Hi, I'm using the Tait Flash PIC Programmer and "Classic" interface, I can program a 16F877 but not a 16F877A, what is the difference between both? I can read, erase but not Write the 16F877A. With the 16F877 everything works OK. I try changing the differents soft

I have a weird issue. I've used the hardware I2C on the PIC 16F77 with no problems between multiple chips using 2.7K to 4.7K pull up resistors very successfully. However when using the 16F877A I'm finding that I2C isn't reliable at all unless I use 22K to 47K pull ups. Weird huh?

Hi, I was wondering if there is a preference ina aprticualr PIC model that is use more often for robotic. I know the 16f877a is a good general purpose but is there anything better. I mean, something that is 1) well supported, 2) has plenty of program memory 3) has the features that robot builders like like PWM ADC channels and what not. Again, it has to be something common. Maybe theres

Lets ay you are on a budget and you already have some 16f877a pics laying around and a bunch of other parts (resistors, caps etc etc). You have your compiler and pic programer and what not. Now you want to create a program and control your pic. Maybe make it blink an LED. SOmethignsimple. What would be the easiest way to do this. Take into account the cost. For example you can get free C/C++ ...

I have trouble getting the 20 Mhz oscillator to work with 16f877A Oscillator: Saronix 9942k 20.0000 Mhz NCH060C This is what I have done so far: 1) I connect the 20 Mhz oscillator to the OSC1 of the PIC and leave the OSC2 open. 2) I define my oscillator speed as

hai to all, Iam using pic16f877a and 16 x 2 lcd to display my string as an array. The problem is when i touch the crystal legs, I could find the characters display steadily or else the display is flickering. I use a 4mhz crystal. I even grounded the body of the crystal. But eventhen the problem occurs. I use 33pf decoupling capacitors for the crystals. Please help me out. thanks siv...
