Hi All,

I have just started looking at using MPLAB X on my MacBook and noticed that Pic Basic Pro is listed as a tool suite (albeit being "Not Found" since it it obviously not installed on my...

Hi Darrel,

I realised that there was no dedicated USB RX interupt, hence my problem, but that is a very nice little workaround.

It works perfectly in my current setup and will no doubt be...

There is no specific timing requirement, the period is just the maximum Timer2 would allow.

I realise that I can of course just resort to checking for incoming traffic in the main loop and in...

Hi Darrel

Thanks for the reply, that certainly makes some sense. However I have replaced my tick timer routine with this one:


tick_timer:
USBSERVICE
USBIn 1, USBRXBuffer,...

OK, so obviously nobody has any thoughts so far but I have done a little more investigation and found out the probem lies with me using an interrupt to perform the reads...

I started from scratch...

Hi all,

Im having a little trouble using Darrel Taylors USB DT_HID "framework".

Apologies for the long winded post, but I want to give as much information as possible as opposed to the...

Bruce,

Thanks for the reply, looks like I have fallen foul of the curse of high level languages and forgotten all my assembler! I will have to go and brush up I think!:-D

Darrell,

Thanks...

Hi Bruce, thanks for the reply,

I use the following code and INCLUDE it in my main PBP file:

Hi all,

I learnt how to program PICs using Microchips C18. Its only since starting a new job that I have begun learning PBP as its what everyone else uses. The good news is that I like it and am...

UPDATE:

PROBLEM SOLVED!

In case anyone else has the problem I did - i.e. SHIFTOUT not generating any signals, here is how I solved it:

I should have followed the three standard debugging...

Hi all,

I am trying to write a PBP program to interface a PIC18F2520 to the MCP23S17 port expander (on the EasyPIC6 dev board).

If you don't know the Port Expander is an SPI device that adds...

Hi all,

I am trying to get a USB Project going but have hit a brick wall.

I am using Picbasic Pro 2.50a with microcode Studio. I used EasyHID wizard to create the template files and to check...

OK, I failed to realise that the location in flash will change (although it does make sense now I think about it).

Limiting to 256 devices is no problem, there will never be that many in...

Thanks for the reply Darrel.

I can see how assigning a serial number on the PC side could overcome this problem but you have to admit its a bit of a bodge and if you end up having to keep a lookup...

Hi all,

I had a search in the forums but could not come up with anything like what I am trying to do.

I am designing a device of which a number of identical units will be built. There is the...
