Hi, I'm using a mikromedia7 for STM32F4 board. Using the USB library from LibStock I was able to successfully write files to a USB flash drive. We've made a few small tweaks to the program in recent months, and just noticed that as soon as you plug in a flash drive, the program stops. On the debugge...

It looks like some event happens about five seconds after powerup/reset. Before this, it looks like everything works. Afterward, the system either hangs or doesn't. If it doesn't, then it seems to be fine from then on. I've noticed that with one USB stick, the system hangs almost every time, where w...

It looks like I2C1 is used for the touchscreen and no other I2C is used. I2C1 is also connected to the accelerometer, but I see no evidence that the accelerometer is ever accessed.

So I now have the code opening files, writing data, and closing the files. That all seems to work nicely. The problem now is that when I plug in the USB stick (or reboot with it already plugged in) the program usually (but not always) crashes a few seconds later. If it doesn't crash within a few sec...

I am using mikroBasic Pro for ARM, version 6.1.0. But I don't think the compiler is the problem. I tried several hex files that were known to work, that haven't been compiled in years. None of the VTFT sample projects work, and they all used to. I updated VTFT several years ago, and all the hex file...

Update: I found a copy of mikromedia STM32F4XX USB HID Bootloader v130.hex and loaded it using the mikroProg. Now the device is recognized and mikroBootloader works! However most of the programs I try still don't run. My latest modified code from my old project runs, and a version of my old project ...

I think I must be missing something simple, but I just can't see it. I pulled an old Mikromedia board off the shelf for a new project, and when I program it using mikroprog, I just get a blank screen. I tried loading the old project's hex file, and get the same result. I tried the Calculator and Hel...

Excellent!

It's now displaying the directory, as long as there's nothing with long file names.

Thank you.

Reading the help file, it seems like the Host_MSC project is missing calls like the following: USBHost_RegisterClassRequestsHandler(USBHost_MSCClassRequestsHandler); USBHost_RegisterClassHandler(USBHost_MSCClassHandler); Can the demo work without these callback functions? If not, how do I implement ...

HI,

Sorry it's been a while, this project got shelved, but it's back now!

Attached is a zip of the project. I haven't gotten any further really, after spending another day on it.

Thanks in advance for your help!

Hi, My goal is to use a USB stick to store data from my application which runs on MikroMedia7 board. I started with the Host MSC example for STM32 from the USB_Host_ARM package from LibStock. I tried to get the example running with minimal changes to make it run on the MM7 board, as it was written f...

Hi Marina,

I use VTFT to generate my screens, then move to MikroBasic to generate the code that runs my system.

If I get a new font into the Basic project, I can use it in basic, but that does not mean I can use it in VTFT, as far as I can tell. How can I use the new font in VTFT?

Thanks.

Don

Hi,

Can GLCD Font Creator import fonts from VTFT, and export them back?

Does it support Basic Pro for Arm? The web site doesn't say it does.

Thanks.

Don

Any news on this? It's been over 5 years and it still seems to be a problem. I couldn't find any fonts that are fixed width on the actual screen, though some are in VTFT.

Hi, I have an application where I want to use the battery to keep the clock running while the main power is off, and I'm not sure the best way to do this. USB will not be used in this application, only for development through the bootloader. The problem is that if USB is not connected, the VCC-SYS i...
