Learn to use microcontrollers to control real projects. Come prepared to build. Everyone participates. Check each month's schedule for the night's project and necessary supplies.
Embedded Workshop - TONIGHT - Wednesday, October 22nd from 7 PM to 9 PM (Every Month on the fourth Wednesday) in the Hands-On Classroom
The Embedded Workshop for October will be on interfacing a SPI (Serial Peripheral Interface) device to an Arduino. SPI is used for displays, sensors and all sorts of devices. Typically, SPI devices have some smarts of their own. The device I chose is pretty cheap. It will be available at Tanner's (across the street) for $2 and it looks good. It is a vacuum fluorescent display with one line and 16 characters. Jimmy is going to hold 10 of them for our class. I should probably tell you that we were going to use small graphical LCD displays, but they did not arrive in time. I just started interfacing the VFD displays today and they are not quite working. I expect I will get it going before Wednesday evening.
If we have time, I'll also help people get other SPI devices going.
Last month, we interfaced to an i2c temperature sensor. SPI is the other fairly common data link used in embedded peripherals. SPI is more common, and something embedded developers will often run across in interesting projects.
The Embedded Workshop will be held at the Dallas Makerspace at 1825 Monetary Ln #104, Carrollton, TX 75006. This is near I-35 and Valwood. It normally runs until about 9 PM, although instructor Ralph will stay later than that to answer questions and help everyone finish.
I look forward to seeing you there,
