Hi all! I need to build a simple sensor for water. The classic method with one transistor with the probe in it`s base is not viable, the probe is "vanish" in time because of the electrolysis phenomenon :D . I did a sketch with an ADC input and one output. The problem is that I want to disable the AD...

Thank you a lot for the reply and for the link! I did not know that blog,for me it is a fortune!
I have not worked with SPI yet but I will try, if I`ll get stuck, I`ll be back
Thanks again!

Puiu,

Hi guys!
I need your help again!
I have this RFID and I want to interface it with FC 5.
There is a way to do it? If yes, how?
Thank you!

Puiu

Thanks for your reply!
In the mean time, I manage to alter your original flowchart with RC5 component and its working ok!

Hi there!
I want to make a remote control with 10 buttons.
For this, I chose pic16F1828 because that has 10 IOC. All well and good, but I can not manage to alter your code for my needs ... I post my altered version for the 16F1828 and please, when you have time, to correct my code.
Regards, Puiu!

When will be ready, i`ll post all files. It is an wrist clock with 7 segment leds.
For the moment, I have some trouble with the charger on board for the Li-Po accu...

I already solved, thanks for the support.

Just out of curiosity: For version 5 of Flowcode is still providing support?
Thank you!

Yep, mean time I manage to communicate with it... But still need help to use all feature of the chip (temp, alarm, etc.).
Also, I need help to display on 7segment some custom characters.
Thank you!

Puiu,

I`m working on a wristwatch. The HV it`s almost ready. In the mean time, I want to work at the software, but encountered a problem, I cant handle with DS3231. I thought it is the same as in 1307 but it does not work at all... There is anybody on that forum to help me with an example with DS3231 for ...

The same situation... RB1 is low
This is the schematic:

I need to enable weak pull up for all bytes of the port B, thank you!

I need to activate for the 18F252 internal pull-up and I cant handle... I put a C code icon with the "intcon2 = 0;" but it activate INT1 at the RB!. How can I clear only the RBPU (bit7) of the INTCON2 register? I tried with "clear_bit(intcon2 , 7);" to but the result was the same: All port B is "up"...

I think you forgot to put a pull-up resistor (10k) on the data pin of the TSOP.

The goal of this "controller" is to run 6 stepper motors in a loop a while (the timer is set in master too). Once all settings are transmitted, the slave wait a start command (a sw). All it have to do is to run all 6 motors with the parameters transmitted in cycle, when the number of steps in one di...

I have 6 sets (6 motors) by 4 parameter and another 2 variable that represents hours and minutes of a timer. The 4 parameters of the motors are: 1) on/of (active -1, inactive - 0) 2) speed from 1 to 30 3) Cycle (how much steps to run, in fact, represents degree because the motors are connected to so...

I think that I find the way out :-) But, There is only one problem, for the very first time, when I receive the bits, I lost the first byte. If I made "Counter=255" at the beginning of the program, I catch the first byte. Why is that? In the example I have made only for 5 variable, but I have 26 to ...

Sorry, it was a typo... *.fcf tried to upload... I can not upload archives too.

I have all the buttons but when I push the "Add the file", the answer is "The extension is not allowed.". The file is *.FCV
I can not access the forum directly from the browser and I use an proxy server to access here, it is a problem with my IP class or something, don`t know...

I have 26 bytes to send and receive. I made an macro for RX_INT where is an RS232 receive macro component and the received bytes are return value in the RX variable. In the Main macro, I have an decision and when RX <> 255, then, to the yes answer, increment an counter and after that, is an switch c...

I give up ! Can' t "catch" all bytes... I think that I will return to my loops...

Aha, so this was the mystery, it cannot be simulate... I`ll try in pic
Thanks Martin!

Thank you for your reply!
Yes I have the last ver. of Flowcode (5.5.2.1)
And Yes, I check the C code and all that lines are there ...
Strange, if I push the erase button on the received or sent bytes, the bytes appear in the queue window...

I still have not managed to use the RX interrupt.
Any help is welcome.
Thank you!

I alter my Slave_test with RX_INT but nothing happens. When I send the bytes, the receive window on the Slave_test is black but if I push erase button (at received bytes), in the buffer window of the Slave, appear all the bytes and stay there. I can`t put the file here today (don`t know why), i put ...
