I want to design 4 four wire type RTD inputs on an ADuC7060. Show me the method to design the hardware and configure the software in the example RTD_PieceWise_Linearization.zip to work with four four-wire type RTD inputs like the example in document AN-0970.pdf
and one more problem when i make(F7) project RTD_PieceWise_Linearization on IAR(ARM 8.32.3) it gives error not defined __write.
Please show me how to fix this error
Hi,
The software example should work with the ADuC7060 evaluation board. The evaluation board uses a 2-wire RTD, but you can use the schematic of the evaluation board and the software example as a reference for a 4-wire RTD. I have attached the schematic of the evaluation board.
You can also check out the link below as an additional reference for a 4-wire RTD configuration.
For the software example error, can you check the Linker configuration file, if it is set to "ADuC7060.icf"?
Because the AD7124 ic is out of stock. So I still decided to use ADuC7060 to be able to buy goods on digikey or mouser.So I will be happy to help you with both hardware and software.

The most correct answer to fix the above error situation is
