Tutobot – Schematic and Software

Hello,

Our PCB is 99% finished, the others 1% is about the decoupling capacitors. SmartFusion documentation recommends the use of capacitor of several different values to filter different frequencies with a small resistance for each frequency. It recommends using capacitors multiple of 10, for example eight capacitors of 0,01µF, four of  0,1µF, two of 1µF and one electrolytic capacitor, to maintain a certain capacitance and resistance in some frequencies.

However, we couldn’t find anything about how to calculate the numbers of capacitors to use in our PCB. In the Evaluation Kit, seems that they tried to use as many capacitors they could fit near the VCCs of the µC.

We worked in the software too, finally programming the SmartFusion in Linux is working. We played with the UART.

This week, Gabriel and me, we will be developing the software, Thalita will be responsible of the decoupling capacitors and routing as this can not be divided in several tasks, but of course we don’t forget that we are a team :)

  • Congratulations. Don’t forget to detail the steps needed to program the SmartFusion from Linux. Feel free to do it on your another site if you wish (a blog, a wiki, whatever) and include a link here, if you don’t want the instructions to be drawn in dozens of posts.
