µTasker general / Re: MCU Recommendations

Hi,

I am moving forward with LM3S8762 Eval kit just get my bearings.  I'll switch to another chip for actual development.

It may be of interest to others, I discovered an apparent small "secret" about CodeSourcery for Luminary.  You can get a full license for only $199!   It is restricted to Luminary ARM M3 devices, but otherwise is generally full featured.  They did remove a few features such as the code simulator and support for 3rd party JTAG, but it works with the FTDI JTAG included in the 8762 eval kit, so I'll try that out.    Otherwise the $399 license works for all ARM families.

Thanks again for all good comments.  Now on to the real work...

Thanks to all for excellent comments!

Our project has just taken a new turn and we now require a MCU with two CAN ports as well as the Ethernet-Phy.   This more or less forces us toward the Luminary parts, so I guess I'll dip my toe in and see how cold that water is.

I ordered up a LM3S8962 Eval kit just to get a feel for all.   Mark: I'll need to get the uTasker kit for that.

I am planning to try out the CodeSourcery path, as they only require $400.

Let me know if anyone has had any bad experiences with CodeSourcery.

Thanks All!

µTasker general / MCU Recommendations

Hi All,

I am new to uTasker and so far it seems to be a very impressive package!  Nice job!

We are starting a new product and I am curious if anyone has recmmendations for a MCU family.

I am doing the evaluation using the Coldfire M52259DEMO and was originally targeting the M52235 device with the built in PHY.    I very much prefer the single chip solution, with internal flash/phy etc.

I also see the LM3SXXXX Stellaris (Luminary) also include the PHY and at first glance seem like very capable devices.

Does anyone have any overall recommendations, including the devices, performance, software tools, debuggers etc?

Thanks all,

SteveT
