Assemble and test 2nd Tiva-C + Radio/Peripherals board #47

Closed usaguerrilla closed 8 years ago

stcarlso commented 8 years ago

Assembled; testing still needs to happen. May be able to close it this weekend.

I have found out that I was given a Stellaris LaunchPad instead of a Tiva-C version. Therefore, the code will not run. Do we have another Tiva?

Scorillo47 commented 8 years ago

I thought TIVA is just a brand rename of Stellaris - should have the same underlying SoC.

I think Pavel has a TIVA

BTW - if there is a hardware difference between the two, what would it take to port the code to Stellaris?

I have a bunch of Stellaris boards but I have no TIVA-C

On that page, it states that the Motion Control PWMs are new to the Tiva from the LM4F. The document at http://www.mouser.com/ds/2/405/lm4f120h5qr-124014.pdf lacks section 20, "Pulse Width Modulator (PWM)", so this module is unavailable on the LM4F Stellaris LaunchPad. This is a critical feature required for the APRS module, so we must use the Tiva C version.

Got it. I will order one TIVA

This has been fixed.
