PIC18F46J50 USB HID and SD Card 4 Channel Datalogger

[internetuser2k12]

Hello!

Here is my modified project PIC18F46J50 USB HID and SD Card 4 Channel Datalogger running at 20MHz. Code written in miroC Pro 5.6.0.

put the mcHID.dll file in windows\system32 folder and run the vb.net setup.exe file. After install run the installed vb.net app.

Start proteus simulation. (proteus file datalogger.dsn is inside the .rar file)

In the vb.net app click different tabs to see the progress bar (temperature) vary depending upon the tab (Channel) selected.

To create .mmc file WinImage was used.

Report bugs.

Screenshot attached.

I am getting some "[MMC CMD] Command Unsupoorted" warning in Proteus. If anybody knows how to solve the issue, please mention it.

I have 18F4550 chip. will it work for 18F4550? what should be the configuration bits/word?

 

[Jayanth_Devarayanadurga]

Yes it works with 18F4550 and also 18F2550.

Sorry, I don't have the project files now.

Great sharing can i use .dll file in C#.

 

[milan.rajik]

@embpic

mcHID.dll only works with Visual Basic.Net. You can't use it with VC#.Net

You can use easyUSBHIDNetClass.dll which works with VB.Net and VC#.Net

I don't have the project files now. If anybody needs sourcecode then mention it I will make a new project and post it.

internetuser2k12... How do you can resolve the problem of simulation in Proteus? In many examples when the software read Mmc_Fat_Inic() the Proteus don't work... your code work very well!.

 

[milan.rajik]

If the SPI pins of MCU has additional functions like ADC, etc... then disable them and make the pins digital IO then MMC_Fat_Init will work. I have used winImage to create .mmc file for Proteus. First create .IMA file and then save it as .mmc file for Proteus MMC Card.
