I'm new to TI products, but I purchased a CC1110 evaluation kit and was very impressed with the performance. I want to prototype a solution based on the reference design for the evaluation kit, but I'm looking for advice regarding code development. Are there solutions that don't involve IAR Workbench? I don't like investing in tools for prototypes that may or may not see the light of day. I have an older C compiler for the 8051, but I don't know if I can use it for this, just looking for any advice on how to kick off without investing thousands of dollars.
