    What is Radio board considering Silicon Labs BGM13P module?

    I am about to buy silabs BGM13P BLE module as given in this linkhttps://www.mouser.in/ProductDetail/Silicon-Labs/BGM13P22F512GA-V2R?qs=sGAEpiMZZMsGelYiB%252bjhZoug4L%2fWODSM7Fx4KdEhVtKbmv0yCxCjZA%3d%3d But while reading the information on Silabs website for this module I came across this Radio...

    [SOLVED] How current is limited in this charge controller?

    One more point, I didn't understood what you mean by this? Sensibly sized?

    NRF24L01+ interrupting MCU only once.

    Hi, I am using NRF24L01+ as wireless communication medium. The NRF on PRX side interrupts MCU only once for recieved data. Although it sends ACK to NRF at PTX side. And I have also seen that this NRF at PRX side "discards" data recieved, by polling the registers. Same problem was faced by one...

    [SOLVED] How current is limited in this charge controller?

    How PWM can be used to limit current? PWM can the vary voltage only, isn't it?

    [SOLVED] How current is limited in this charge controller?

    Thank you Brian and Warspeed. I was stuck at this point.I am happy that there is no need of current limiting! PWM voltage control is quiet easy.

    [SOLVED] How current is limited in this charge controller?

    Hi, I am about to build this kind of PWM charge controller but using PIC MCU. But I am not getting how current is limited in this? In that instructable author says:"The amount of charging current is determined by difference between battery voltage and charge set point voltages". But how...

    [PIC] PIC16F877A produces an output voltage of only2.5 to 3 v not 5v when progrmed to high

    share your code with us, so that real solution can be given. And whihc dev board it is? Do check various configuaration settings like PWM, Timer1 OSCEN, OSC switch etc... Wrong setting of this bits can create various problems.

    How to apply PWM signal to H-Bridge made of MOSFETS

    Actually this schematic was for motor control and I am using it for multilevel inverter by replacing Highside N channel MOSFET by P channel MOSFET. And yes my problem is solved.This is the modified schematic:

    [SOLVED] How to copy a particular char from char string to a single char

    I am trying to work with PIC and GSM communication. In that as a notification after receieving SMS GSM sends string as:+CMTI: "SM",5. So I want to copy that '5' in a char. But though copying it the value in the char becomes garbage value and not '5'. Here is the code snippet: char SMSL; // this...

    How to apply PWM signal to H-Bridge made of MOSFETS

    I am using P channel mosfet in high side. And I am using cascaded H bridge multilevel inverter topology. So I am using H bridge.

    How to amplify 2mV signal to 100mV?

    Hi incol, If have used OP07 in more critical application than yours, its really very appreciable. And you use normal non inverting amplifier, it shall help for your application and set gain as according to your requirement.
