Hi, Every time I select configure from the chip menu my Flowocde appears to "lock up" and after a several seconds I get an error message stating no usb cable found (I think was the message). I was trying to manually enter config bits to work with PICkit 2. I went back to one of our earlier posts tha...

Hi, I installed the latest version of Flowcode the other night, clicking to fast and installed PPP. If I am using a Microchip USB ICD2 or USB pickit 2 programmer is there any reason to have this software installed? Is there a way to un-install this software. I cannot find it in the control panel (ad...

Hi,

Is there any way to make the command line parameters I tested a "default" setting? A file that we can easily hack???

I do not want to have to rename the standard pk2cmd file to match your modified one.

Thanks

Ron

Hi, I just downloaded the latest flowcode version V3 and installed it on a computer that had the old version V3. I did a complete un-install and rebooted my computer. I then did an install and went into the fcd directory. I had attempted to create my own fcd in the old V3. These files were still in ...

PICkit 2 CMD V1.2 WORKS, based on using the PICkit V2.61 windows programming software as one step of verification. Programmer visually behaves like i expect it to, Flowcode reports success, and when I verify the hex file (using PICkit2 V2.61 Programming software), with what was programmed on the 16F...

Hi Steve,

I will test out and let you know what I find.

Thanks

Ron

Hi, I just bought a PICkit 2 with 4 ZIF different sockets for programming various chips. Thought it would be convenient to be able to program in a single push of a button. I saw that Steve said he edited the PK2CMD to get it to work, I think it was in 2007. Any chance the latest version 1.20 (2009 d...

Hi, I was wondeirng if you could create a cross reference command for us. We have this ability in all of our PLC and PC based control software. The cross reference is automatically generated with each re-compile. Then we have the ability to search on any particluar variable and we are shown every sp...

Hi, If you want to "use" a global variable in a macro MUST the global variable be passed into the macro as a parameter or can it simply be hard coded in the macro? I do not want my main program to have losts of loops and jumps in it. I would prefer it to be made up of mainly macro calls. My situatio...

Hi,

Just got the word from Microchip.

2RX and 1TX buffer PER UART

Thanks

Ron

Hi, I am still new to much of this, but having a great deal of fun with Flowcode. I tried to locate an input buffer for BOTH the RS232 ports on the 18F8722. Some PICs I have used have a 2 byte input and a 1 byte output buffer. I could not find anything like that for the 18F8722. I did find an input ...

Hi,

Will there be any DUAL RS232 support for chips that have dual RS232 built on board? What I mean to say is will flowcode allow for 2 RS232 components to be open at the same time?

Thanks

Ron

Hi Benj,

Thank you for the help, I really appreciate it.

Any ideas when Flowcode V4 will be out for PIC?

Thanks

Ron

Hi, The 40 pin PIC;s have a Vss & Vdd on each side of the PIC. I know it is good practice to place cap across Vss & Vdd as close as possible to the chip. 1) Is it OK to run trace from one Vdd to the other under the chip, same with Vss? If yes.... 2) Do I need 2 caps, 1 per set of Vdd & Vss, or is a ...

Hello,

My wife bought me a PIC development board with and LCD built on it. The data sheet states is has a KS0066U controller. Will this type of LCD word with Flowcode?

I have attached the data sheet.

Thanks

Hi, Several months ago I saw (Microchip web site) what appeared to be some, soon to be released DIP packaged PIC's that had built in support for 2 COM ports. I have not used Flowcode for a few months and was wondering if you currently/will/have added any of these chips to the support list. I would l...

Hi, Can anyone help me out please. I want to communicate between 2 PICs via RS232. I was wondering what is required from a hardware standpoint. Does anyone know where I can see a schematic showing how to do this? I know to have a PIC talk to a PC I must go through a MAX232 to convert voltage levels....

Hi, I have been looking at the hex files and have found the same code at the end of each of about 8 programs. The value is 0011. Is this an end of program code? If yes, is there any way for a program to extend past this marker and still have the program run? I am trying to get a read flash command w...

Hi Benj, Thank you very much. Since I will be using this with RS232 COM macro, I will be using BYTES. This will not be hex values so I will be using decimal, can I use decimal values where you used hex? num_bytes = 5 temp_calc = 0 idx = 0 0 = data[0] = 23 data[1] = 255 data[2] = 0 data[3] = 162 data...

Hi, I want to calculate a check sum and found this on the web and it sound right from how it has been described. An example of a simple checksum: * Given 4 bytes of data (can be done with any number of bytes): 0x25, 0x62, 0x3F, 0x52 * Step 1: Adding all bytes together gives 0x118. * Step 2: Drop the...

Hi, I have had a bootloader written for me by a person in Romania, what a mistake. He was able to get the external OSC for 4 & 20 MHz very easy. After several failed attempts at the 8MHz internal I am concerned. He has only gotten the 4MHz to work and I had to set OSCCON to 0x70 to get it to behave ...

Hi, I need an explanation of memory in this PIC. I wrote a program for 16F886 which has 8K of flash memory. I recompiled it for the 18F2620 which has 64K flash memory. The compiler says that my program has used 87% of 8K memory for the 16F886, it says the same thing for 18F2620 (8K). If the 18F2620 ...

Hi, Is there an easy way to test a program that is simply reading the COM port? Can Hyperterminal be used? I want to send a single ASCII character from hyperterminal, receive it as a BYTE in flowcode if BYTE = 50 (R) turn on RB1, then go back and monitor comm port again. If BYTE = 51 (S) turn off RB...

Hi, I am working with a hardware designer for a basic PIC design, 16F886 and 18F2620. I called out the 2 HW PIC pins for 3 position header, standard toy servo connector. The designer said he was not sure if PIC HW PWM pins would run slow enough to be able to control the toy servos. First question - ...

Hello,

How does

In C code: wpub = 0xC0;

relate (0xC0) to the Pins RB6 & RB7?

Thanks
