I would like to receive analog(current) values thru CN10/CN11 to the STM32F10C Eval board, process them and output the values to the putside world thru a modem.
I am looking the ADC example given in peripherals library.In the readme.txt, I could not understand the lines - Connect a variable power supply 0-3.3V to ADC Channel14 mapped on pin PC.04 (potentiometer RV1 on STM3210B-EVAL and STM3210E-EVAL boards)
Where are the positive and negative lines from the variable power supply connected in the board?
How can I use the on-board Potentiometer for this example?
Any help is much appreciated.
I would hazard a guess that there is a 'patch' area on the board that has a connection to RV1 and another to 3.3v and you should connect these together. This will give you a variable voltage at PC.04.
Note that this is all an assumption from what you have posted, you need to study the schematic for the board to be sure. Note also that this will not let you measure current, only voltage.
Note that this is an ST product - not a Keil product!
The STM32F10C Eval board is provided with a printed manual that includes the schematics. The manual is also available for free download from the STM32 documentation page on the ST website.
Thanks for your inputs.
Yes, the board is ST and I have gone through the manuals and data sheet.But I could not extract the actual hardware connection for running this example. In Keil installation folder, I do see similar examples as of ST peripherals library. This ADC example is in C:\Keil\ARM\Examples\ST\STM32F10xFWLib\Examples\ADC\ADC1_DMA.
Hence I thought,I could get help from Keil support.
They are not just "similar" - they are the same!
Keil are simply providing a verbatim copy of the ST Firmware Library - complete with all the examples.
The STM32 documentation page is here:

The STM3210C-EVAL evaluation board schematics are here:
www.st.com/.../stm3210c-eval.zip
The schematics are prevented as a PDF document - you can just search for "RV1"...
Should, of course, be "...presented as a PDF document..."
