    Re: Reverse polarity in Direct serial data

    Never thought of that! Very good idea. A little bit of rearranging might do it.

    Thanks!

    Reverse polarity in Direct serial data

    I was struggling to get it right with direct serial data (no rs232 drivers etc).

    One PIC, a 16F1827, was set to transmit RS-232 serial at TTL level and the bit 4 of BAUDCTL was set for this. The...

    Re: Conway's Game Of Life

    Just amazing!

    Although I never fully understood that "game" your work looks impressive, especially on this P10 display in wide format.

    Nice job that video on YouTube also!

    Re: Mplab icd 2

    Your ICD2 should have a jack with 6 pins. So you need a cable with telephone-like connectors of 6 pins.

    The on your board a female jack of 6 pins (also 8 of the ethernet type should work) and the...

    Re: RF Communication over ESP, BLE or other

    ESPs are not communicating on TCP protocol.

    Using ESP-NOW the communication, as Francesco says, is rapid.

    Have not tried it yet. I have no experience on the ESP modules and need some reading...

    6m? that is not distance... that is besides!

    Are you sure that your modules are OK? Seems too short. Even BT does it better.

    From the Annex forum, Francesco (the developer of the Annex WiFi I...

    The project is about controlling small car for children. They are owned by renting shops.

    These are electric remote controlled cars with one or two 12v/7a batteries, 2-5 motors like the ones in...

    RF Communication over ESP, BLE or other

    I need to make radio remote control with this needed specs:

    1. The remote controller should be light, small and low battery consumption
    2. The range is not much important. Anything between 50-150...

    Re: Battery power back-uped circuit

    Roger,

    The important specs is dependent on the application.

    For example, if you drive the MosFet from a logic level chip, say a MCU, then you want the Vgs to be as low as possible for the...

    Re: Battery power back-uped circuit

    Because according to Electrical Specs, the FVR may be from -8% to +6% for example on 16F1827.

    I would not trust this to charge a LiPo battery at all!

    Re: Battery power back-uped circuit

    Roger, the minus Vgth is correct. Consider it a different visual angle!

    In P-channel or PNP transistor the voltages are the opposite of the N-channel or NPN transistors. Means that the voltage og...

    Re: Battery power back-uped circuit

    FVR is not at all accurate, so that 4.25... I doubt you are safe.

    Re: Asm sleep - pbp sleep

    Glad you did it! Similar cases we faced I guess too.

    But that makes me wonder, if we try so hard to solve such things on a PIC, what would happen on a more complex MCU? Would then take years to...

    OK, here is the explanation about the NOP:

    When the SLEEP instruction is being executed, the next
    instruction (PC + 1) is prefetched. For the device to

  25. Re: Problems programming a 10F206 PIC using the Melabs U2 USB Programmer

    One problem seems to be the calibration that might be lost. On my programmer (Elnec Pikprog+) there is a checkbox to preserve the calibration before erasing the chip. Please check that on yours.
