  • How 555 timers Work - The Learning Circuit

    The 555 timer is probably the most common and popular IC to be used in hobby circuits. There are A LOT of projects out there using the 555 in various ways and it’s easy to find schematics to make a project that has already been proven. But rather ...

  • RIoT board won't boot?

    I just opened my RIoT board and LCD8000-70T-EX1 and cannot get it to boot the stock android OS. I have followed the directions and setup the environment as follows: setenv bootargs console=ttymxc1,115200 init=/init nosmp video=mxcfb0:dev=lcd,7inch_LCD…

  • How to reset all parts names numerics?

    HI, I'm new here, and have one question. Does eagle have a function like reset all elements names (like resistors, caps and so on) and then to give them new names numerics (from top to bottom, or from left to right..) at once? or you have to do that manualy…

  • Vivado 2020 "No ARM Processor Found in Design"

    I've created a simple design in Vivado 2020.2 that consists of a Microblaze, UART, SPI and LEDs. I enabled interrupts but haven't yet utilised the triggers.: all went well and bitstream was generated, which I then exported along with the hardware. Once…

  • PicoZed USB PHY always in RESET?

    We have an issue in which the USB PHY (USB3320) is always held in RESET. The attached picture describes the issue also. The root cause i s the fo llowing: PS_MIO7 signal is 1.8V due Bank 501 being set to 1.8V. TI AND gate IC SN74AUP2G08DQER is spec'd…

  • Arduino SIM800L Problem...

    Hello everyone! I want to make a small project and I want to send text messages with my arduino. I bought a small SIM800L board but I have a weird problem. This is the board I use, and I connected it to my arduino via SoftwareSerial. The arduino just…

  • Potential Issue on PS_SRST# Signal (MicroZed)

    Hi, While Checking out MicroZed schematics (Rev.E), I noticed that the PS_SRST# signal is pulled up to 1.8V on Page 5. This signal is also connected to RST# pin of the SPI flash (U7), which is pulled up internally to 3.3V voltage (according to it's datasheet…

  • Installing a reset button on Rasp Pi 3

    I have seen where people used the P6 on the Pi 2 to install a reset button and really wanted to do that on my Pi 3. I am just getting started on Pi's and trying to learn as much as I can before I get my son involved. Is it possible that instead of the…
