Re: V9 can not register on new site.

Use the credentials you use for your Matrix account on the main website, not the forum. That works for me. Same credentials work for the V9 forum.

Re: rtc and i2c LCD(backpack)

We could, however forum members do not write school assignments for students. That is an official policy.

If you suggest how you want to solve this we can provide feedback and help you if you get stuck.

So how would you approach this?

Re: Non Technical Question regarding FC7

Keys for old versions are not available for online purchase afaik. You will need to contact sales. However fc9 will be released in a few days (if everything goes according to plan) and at that point fc7 will no longer be supported, so do you want to spend money on it?

Re: (re)programming a PIC over USB

A bummer? Having software control of the oscillator is a feature. At allows you maximum flexibility.

What are the oscillator settings in your flowcode project?

USB with 1 MHz clock? That does not sound like a setting that would work (from memory).

Re: (re)programming a PIC over USB

Keep in mind the boot loader sets the oscillator and you might not be able to change those settings in your code. Try matching the boot loader settings in your program.

Having issues posting on the microchip forum does not mean you should post messages unrelated to flowcode on this forum.

Re: iC2 2004A from Flowcode 7 via ATMEGA32 FAILURE

Resistors as a rule of thumb 4k7.

The same contrast behavior is something I’ve seen with perfectly working displays so isn’t necessarily an issue.

Re: iC2 2004A from Flowcode 7 via ATMEGA32 FAILURE

Are there pull up resistors on the I2C lines? Those might be present on the display module, however if there aren’t any yet you will need to add them to your hardware setup.

Re: (re)programming a PIC over USB

To search for chips you can use the Microchip parametric search . With the right parameters you should find the 16F1459 which meets the requirements. A quick google for USB boot loaders suggests Microchip provides code for one (HID boot loader). To use the result with Flowcode you will need to provi...

Re: Cannot compile to HEX with Pro lisence

The naming of PIC devices with PIC, PIC16, PIC24 and PIC32 when there are 8 bit pics called pic16f<whatever> which is a PIC, not PIC16 doesn’t make things easy for the non expert users. May-be Matrix can reconsider the naming of the chip packs?

Re: Re-position code start address not working

DoNothing does what the name implies: nothing. Adding arguments won’t make it do anything else, it still does nothing.

You need to modify the compiler settings which in FC8 does both compilation and linking of the code.

Re: USB Slave on PIC

I get your point. It's interesting that you should bring up PCB design software. I am a CID certified PCB design engineer. If the software doesnt have a component I just create one as required. Which is pretty much what I want to do in FC. That is pretty much what I’ve done for a couple of customer...

Re: USB Slave on PIC

The problem i am finding with FC right now is that it if you arent using the paid for components, you cant really do much with it. There is a lot you can do with Flowcode. However it is unrealistic to expect to be able to implement every use case with it. There are just too many different microcont...

Re: USB Slave on PIC

For an USB drive you need usb mass storage. It might be possible to implement that using usb slave, but I don’t think that will be trivial.

Re: Signed/Unsigned int property

Hi Martin,

That screenshot is in Flowcode, not on hardware... I agree it would be better to limit the size for values to 16 bit on display, but I am still curious what happens if you use this variable on hardware. My money is on it being 16 bit...

Best regards,

Re: Semiduplex asynchronism serial 10bit

This is just a difficult way to describe 8n1, so you can use use the regular uart component with 8 bits, no parity and 1 stop bit.
