Re: Internal osc PIC12F683

Chinese proverb: One picture = 1000 words
In this case Two pictures = 2000 words. So, here two pics of what you have to do.

Re: Internal osc PIC12F683

Hello MJU Yes, you can use the internal RC module of P12F683 and to have available 2 more pins for I/O. In FlowCode "expert Configuration screen" you must select: Oscillator = Internal RC No Clock . In the same screen you could select: Master Clear Enable = Internal . Thus you could have 6...

Re: Rotory Encoder and PIC

The last program what tested on hardware with an optical encoder. It works at 500 pulses/s. There is no need to debounce because it is an optical encoder. On the thread: http://www.matrixmultimedia.com/mmforums/viewtopic.php?f=26&t=8773 It is a mechanical encoder so you need a debounce. Here is ...

Re: Philips RC-6 protocol

Hello MJU I haven't tried never the Philips RC-6 protocol and from the few things that i know about it, there is a main issue of compatibility regarding modulation. Although in both versions, RC5 and RC6, data are modulated with the use of Manchester coding (Bi-phase coding, i.e. each data bit is sp...

Re: Compile message: Config8L

Hi MJU, Thanks for sending me the registry files. I have now been able to determine the reason for the message and give a workaround. The problem is caused by 2 different versions of the PPP programming software sharing the same location for their registry data. I can offer two workarounds. The firs...

Re: Simple chip settings?

Hi It does look as though the simple screen has been removed. If in the advanced config screen you click the options button at the bottom, the PPP options screen opens and the use simple config is grayed out. This is how you would get back to it in FC4. So I imagine Matrix have removed that for some...

Re: Project report: expand comments

Hello. Do you mean in the generated images of each Flowchart? No, there isn't anything to expand all at once I'm afraid. If you hold down 'shift' and double click on the icons annotation it will automatically resize to the full size, and there is a global setting to automatically create new icons wi...

Re: EEprom erase

when you program the eeprom gets a 0xff write to all locations, if you veiw the eeprom with a pickit i beleive you can copy to clipboard and paste it back in then program, i just create a small program and send the eeprom out to another pic chip via serial into its eeprom, if your curious i could sh...

Re: EEprom erase

Does this mean that the Eeprom is being erased with programming?
As Brandonb said, programming chip erase EEPROM too and the power-up value of EEPROM is 0xFF. But there are ways to save your data in EEPROM before re-program like as said by Brandonb in different chip or external EEPROM.

Re: How start a project

Re: How start a project

Hi. I am a big fan of commenting code. A good test of how readable a project is is if you can leave it 6 months, come back and pick it up again. - Macro comments should always be provided to give an overview of what a macro does - never cut corners here if you want to maintain the code. - Comment bl...

Dear MJU,

I'm sorry, but the boolean must be set to true (=1) at the first call, instead of false (=0)

Kind regards

Re: Software reset PIC

Hi you could use the watchdog timer , if enabled you have to regularly check it, so you would let it time out where you wanted a reset to occur (search the forum as there are some good posts on using it, another way would be to use a sparepin and use it to drive the mclr pin when a reset is required...

Re: Software reset PIC

Hi
Ive used a C command to restart the device in the past.
Just put a C Box into the flowchart at the point you need to restart and enter the command reset( );

Though I expect its similar to asm("reset");

Re: Which AVR to start with?

Hi I cannot remember if the programmer cam with a device or not. I tend to use either the ATMEGA324P (40pin) or the ATMEGA 328pu (Same as the arduino uno) for basic experiments. Easiest intro to AVR way is an arduino, though not as versatile as the Matrix programmer, which is a nice board. Comes wit...

Re: Which AVR to start with?

Hi
Start with a cheap arduino using a 328pu chip, Or buy some 328pu chip with the arduino bootloader built in as you only then need a few components to get it running, there are advantages and disadvantages to doing this, like you can only have a 16mhz xtal, but the fuses are protected

Re: Problem: import V5 in to V6

Hi MJU, I know there is going to be a patch released soon with will cover amongst other things various V5 to V6 conversions. For instance when you have a RS232 component, in V6 you need to add a RS232 initialise which was not necessary in V5. So if its RS232 comms producing the error it could be tha...

Re: How to use the scope?

Morning. Yes, I agree this could do with an interface. The scope and console were added to support components - idea is a component adds whatever output it requires. I will look into this and possibly add some UI to the front end of the scope. In the meantime, here is a component that allows up to 4...
