Wow Last time I used Flowcode was when it was in v3. Now it is v8. You guys certainly gone a long way from back then. Any plans on supporting the Intel® Movidius™ Neural Compute Stick? Is it possible to write actual programs (.exe files) ? Perhaps combine it with some cognitive architecture (SOAR, A...

Hello

What I really like to see is a servo component and a servo signal input component. These two are quite tricky to program using the present components and it is even harder to have them both in one program.

Hello

Thanks for the tip, however if I were to use the pic to drive servos as well, then I would need the tmr0 register to provide the interupts neccesary to produce a PWM output for the servos.

Hi

Can the pic receive pwm from a source that normally drives a servo, like an RC Gyro? Is there a way that, something like this, can be done?
Thanks

it would be nice if Flowcode was able to work with the Parallax P8X32A microcontroller from Parallax inc. Since it is able to be programmed from the USB port directly there is no need for a new programmer unlike the AVR and the others.

Helo I use the config setting so that the pwm goes to RC1 instead of RB3 and used 8 bit values. The problem however persists. No output on RC1. Basically the whole project is a C code block between begin and end with this code inside it: pr2 = 0xFF; ccpr1l = 255; trisc = trisc & 0xF9; t2con = 4;...

Hello I put this C code into a C block between begin and end and I compile just that pr2 = 0xFF; ccpr1l = 32767; trisc = trisc & 0xF9; t2con = 4; ccp1con = 0x0C; ccpr2l = 32767; ccp2con = 0x0C; Pin RC2 which is ccp1 seems to work but pin RC1 which is ccp2 does not. Not even when I configure it f...

I am using a pic 18F4550. I have used the C commands
ccp1con=0x12;
pr2 = 0xff;
t2con = 0x7;
This is to have timer prescaler 16 and the minimum PWM frequency.
I still can't output PWM from the two outputs ccpr1l and ccpr2l. What else must I do?

Hello I am using the C command ccpr2l = FCV_SPEED; to output PWM from the PIC. This command alone however does not specify the frequency of the PWM. The CCPRxl register dfines the duty cycle. The period is set by the PR2 register in conjunction with the timer prescaler. How can i set the frequency o...

I bought a power supply that outputs 12V however its output plug must be congigured by me. It has this signs on it +-o)-- OR +-(o--
Does enyone know which is the polaryty that the board uses?

Hello I just got a pic mutiprogrammer EB006-00-5. It came without an external power supply and I have to get one myself. The problem is that I do not know the voltage that it accepts on the power supply connector ( number 1 in the board layout on page 5 of the document http://www.matrixmultimedia.co...

Hello
Are there any tutorials on how to configure MPLAB to use the Flowcode compiler for C because the MPLAB C compiler is not compadible with the one Flowcode uses and I cant build a project generated in flowcode, using MPLAB.

I have observed that it sudenly jumps to the problematic line. As it can be seen by the segment of code before 300000 it ends at line 612. By the way the problematic code os right at the end of the program. there is nothing after it. Also I can't seem to find the instruction DW in the instruction se...

Hello and sorry for all the trouble. Unfortunatelly I failed again to build the project with MPLAB. Below are the lines from the asm file and the lkr file that are troublesome if anyone can help I would apreciate it. Thank you in advance. ORG 0x00300000 DW 0x0C04 DW 0x1E19 DW 0x83FF DW 0xFF80 DW 0xC...

I am not sure what you are saying but I have put in project=>build options=>project=>mpasm ->disable case sensitivity:ok and I still get the same errors.

if by right type processor you mean the pic 18f4550 that I use, then yes I did configure everithing for this pic.

Hello I output my program in an asm file using flowcode and when the process is compleded i get the following message: Memory Usage Report =================== RAM available:2048 bytes, used:75 bytes (3.7%), free:1973 bytes (96.3%), Heap size:1973 bytes, Heap max single alloc:127 bytes ROM available:...

I use pic 18f4550 and I am trying to output PWM using this code: { ccpr2l = FCV_speed; } { ccpr1l = FCV_speed; } the two channels are implemented in two different C code blocks. However when I try to convert the flowchart into assembly I get the folowing errors: C:\Documents and Settings\Administrat...

Thanks for your help everybody.

umm... for some reasom I can't simulate the file. it stays always in the loop. there is no value in the LCDDisplay. the sample is always -1.

In the component macro for the ADC there are 3 options. SampleADC,ReadAsByte,ReadAsInt. I was under the impression that the SampleADC option starts the conversion and only when another macro is added to the flowchart with one of the other two options enabled will the program actually acuire the valu...

Hello
With the Analog to digital converter taking so much time in convertion is it possible to start the convertion and have an interupt wating utill adcon0 register bit 1 is done, while in the mean time the pic is doing some other calculations? If it is possible how can I do it?
