    CMOS Crystal Oscillator Circuit

    Thank you very much. That's exactly what I wanted to know, and that's exactly what I call a very helpful reply. 1664327644 Thank you Dana. That was very helpful, too! So, basically for lower frequencies, jitter is minimal. 1664331010 Klaus, For goodness sake, no one claims to be perfect, and...

    CMOS Crystal Oscillator Circuit

    Klaus, Be certain that I never rush to ask questions without doing my homework and research on my own. And I'm not always asking questions for every tiny issue I face, unless a clear and definite answer was not available. For this one, I really didn't ask about the clock input of my MCU. Please...

    STM32 Clones/Alternatives from another maker?

    Hello, I know the GD32 MCUs, clones/replacement of some STM32s, are out there for quite some time now. But has anyone heard of AGM32? I have found this by coincidence yesterday and I'm quite impressed: AGM32 AG32F407 core is much faster (248 Mhz) with all necessary peripherals. But where to...

    CMOS Crystal Oscillator Circuit

    No, not relatively that large number. Do you have any reference for these modules, datasheet, PN, etc. 1664276238 By the way, what is the difference between supplying the clock (16~40 Mhz)from the above crystal oscillator circuit vs the output of MCO pin in the STM32. And in case of the latter...

    CMOS Crystal Oscillator Circuit

    Thank you. That was very helpful. The original circuit has been copied from: https://www.electronics-tutorials.ws/oscillator/crystal.html 1664157658 Thank you! 1664157927 Thank you Dana. That was an interesting read! Zaher 1664158720 Right. I have several circuits/implementations that all...

    CMOS Crystal Oscillator Circuit

    Hi, If this is not the place to ask this, please move at will! The following is a CMOS Crystal Oscillator Circuit that generates a square wave: I will use this circuit to supply the clock needed for a legacy device that accepts clocks in the range of 10~40 Mhz. Is this the best way to do it...

    I need help building Yocto (poky) for a specific HW/Target > Licheepi Zero Dock (Allwinner V3S)

    Hello everyone, My first exposure to Linux build systems was almost 3 months ago, when I got the Licheepi Zero Dock board. For those who are not familiar with this board, you can see it here: LicheePi Official website I had no problem getting familiar with the toolchain and building/burning...

    Why you think an FPGA/CPLD is better from MCU for interface and protocol bridging applications?

    Thank you again for the input. I almost found the solution based on certain devices from Cypress/Infineon. One of the solutions is to use an off-the-shelf Cypress/Infineon device that can provide the bridge application I'm looking for. Another solution would be interfacing to the CPLD I...

    Why you think an FPGA/CPLD is better from MCU for interface and protocol bridging applications?

    Yep, I totally agree. That's actually what I'm trying to achieve. By the way, you seem familiar with Cyperss/Infineon ecosystem. I went to their website yesterday and spent some time reading many datasheets and reference designs for products similar to what I'm trying to achieve. It seems I've...

    Why you think an FPGA/CPLD is better from MCU for interface and protocol bridging applications?

    Thank you Dana. These might be great for many designs. I've seen them on Cypress' a couple of years ago, but totally forgot about them. As far as I remember, I made support request asking whether a DMA with full DREQ/DACK handshake mechanism can be implemented using these devices. They must have...

    Why you think an FPGA/CPLD is better from MCU for interface and protocol bridging applications?

    Hi Klaus, Well, I know I didn't elaborate much about the specific application intended, but this is for a commercial product and I'm not sure if I can expose much about it here. I have read several ALTERA/INTEL and Xilinx literature on their devices and I read on many pages things that say FPGA...

    Why you think an FPGA/CPLD is better from MCU for interface and protocol bridging applications?

    Hello, I've been doing many embedded designs based on MCUs for quite so long. I have never used an FPGA or CPLD in any of my designs. However, I have a classical protocol interfacing/bridging application where CPLD seems a great fit. I even found many open and free IPs for some of the intended...

    Interfacing a 1 Gbit NOR Flash (M29EW) to STML552ZET - CFI register always returns 0

    Hello everyone, I'm trying to interface a 1 Gbit NOR flash to a new custom board with STM32L552 as a target MCU. The flash is connected to the FMC using 16-bit data bus, 26 address lines, and the rest of control signals. Right now, I can confirm the interface works by reading the correct values...

    [SOLVED] HotPoint Ariston Refrigerator Power/Control Board (NMBT 1912 F T/ha)

    Hi Klaus, Thank you. You were correct. I thought I would give a good description to the problem and will follow it up with some pics. Anyways, I have reassembled the board and the refrigerator is back to work again. I don't know if removing the LCD module for several days had anything to do...

    [SOLVED] HotPoint Ariston Refrigerator Power/Control Board (NMBT 1912 F T/ha)

    Hello everyone, I bought this refrigerator from the 2nd hand market. It's been working fine until I realized that something is wrong with the defrost system. I had to manually turn it off for 5~8 hours from time to time to let the ice melt down in the freezer and allow air to circulate again...
