thanks for the reply. i understand,
There can be faults "everywhere" in the code and i don't expect someone to review the code. (There isn't any good cause).
If someone can provide me an algorithm, or atleast give me an idea, or atleast tell me how its done, that will be good enough and i can...
Hi Guys,
I'm trying to transfer data between PIC16F72 and raspberry pi (Model B, Rev2) using a cheap 433Mhz module from Ebay.
I'm planning to DIY a weather station and wireless is an essential part of it. The communication is one way from PIC to RPI and i have soldered a 17.3 cm wire as an...
Hi,
I'm trying to control a LED panel using a PIC micro-controller PIC16F72. I have configured RB4 on PORTB as O/P. Please find the circuit diagram attached.
My LED panel consists of approx 30 Rows of led, all rows in parallel.
Each row has 3 LED in series
Only 1 row has 2 LED's
When i...
Hi all,
I'm trying to build an autonomous weather station. All diy .. I plan to use 2 cellphone batteries (bl-5c by Nokia) . These are lithium ion batteries and can provide good enough power.
I plan to connect those battery in series. I'l design a charger using one of the charger ic (this is...
Thanks a lot guys. I went through both the links http://www.winpicprog.co.uk/pic_tutorial1.htm and http://www.phanderson.com/PIC/16C84/mult_string.html , both provide basic examples of Lookups..
i'll try using lookup tables . I need to display those values on a LCD (later stages would need to...
Thank you, I get it now. we need to do some binary arithmetic in order to get the desired result !
no its not a requirement. I have the rpm "x" and i need to convert it into wind speed. For which i need to do some math. And i thought this is the only way out.
How people working on PIC micros...
Thank you. I thought we could just divide variables using the division operator.
Eg .
If there is a variable
Count res 0x02h
Is this valid ?
Count = count * 0.5 ;
Can the compiler understand it ? Note that the program is in asm.
I've been working on measuring wind speed. I'm using PIC16F72 (easily available) . My circuit uses a encoder wheel and photo diode to sendout pulses. program uses ccp and timer module to measure the period of the pulses.
I actually need to convert the timer count to rpm. For this I need to...
Hi Folks,
I'm using Orcad Layout (v9) to route my PCB (2 layers , top and bottom only). I need to achieve the following requirement,
On Top Layer i have to manually route important traces.
Auto Route rest of the traces on the bottom layer. (No more traces on top)
How to achieve this ? I...
