View File MPSSE SPI For a personal project, I needed to communicate between my computer and a SPI device slave device. So, I use a FTDI chip FT232h. I have adapted the library MPSSE I2C already available on this website to make it works for SPI. Warning ! VI are not 100% tested (especially Read functions), I provided it as it is.

Hello everyone, I have a small problem with SPI communication. I'm using NI USB 8452 module and LabView 2013 with driver NI USB 845x 14.0. As a first step I ran the example from attached library called "Atmel AT25080A Write.vi". The problem manifests as logic "0" all the time on MOSI and MISO lines. No Data transferred. CS and CLK works properly. I never use pull ups when using SPI but maybe I should? The question is did anybody meet the same problem while using this usb 8452 module? All 4 SPI lines connected directly to oscilloscope. Waiting for any reply. Thanks in advance.

hello, I try with the DAQ card PCI 6220 via the digital outputs LINE0: 2 (CS, SCK, SI), the digital potentiometer MCP 41XXX over the SPI interface to control. Unfortunately this does not work. I have a Vi to created the digital signals (picture) and another Vi to output (picture) them on the DAQ card. Phase and polarity of the SCK clock can I change. Unfortunately, the potentiometer can not be controlled with this program. Has anyone a Idea where the problem might be? Thanks JimPanse
