is causing a timeout. This is from a Thesis. I looked at the student’s code, and it is slightly different from my implementation, so I suspect something is missing. I borrowed the code from the automatically generated API...
