I am using a 10 bit ADC and 5V supply, so resolution is \$\frac{5}{1023}\$. I decreased my voltage supply to 4V, the resolution now is \$\frac{4}{1023}\$ For both cases, I am reading a constant value …

I bought a new ACS712 current sensor. VIOUT to ground is 2.560 V under no load conditions. This is very accurate as my supply is 5.12 V. I plug in an old fluorescent tube that needs a ballast and sta …

I considered suggestion above that current sensor may have experience interference from nearby magnetic field. Apart from buying the shielding for testing purpose, I using a cheap solution like emf de …

As mentioned by brhans, the Ms delay only reading integer number. After I change the delay to integer number, the display working correctly.

This is my PIC circuit connection in Proteus to the LCD display and everything work fine in simulation. However, in practice, my LCD does not display even the very first line "AC Wattmeter" in the "vo …

My purpose is to measure phase angle between 2 square wave as below(yellow represent voltage ZCD and blue represent current ZCD passing through ACS712 hall effect current sensor) Below is my circuit …

On internet can seen countless simple example like the one below void __interrupt() isr() { if(TMR1IF) {Do something} } But does it work on self-defined variables? As an example, define a bool …

Below are the codes I using to display dates and times and basically I used the function "write(hr1,hr0,min1,min0,sec1,sec0);" to display the time and "day_compute(day);" to display what the day for t …

Based on the explanation given by Tony, I understood the command line and found my mistake already. My mistake is in the void initialize() command originally I using void initialize() { PORTD=0x00 …

I want to create a clock using a timer (TMR2) to do the calculation and display current time. I have a problem dealing with the switch statement and couldn’t identify where the problem is. When I run …
