Good day all. I wanted to thank all of you that provided some guidance to me regarding the 'which chip to learn with' thread. Ultimately, I'd like to program a pic to drive a DSP evaluation module, providing both I and O functions. This makes the DSP module into a portable transceiver for weak signal modes. Also, it does not need a large and bulky PC to give it commands and display the waterfall output. The DSP unit I have in mind is the KK7P DSP module, seen at: http://www.fidalgo.net/~wa7gxd/dsp.html I'd also like to program a pic to read the boiling point of water and then indicate when the maple syrup reaches 7.1 degrees above that point for the purposes of making maple syrup. The boiling point of water changes with atmospheric pressure, so a calibrate mode is setting a reference in boiling water, then measuring the boiling point of the maple syrup until it boils at 7.1 degrees higher than water. I have a degree in Electronics and used to work in high tech as a Field Service Engineer for an analytical lab equipment OEM and as a Senior tech in the equipment engineering department for a semiconductor chip manufacturer. I also did a short stint inn ATE department (automatic test equipment). In ATE, they needed someone with rf experience-they had no idea that one needed to provide proper termination and coaxial lines in the chip test fixture--they would pass on the bench, but fail in the high speed ATE tester! Also, I've been a ham radio operator since 1971 and like to play in microwave and laser communications. If you are still reading, I apologize for the boring intro. From reading the responses, it appears that I need to decide whether to learn C or do assembler. On this one, I have no idea! Perhaps I should have asked the group about this one first! Does C cost more and give better results? I have no desire to program anything other than a pic, should I learn assembler and stick with MPLAB??? Would love to have some chatter about this issue.
