Illustrious DSP Group Members: Has anyone actually used the freebie Motorola C compiler that comes with the EVM kits to successfully implement a program on an EVM board? Analog Devices support for C isn't tremendous, but it is one WHOLE lot better than Motorola. According to official Motorola Tech Support (in CHINA no less!) there are NO demo programs written in C for the EVM boards. Duh.......... I have several EVM boards ... 56002, 56303, 56307, etc. ... and have exclusively programmed in assembler so far. I would like to have the convenience of being able to do some quick and easy testing using C source code. I just haven't had time to mung through the Motomire to get even a primitive C demo running. Currently, I'm focused on using the DSP56307EVM. What I plan to do is just write a dumb trivial demo to run a "main" loop and call a couple of functions to initialize and set the TI0 timer (tied directly to a LED) to blink at a parametric rate (nominally 1 second) with a parametric ON time (nominally .1 second). Once I get this far, I should have a decent template for further experiments, especially some generic DFT/FFT and COM utilities. One additional question ... the 56307EVM supports FAST async serial ... does anyone have any experience trying to communicate with a PC host COM port at 460 kBaud? I am most interested in the Windows software aspects (LabWindows/CVI) ... I already know about cable capacitance for RS-232, and am using RS-485 (differential). Thanks for any assistance or comments ... All the best, and ENJOY! Art Du Rea Systems Engineering Consultant Knoxville, Tennessee, USA
