Re: reading a voltage with a SuperPRO

A quick picture will show you what is happening with the meter. meter.gif The meter looks like a 10 MegOhm resistor or greater, so the resistor divider is 10000000/(10+10000000) or basically 1 When you add the 3K resistor the 10 MegOhm is in parallel, which is 2999.1 or still basically 3K But you wi...

Re: looking for an ARM7 board

The ARM7 will be around for a while, but many of those chips are now 10 years old.

The industry is now pushing ARM Cortex M0,M3 and M4 in this product range. For good reason, they are faster, cheaper, and all that ...

Re: Quadrature

PCLK is the peripheral clock. In the PROplus and SuperPRO this is 24 MHz (1/4 of the CPU clock)

Re: RS232 failure to communicate

I know you're unhappy with the BASICchip setup, but I'm still trying to figure out what your actual serial connection was. You say a ChipKit MAX, which I assume means an Arduino like board (chipKIT Max32), but if you are trying to share the serial port with the connection to the PIC there are going ...

Re: Arduino Sketch support

We are ready to have people start porting Arduino Sketches to our C software setup THIS IS STILL A WORK IN PROGRESS, but it actually looks like we are ahead of the Arduino community a little on the ARM support. We have GPIO interrupts working there, at least internally Any if you want to give it a t...

Re: RS232 failure to communicate

If you are still seeing *** Uart chipkit 19200 baud *** Serial to Usb Then the driver for the cable is still inserting characters into the communication between the PC and the BASICchip, and that is confusing our software. So I'll have to conclude that the ChipKit USB converter is NOT compatible wit...

Re: RS232 failure to communicate

That *** Uart chipkit 19200 baud *** Serial to Usb Is being inserted by whatever driver/software you have controlling the ChipKit USB link So you're going to have to disable that driver/software to have it run with our code. We don't really expect extraneous stuff to be inserted while we are using t...

Re: RS232 failure to communicate

Just for grins I copied the BASICtools to a network drive on a Win7 system and that works for me, though I remember seeing issues before, it may be limited to XP setups. I've never had any issues on USB drives. Where is your %temp% directory? So its back to checking your serial connections. What did...

Re: RS232 failure to communicate

Is your E drive a network drive?

Tcl has trouble with network drives, maybe I need to figure out a way to detect that and flag it.

Re: RS232 failure to communicate

I can't explain why what you see is different, so the other questions would be-- What OS are you using? (we routinely are running Win7 or XP) What FTDI driver are you using? (we are now using 2.8.24 -- available from our installer in Windows Driver folder or check http://www.ftdichip.com for the lat...
