SPIDriver: the Tool to Control and Monitor SPI Devices
SPIDriver is an easy-to-use tool for controlling SPI devices. It works with Windows, Mac, and Linux, and has a built-in color screen that shows a live logic-analyzer display of all SPI traffic. It uses a standard FTDI USB serial chip to talk to the PC, so no special drivers need to be installed. The board includes 3.3 and 5 V supplies with voltage and current monitoring.
SPIDriver comes with free (as in freedom) software to control it from:
- a GUI
- the command-line
- C and C++ using a single source file
- Python 2 and 3, using a module
Features
- live display shows you exactly what it’s doing all the time
- sustained SPI transfers at 500 Kbps
- USB line voltage monitor to detect supply problems, to 0.01 V
- target device high-side current measurement, to 5 mA
- two auxiliary output signals, A and B
- dedicated power out lines. two each of GND, 3.3 V and 5 V
- all signals color coded to match jumper colors
- all signals are 3.3 V, and are 5 V tolerant
- uses an FTDI USB serial adapter, and Silicon Labs automotive-grade EFM8 controller
- also reports uptime, temperature, and running CRC of all traffic
- all sensors and signals controlled using a simple serial protocol
- GUI, command-line, C/C++, and Python 2/3 host software provided for Windows, Mac, and Linux
Specifications
- maximum power out current: up to 470 mA
- signal current: up to 10 mA
- device current: up to 25 mA
- dimensions: 61 mm x 49 mm x 6 mm
- interface: USB 2.0, micro USB connector
SPIDriver is on Crowd Supply until July 13th, and costs $27 for the SPIDriver Core (no LCD), or $57 for the complete SPIDriver Expert. Orders should ship in August.
