Re: AD Conversion Speed

Gordon So you are saying that the ~72 kSamples/s of the MCP3002 on the Gertboard is not achievable? Another question: for multichannel A/D is the sampling rate divided between the channels, or can I achieve 200 kSamples/s per channel on the MCP3002 (supplying it with 5.0 V, and using a level shifter...

Re: MCP3008 SPI Inaccurate readings..

Hi all

I'm trying to make readings as fast as I can with the MCP3008. At first I tried the spidev library for python, but I only could do ~1400 S/s. Is there anyway to do it faster, i.e., go to the limit of the MCP3008? If someone have an example code I'd appreciate

Thanks in advance.
