Hey Guys,My name is Fernando and I am from Brazil.I am working on a litle project to read a PT100 temperature sensor using the MCP3201 after some aplification and filters. I have attached the datasheet for the MCP. I am having problems to build a vi just to read what the MCP3201 is giving me through the SPI. My knowledge of programming, bits and bytes is kind of null.I have read other posts but each has some little diferences and I couldn't receive any data.From what I understood the MCP3201 needs to have is CS at low to provide the info. But it seems that the SPI Send and Receive is not changing the pin to high or low as required by the MCP.PT100 Temperature SensorMCP3201 - ADC 12 bitsArduino DuemilanoveI am using the pins as follows:Pin 10 - CSPin 12 - MisoPin 13 - ClockSPI Bit order - MSB FirstSPI Mode - 0SPI Clock Divider - (I got some questions on this) The datasheet says 1.6 Mhz and the arduino is 16 Mhz. The options are 2, 4, 8, 16, 32, 64, 128. Should I include 10 on the code?I really don't understand what is the input on SPI data (SPI Send Receive) that is required to change the CS(pin 10) from high to low. I can add a constant, but I couldn't figure it out.Do I have to make changes on the Interface Code? Or will it work on Labview just setting up the correct vi?Can anyone help me?I will attach the vi that I am working on asap.Thanks in advance.Fernando

Just use the "Join Numbers" VI.

Fernando did you manage to solve your problem. I have a similar AD MCP 3208, and I have problems to.How did you format the send command?

Are there any more updates on SPI? I am getting ready to try with the MAX6675.

Anyone got this working or tried and failed?
