Ok Steve here is a very strange problem Regarding Keypad. A very simple program getkeypadnumber and return into variable kpn. if kpn =255 print 255 on LCD. "YES " If "NO" Print kpn on LCD. Simulates well, but on the hardware it behaves differently. It is returning different values randomly. sometime...

Steve i am using optrex DMC16105 lcd, 16x1. Problem is simple, if i print ascii usinf cursor 0,0 it displays only 8 characters. But when i print only 8 chars at cursor position 0,0 and rest of them at position 0,1 it displays full 16 chars. It seems fine, but the major issue as the text splits up wh...

Thank you Steve, The Vnet is working fine now. GLCD is very slow. Cant display 16 characters on the 16x1 LCD. Only get 8 Character, I have to divide the text into two parts for displaying 16 chars.....then im left with the scrolling problem. One wire is very confusing. No matter what i do i get a 0 ...

As i am testing the flowcode before i buy it. I am discovering alot of problems. Vnet also not working.
when i hit create it returns with a message "Cannot connect to Vnet."

Haven't made the schematic yet. Just planning to input audio signal via microphone to output the recieved data by rs232 component. I will also use a dac to convert the Tx signal for converting it to analogue again.

What about midi component?

The DC method seems to work but not all the times. At times it takes more than 10 ms. I am using 1uf cap with 1k resistor I will now use the interrupt on falling edge and see if the problem is resolved. As i am exploring flow code. What do u recommend to receive an audio signal? Is it OK to analogue...

Thanks for replying. Ill look for the resources online, then get back to you if the problem persists. Yesterday i was playing around in flowcode. I developed a simple lcd ascii display which simulated in flow code well. But in the real world it displays only 8 characters, i fixed the problem by addi...

How can i use flowcode to design a mains fail detector circuit using pic 16484a and transfer to inverter mode in less than 2 milliseconds.
