Re: Radio Clock with DCF77

People @Matrix told me this article already existed, I had already made my own Flow to use DCF77. I didn't really look at Spanish_dude's code, but here is mine. My goal was to implement a "radio controlled" clock in an existing project with as less possible code. My approach is to use the ...

Re: How to transform a 10bit int into two 8bit byte ?

Hi Mathy,

There's a great article about this kind of thing here:
viewtopic.php?f=26&t=7451

By the way, the "|" symbol means a bit-wise OR operation. In the example, you can also use a "+" operation.

Re: Look Up Tables using Flowcode and Microsoft Excel

To help you are are two different ways you can convert from byte to integer and vice-versa IntValue = ByteLow+(ByteHigh << 8) ByteLow = IntValue & 0xFF ByteHigh = (IntValue >> 8) & 0xFF IntValue = ByteLow+(ByteHigh * 256) ByteHigh = (IntValue/ 256) ByteLow = IntValue - ByteHigh* 256 Not tri...

Re: I2C

Hi Mario, I have taking a look at you flowcode program, And what I think is wrong is as follow; I understand that you are using a DS1307 (RTC) First thing I found is that you are not giving the DS1307 a read or write command. If you read the datasheet carefully you will notice that the DS1307 has a ...

LCD On PortA ?

Hi Ive just written a program based on splitting/combining 2 8bit bytes posted by medelec a few days ago. This allows the decimal numbers to be entered on the keypad, and then shown in binary on 2 x LED e-blocks and in decimal on LCD e-block. The program works fine, but I dont know why, as I made th...

Using Interrupts to scan Keypad

Setting up a keypad in Flowcode with interrupts. Using interrupts to determine if a key was pressed, frees up the PIC to continue with normal operation, without the need to periodically scan for key presses. The attached Flowcode sample makes use of the PORTB interrupt, which will automatically jump...

However with a quiescen...

Re: variable manager

Hi there. We have a list of features that we are working towards but we occasionally tweak this as new possibilities become available. My worry would be if we posted a list it would be taken as 'definitive' and if features on there didn't make the final version there could be complaints. Anyway, per...

Re: battery meter

Hi !

I think it's because you use the return value "in" which has to be a floating value but is a byte.

I have tryed to do it on another way. I have no problem by compiling to hex but not testet in "real world". try it. :?:

Dual Channel Temperature Logger - Remote Ch2

This article shows a simple modification to my system to allow remote monitoring The LM35 is a very useful device, however if it is mounted any distance from the microcontroller, the voltage drop in the cables can introduce errors. 10mV/°C equates to 1mV/0.1°C. i.e. for every mV lost gives an error ...

Re: Controlling a Servomotor with timer0 interrupt.

Hello Martin, Have you yet test the routine in actual hardware with servo? Did it worked? Also, ( excuse me if I am wrong but I am just a hobbyist!) in order to achieve the 0.1 ms interrupt interval shouldn't the interrupt frequency be set at 10 000 hz instead at 7812.500 hz as it appears in the int...
