Hi,
Quite often I have to test/evaluate various SPI slave devices (sensors, expanders, etc) and I'm kind of sick of writing firmware in development boards for each of them.
If somebody knows a good and not too expensive development tool to send transactions to SPI slave, please tell me where to look at.
What I need in terms of features:
-a small board connected to usb, which acts as a SPI master and have standard spi connections (chip select, miso, mosi, sck) and a 5v output power.
-a good app to deal with this, which is able to define parameters of transactions (spi mode, speed, commands, what/how many bytes to send, how many bytes to read, etc). I need to perform simple transactions, not complicated or long ones such as flash memory block read/writes, etc.
Thank you.
