I'm making a research for a project starting next month and i'm looking for some opinions before making decisions, since we've never used freescales before
my particular assigment involves
real time clock
buttons, maybe 4
some LEDs and miscelaneous ON/OFF
low voltage detect
80 pins are ok, 144 is a bit of an overkill but i wont complain.
if i get PWM, input capture / output compare / counter / event counter, freaking great.
this is how i ran into the S12K, has
2 SCI to place my 232 and modbus
3 SPI, 1 to hang a micro SD card socket and the real time clock, 1 to communicate with other devices, 1 bonus
- dont know yet what to do with the LCD -
bonus PWM, timer module and IIC
and meets all other requirements
so, how much of a bad idea is this arrengement? advices, ayone? does anyone knows of a more suitable micro to do the magic? i've seen micros with LCD drivers and/or external memory drivers, but i'm reaaaaally interested on the character LCD and the micro SD card. What can i do with the LCD?
someone suggested the K60 but, adding such "complex" graphics antics to our proyect will just rise the price out of competition worthlessly: people shouldn't be around our product under normal circumnstances anyways, just for emergency or maintenance.
USB and Ethernet were considered, but they are more of a fun plus than an actual need
well, i'm open for suggestions. thanks in advance.
