Hello,
while looking for an easy way to display floating point number on a LCD I've came across lots of threads asking for this.
But none of them gave a good enough solution. So I've decided to combine them.
Yes yes, maybe this is already known for most of you, but maybe beginners will find this...
Hello all,
I would like to ask about cell balancing circuit.
This is the very simple balancing circuit for a first cell:
I can't test this circuit till I make a PCB.
Li-ion battery cells' voltage is 4.2. I'm using a microcontroller (3.3V) to drive this FET. FET is logic level.
So, while...
Thanks to all. Now I understood that this is only achievable with PLL.
Q1: But why it does work with 20MHz crystal?
Q2: So the best way to achieve max CPU frequency is to use 16MHz and multiply it by 3?
Q3: What do you about PLL? Is it ok for high precision?
Hello,
Refering to PIC18F47J53 datasheet it can be clocked up to 48MHz, but I can't make it to work with such frequency crystal. I'll explain everything from the begining:
I set oscillator to be in HS mode and CPU clock division to be 1:1. So, the CPU clock should be 48MHz (with 48MHz crystal)...
