Re: i2c problem with TC74
Hi Enamul,
According to the message from juanlu the device ID is 0x48, why have you changed it to 0x4d in your code?

Jac

Re: i2c problem with TC74
Looking at the flowchart I've noticed two things:
1) After the read you are transmitting a byte (1). Why?
2) You are not sending a I2C_Stop after the transaction has completed.
You might want to check if removing the transmit and adding a stop makes any difference.

I would not connect a pot before finding a data sheet. VFDs tend to have software brightness control, not hardware.

Re: Dot Matrix LCD Display
Enamul,
It looks like a VFD (Vacuum Fluorescent Display), not an LCD, to me. The current is not out of the ball park for those displays.

Re: Enabling PLL on 16Bit chips
You are welcome.
It certainly looks like a PPP issue to me. Hopefully someone at MM will be able to solve this and release a fix as your current work flow works but is cumbersome.
Good luck with your project!

Re: Using Microchip's USB HID bootloader for PIC18F4550
You need to tell the linker where the code should start. This can be done by adding "-rb 0x1000" to the linker parameters (assuming the HID loader uses memory 0-0xfff which a quick google search suggests)

You are aware the Vpp pin doubles as reset if not configured for I/O?
BTW in your diagram that pin is not used for measurement but connected to plus 5v via 100K.

As you suggest sending a special first byte to signal the start of a sequence is a good way. Preferably a value that does n...
