Security, Security, Security...
Hello there folks,
it is a holiday season all around the world but we are not slowing down. It looks like Q1 will bring our BASIC-programmable products several important security-related enhancements. Here is just some stuff we are working on: additional security modes for Wi-Fi (cause WEP is cr**), SSL support, and protection of customer’s Tibbo BASIC application loaded into the module.

SSI does MAXIM RTC
Yet another application for our SSI object. We have successfully used our SSI to interface with the DS3234 “extremely accurate” SPI RTC.
Here is the code:
'------------------------------------------------------------------ io.num=SPI_CS io.state = HIGH io.enabled=YES io.num=SPI_CLK io.state = HIGH io.enabled=YES io.num=SPI_MOSI io.state = HIGH io.enabled=YES 'setup SSI channel...

SSI does Microchip Port Expanders!
G’day folks,
it hasn’t even been a week since we published our SSI object, and we already found an application for it. We used the SSI to control Microchip’s MCP23017 16-bit port expander.
For those of you who never tested this, Microchip port expanders are I2C or SPI ICs that give you 8 or 16 I/O lines. Add something like this to our (relatively low-pin count EM1206) and you...

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...

TIDE = Speed (re: Modbus)
Case in question: our own in-house test of an energy meter with RS485 interface running MODBUS protocol.
One of our potential Customers wanted to us to create a small Tibbo BASIC app that would query the meter and show the data on a simple HTML page. Two hours later (spent mostly on connecting and arranging things) we had a working application prototype. The source code is published here.
We...
