Hi boys and girlss, Question about the RS485 EB062 board. 1: Will it be possible to use this as DMX slave .. 2: Does anyone have an example program of a DMX slave, to help me understand how to use it. Strange, nothing in this forum about DMX slave's. Given DMX is approximately equal to RS485 and a w...

For those who find it important ...... Communication with the MCP3426 via I2C succeeded. Attached you will find the example program, as it currently operates. There is still to do some work, but with this I can move on. Suggestions and improvements are always welcome, It was my first encounter with...

additional information from microchip site: Adress; = 000 I2C_start(); I2C_sendbyte(0b11010001); // MCP4326 address byte with READ command for ADC CH1 I2C_readbyte(); // Read Upper Data Byte I2C_Ack(); // Send ACK so ADC can send Lower data Byte I2C_readbyte(); // Read Lower data Byte I2C_Nack(); //...

Hello boys and girls ... Question ... Who has experience or can help me to get a MCP3426A0. 16 bit i2c working I can not get it done. (not even after much struggling and trying) :oops: The i2c FC example do not help me. :( Ecio works ..... The display works ... I2c MCP3426 ADC not yet. connected as ...

People ..... After some initial problems, I can announce now that uploading to the arduino_uno succeeded!!! :D I want to thank everyone for their time and wise words. For those who still have problems, see also http://www.matrixmultimedia.com/support/viewtopic.php?f=68&t=797 Thank you. regards, Rene

shame ...
It does not matter what I try, it really does not upload the hex file...

Strange that it does not work within "flowcode".
The Xloader program also uses avrdude, and that works well.

what could be wrong?

I would once again start all over again ....
now with more success

Yo...

I did send a report to avast...

I switch off avast for 10 Min. ...
And now FC works fine...

Besides the comunication with Arduino UNO.
This still does not work ....

Tomorrow more .. and hopefully success

Thanks...

René

Hi .... Today I received the professional key V5 (AVR) by e-mail. :D After the program was downloaded, I try to install FCv5 AVR but, Avas t comes with a malware warning after completing the licebtie key REGME.EXE contains a virus (malware)... Then I can no longer enter a key, and I'm unable to acti...

Hi Boys en Girls.... I make use the 16F628A. and it seems that with FC5 the delay's not work anymore ... I have a serious time problem :( oscillator set to: INTOSC I/O Clock Speed ​​4000000 hz selected .. as additional setting in C at the start of program >>>> set_bit (pcon, 3) To force the 4MHz clo...

Hi, There is some progress!! Not initially. But I did install flowcode again, in a directory without spaces in the name. I once had a similar mistake with flowcode for PICs, and you never know. Avrdude continues .. but stop at some point yet again. Only the RX led lights up on the Arduino board. see...

To bad!
I did as you described ..same result.
Avrdude will not upload ...


Still sugestions left?

René

Hi ...
Here I am again ...
Sorry it took so long, but I just had other occupations.

The fact is that it still does not work with me.

The requested data:
  avrdude.exe 14-3-2009 --- 274 Kb
avrdude.conf 5-3-2009 ---- 471 Kb


cheers

Rene

Too bad it still does not work ... :( the "uno.fcs" file loaded and again this gave a new error .... by location: C: \ Program Files \ Flowcode (AVR) \ v5 \ Tools \ MX_bats \ avrc_arduinoA.bat Do you use a different *. Bat file? I see the capital A stand behind arduino? :? But when I delete this , ...

Hi ... Thanks for your efforts so far. :D The LED on the Uno flashes It worked with the Xloader It worked with the Arduino sketch tool 1.0.4 But not directly with flow code ... :evil: Are you able to upload it directly from Flowcode? If so what are your compiler options, location and parameters? my ...

Hi Dazz .. Thanks for your response. I've tried it, but get the following messages. If I opens your project file I get the message: Unable to create microcontroller Arduino Uno R 3PDIP PWM as the definition fie Arduino Uno R 3PDPIP pwm.FCD is missing or corrupt [0x201] Is this because i use the free...

Hello boys and girls ... I want to do some programming with the Arduino UNO R3 ! Question: What do I need to Program in that thing ? :?: I have already : Flowcode 5 avr downloaded (free) (I buy, if suitable) Arduino Uno R3 Do I need more? Will someone explain to my what to do? thanks.... Rene

I have been searching on several sites, i give up now. :? I'm looking for a Pic with a 12bit ADC, internal ref + and an internal clock. Memory and speed not really matter, must be supported by Flowcode v5 Is there a more simple tool than Microchip product selector, so you can see whether it is suppo...

Martin, I'm having NO problems with the 16F1937 any more With the modified file 'PIC_CAL_ADC.C " I succeed in FCv5. Now I can use the internal REF. voltage without the chip crashes or freezes. Depending on the required ref, set fvrcon to 0x81, 0x82, 0x83 I set fvrcon= 0x81 before every call of the A...

Solved....

I found my answer over here...

thanks to all

Hi Martin, Yes, was right though. Uppercase and lowercase, I should have known. Now I'm one step further, compiling works ... thanks. I like to built a milli-volt meter with minimal parts..(no opamps) only one chip and a display, it should be possible with this PIC, right? With the Internal ref at 1...

Hi all, I want to use the fixed 1.024V reference of the 16F1937. The chip specifications tells me to set bit 1 and bit 7 of the FVRCON register.( if i'm correct with this) But when I use the set_bit(FVRCON,0) and clear_bit(FVRCON,1) the compiler generate a error something like "left operand must be ...

A ha...out of spec.. :oops: All I need is a simple voltmeter that shows a input 0-1000mV on a display. 0-5 Volt succeed ...with no problems I've ordered a 16F1937... This has an internal ref voltage of 1.024V .. :wink: How to use this in flow code, I still have to find out. Has anyone experience, id...

Hello, I have a 16F887 with an LCD display which is now a 0-5 voltmeter and this works fine. But now I would like to make a voltmeter that can measure 0-1000mV. How do I do that??? I know something as Ref+ can be used by example to offer pin5 1.024 volts ... but to me it does not work. Does anyone h...

Thanks Benj... I try to set and reset the pcon bit as you described , the clock speed of the pic increased and decreased with changing bit status... :D Now i know how to set some bit in C-code (I like to know more about C with Flowcode4. what will you recommend me) I'll try to bitbang a PWM fore som...

Hello, I have a little problem with a 16F628. The PIC has an internal clock of 4 MHz or 37kHz .... But all my programs designed with flowcode4 and tested on the EB006 will run the chip at 37khz. How do I get this chip running on 4MHz ? According microchip registry PCON bit 3 OSCF: INTRC / ER oscilla...
