The TI ARM Cortex-M4 EK-TM4C1294XL Tiva C Series Connected LaunchPad Evaluation Kit will soon become the preferred µP board for use as the RiceCNC motion controller. The TM4C1294XL uses a TM4C1294NCPDTI processor and a TM4C123GH6PM processor dedicated to USB host communication. The TM4C1294NCPDTI runs at 120 mhz about 50% faster than the TM4C123GH6PM used on the EK-TM4C123GXL and has significantly expanded input/output capabilities and is being introduced at a very low cost of $19.99 including shipping, USB and ethernet cables.
Ethernet connection is not yet supported. To enable the host software to communicate with the TM4C1294XL, you will need to install the MSP430LPCDC USB to serial driver. A package installer for this system extension is included in the disk image on the Welcome page.
To install and update motion control firmware on the TM4C1294XL, the system uses the open-source flasher utility lm4flash.exe. Because of licensing restrictions, you must download and install this tool separately on your system. A current version of lm4flash is included in the disk image available from the Welcome page. Follow the instructions in the “ReadMe” file.
