SSI Object is Ready!

Busy day here at Tibbo folks. We’ve just assembled TIDE V2.20.16 (see experimental build at the bottom of the page). This includes the EM1000 firmware and platform files supporting our new Synchronous Serial Interface object.

Do SPI, I2C, as well as custom clock/data interfaces using this new object. You get four independent channels, programmable bitrate, endianness, clock phases, etc. you have a total flexibility needed to work with RTCs, EEPROMs, DACs, ADCs, and other serial ICs.

With speed reaching 1.2MBit/sec, the SSI object gives you performance that far exceeds anything you were able to do with direct bit-banging using IO object. Any I/O pins of your module can be used as CLOCK, DO (MOSI), or DI (MISO) lines. Moreover, the DO and DI lines can be mapped onto a single physical I/O line, which is necessary for I2C.

Stay tuned for actual code examples. We’ve got some serial ICs we are going to try…

Note: this excellent Wikipedia article explains SPI modes 0-3.
