Tech Arts HCS12: DP256 vs. E128 - Jim Fiocca - Aug 11 12:49:00 2003
|
Hi, I'm getting ready to invest in an HCS12 board to be used as a robotic controller. I think I have it narrowed down to the Technological Arts Adapt9S12DP256 and the Adapt9S12E128. I know the E part is newer, but I'm having a hard time figuring out why it would be better for me. It has 1) less memory (Flash and RAM) 2) only 1 SPI (vs. 3 on the DP256) 3) potentially less PWM capability (depending on how the other timers can be used). I also don't believe I can use 3.3V mode since the I/O then isn't 5V tolerant. Am I missing something, or is the DP256 the way to go? Thanks, Jim |

My ground rules are: (a) does it look like it won't be obsolete soon? (b) does it seem to be popular? (e.g. enough sfwe tools/hdwe support available) (c) does it have about 50% more stuff than I think I need right now (memory, I/O, etc)? If you select a part with "too many features", you end up spending a lot of time debugging because you neglected to properly set up registers you didn't need in the first place. From what little I know about 'robotics control', I'd start with a D60. At 12:49 PM 8/11/2003 -0500, you wrote: >Hi, I'm getting ready to invest in an HCS12 board to be used as a >robotic controller.

Much of the newer activity on this list seems to favors the DP256. That is where I'd go. 607-656-2597 -----Original Message----- From: Jim Bacon [mailto:] Sent: Monday, August 11, 2003 2:21 PM To: Subject: Re: [68HC12] Tech Arts HCS12: DP256 vs. E128 My ground rules are: (a) does it look like it won't be obsolete soon?

Jim, Dave, DP256 or E128, that is the question. When making your decision, assume that there will be an E256 just around the corner. Also, consider the fundamental question - do you need CAN, now or in the future? Should you want CAN, go for the DP256 / 128 / D64. If you don't want CAN, and don't care about the cost of the MCU, you could also go for the DP256. However, if you do care about the cost of the MCU, and don't need CAN the E128 would be your best bet. Whilst this part _does_ run down to 3 volts, you can run it at 5 volts, like the DP256. The only other comment I'd make is that the E-family has our new BDM interface, and provides greatly enhanced features over the BDM you get with the D' family. This is still supported by P&E's BDM MultiLink12 cable, but I've also seen Nohau's BDM tool and ICE. The ICE is brilliant, and you should check it out for yourselves. Lastly, can I correct you on one point? The PWM features on the E-family are superior to those on the DP family. In addition to the 8x8-bit on the DP family, the E family has an additional 6 channels of 15-bit PWM, and also 12 (rather than 8) timer channels.

Hi Mark -- Could you give a brief synopsis of the E-family BDM improvements, relative to the D-family?
