Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
LEDs come in all manners of sizes, colors and brightness. To be able to choose the most appropriate ones, we need to know what are they going to be used for. For this purpose, we did some market research on UV curing glues. After checking the datasheets...
First of all, sorry for the delay. Life's been kinda busy and I didn't make any really interesting progress on the project; still, I think I gathered enough material for an update (at least, now you know I'm still alive!).The phoneAnyway, the first major...
Announcing a major new capability: CylinDraw makes for an excellent paper plotter! The hardware needed to enable this capability only requires the addition of a large tube to wrap the paper around and two rubber bands to secure the paper in place....
YouTube How to update CircuitPython firmware This method is suitable for the BPI-PicoW-S3 board that already has tinyUF2 firmware. If the flash of the board is erased or the failure to enter the UF2 mode occurs, you need to refer to the method of burning...
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...
Today, i rewrite a code of ambient light of arduino module applied FastLED library carefully. Why? there are 3 important thing, 1) the legacy code of adalight is based on SPI that is used by a RF module too. I think move pin in code of adalight from...
See Update BelowContext being more that of the puzzle of cases not one case "to rule them all," but I digress. The past week I've been going through a few catalogs to find an enclosure for D-DAQ's mainboard. Previously, the PCB's form factor was based...
You might remember my musings with the XOR gate with interlocked NPN transistors discussed at Bipolar XOR gate with only 2 transistors But thinking about how XOR is done with pass transistors in CMOS and the structure often creates a MUX, I wondered...
