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.

Hi I am using the MPSSE I2C drivers over a USB FT232H device, communicating with BMP280. When I read the BMP280 device ID, it is supposed to return 0x58 but the DeviceRead vi returns 0xFF. I have used a logic analyser and can confirm that the device is actually sending 0x58, but the output from the read vi is 0xFF. Has anyone had this same problem, or can anyone suggest what might be the issue? Thanks Arj -
I have a question.... The MPSSE I2C driver works great. But it does not have a Write-Read dll in it. Calling the WriteDevice and Read Device separately in LabVIEW is generating considerable delay ( ~1ms windows scheduler + labview ). is there a combined DLL for Write-Read. currently I am able to reach only about 400 samples per second with my ADC. I want to be able to use upto 10ksps. Is there any other way to reduce this delay ? Thanks for the help.

There it is... finaly... Because the code given in the FTDI web page is not convenient, not working and haven't been developed by real LABview programmer, I decided to create a library for the I2C. a version for SPI will come soon. This library is free to use. If FTDI want's it in ther site, I do not allow you to publish it since you didn't help any of your customer with LABview. but of course feel free to publish this link.
