Thanks guys makes a lot of difference getting some expert guidance. Accelerated learning!!

Please feel free to provide insight into developing the ADC block.

Thank you

Hello all,


I want to develop a program that requires a user to input a value such as the weight of an object. How do I set this up so that a range of 0-250Kg can be input before the program starts to take readings from a sensor and makes calculations. Is there an example available please?

I've started the flow chart, I need help with the c-code. How do I use the random value to influence the delays?

Hello, I would like to make interrupt or delays random in a program. So when a button is pressed, a buzzer is activated. A random delay or interrupt of 5 to 10 seconds should elapse, then the buzzer is activated again. A random delay between 2 and 10 sec' duration then starts. Is there a way to seed...

Hello Ziggy 1. More efficient way is to use floating point but this can get tricky and uses lots of memory space on the PIC devices so if what you currently have is working then I would stick with it. 2. Sorry but I cannot go through peoples programs fixing problems etc. I am only here to support p...

Hello 1. How are you doing the decimal point. Is it juat psudo decimal point? 2. Where are you checking for the reset button press? Simply place a calculation in this part of code setting the count values to 0. 3. Yes two switches to set the delay would work. Simply increment or decrement a variabl...

2/ When the stopwatch is paused by the stop button, the reset button doesn't seem to be able to reset the minute unit variable to 0. How do I solve this? 3/ I also still need to know how I can allow a user to change the variable DELAY that determines the time intervals between the lights. I was thin...

Hello Ziggy Try looking at the problem logically with a pen and paper. This way you can plan out your functionality without having to start programming. A good start would be : Enter a set time - Ok how would you do this. Eg using switches etc. Its a year since I thought about this project. I have ...

I want to construct a flow code that is able to do the following, Enter a set time between 10-120 seconds. The entered time can be divided into 2-8 parts. The time is then stored in memory. A count down is activated when start button is pressed to decrement by the time set in memory. A set of lights...

Ben, I have successfully implemented the stop and reset button respectively, thanks for the hint. I want to use a 4 MHZ crystal to generate a 100ms interrupt. I downloaded a piece of software called "Pic Timer Calculator Version 4". The software recommends a timer offset of 100, a prescale...

Thanks great help.

I have adapted tutorial 22 for my stop watch project. I have implement a start button macro with debounce. I am finding it difficult stopping the program as a stop watch. Could anyone suggest how I could implement the stop and reset button please?

Thank you

Thanks for the input. I looked at the examples that came with flowcode 3 in the program files on my computer. They are excellent. I recommend that anyone who needs help with sorting out timing for example will be able to adapt example 22 to achieve what they need. The examples are very very helpful ...

I am in the process of developing a stop watch with min secs and 1/1000th of a second digit displayed. 1/ I am using a 16X2 alphanumeric display. I need help on the refresh routine for displaying the count from the timer interrupt. Any suggestions on how to organise the LCD display subroutine would ...
