I have had good luck with the Laipac TRF-2.4G. You can get them from Quality Kits.

These modules are on the (Supposedly) worlwide licence free frequency of 2.4GHz and can transfer data up to 1MB/s.

I have noticed that no one has replied to you (And probably won't). Unfortunately, you have posted your query to a BASIC forum (and also for Microchip PIC's). It is fairly unlikely that anyone here could help you. All I can really advise is that you find a forum for your particular microcontroller a...

I don't have a keypad but I have looked through your code. You have declared "kp" as byte type but, according to the MB manual, the keypad_released function returns a word type. You may be overwriting memory causing strange results. Again, you declare "cnt" as byte and then use it as a parameter to ...

Just hook it up exactly the same as the DS1820 in the 1-wire example in the MB manual.

Note that the DS1990 does not have a Vdd connection so hook up the IO connection to +5V with a 4K7 resistor and to whichever pin on the PIC you with to use for 1-wire comms.

Your problem is in the loop where it is waiting for the temperature conversion to complete... j1 = 0 ' Wait for temperature conversion to complete while j1 = 0 Delay_ms(25) j1 = Ow_Read(vPort,vPin) wend You need to initiate a read time slot before you start reading from the DS1820 otherwise the loop...

You may like to check into the FTDI chips/modules . These things make hooking up your working USART based project real easy. They include royalty free drivers for Windows, Linux and MacOS. AFAIK writing a USB device driver is a bear but hook up one of these modules and you are good to go :wink: [/url]

Early Bird - I don't think you understand what Soft_Uart does. It is the MB way of bit-banging a serial port. You can bit-bang any pins you like without needing a hardware USART on the PIC. This is how it was done before PIC's had built-in USART's. These bit-banged pins can then be routed through a ...

I can see two obvious errors in your code. The first is your "endof" variable. You set it to 555 but as it is a byte type it can only have a maximum value of 255. Secondly, you create 65 character strings then try to write to the 66th character (Remember that the first character is located at positi...

I wonder whether the compiler is getting screwed up because "Index" is a byte type but the maximum value that could be used (300) exceeds the maximum value that a byte type can have (255).

Maybe you could try making "Index" a integer type and check?

It is up to your county's customs service whether you will be charged duty or tax. You will have to wait for a letter from your customs service. The tracking number you have can be taken to your local post office. They should be able to tell you if it is with customs or not. I know, in Australia, th...

PS As for those stepper boards, Steve mentioned: to do work but are quit expensive! The PIC board plus the stepper drivers IC are cheaper than those stepper boards (at least for 3 axis). True but I like the fact that they have been tested and debugged. If I can find something that does what I need ...

Well, that was wierd. I thought I had the latest manual but I downloaded the latest one just in case. When I first opened it, it had the same construct for Mmc_Fat_Assign as in my first post. I closed the file and re-opened it and lo and behold it changed to the way you have it. Just plain wierd. So...

Yep, I'm pretty sure it's 4.1.5.

You can make some pretty awesome boards in 100 x 80 mm. Maybe one day I'll upgrade but for what I'm doing, it's plenty.

I have to agree - Eagle is the way to go. I must admit that it was a bit intimidating at first but if you work your way methodically through the tutorial and manual you will soon grasp it.

All the others I tried (And I think I tried them all) were actually more difficult in the end.

I have not used the MMC Fat library but reading the manual I see the Mmc_Fat_Assign routine is described... sub procedure Mmc_Fat_Assign(dim byref filename as char[11]) But you are using it... file = Mmc_Fat_Assign(filename, 1) ' Create the file, if not found What is the second parameter doing there...
