My new toy!

Took me two weeks just to get the demo code to work dahil di ko alam kung paano ko sisimulan. Parang Hitech-C ang paggamit ng Keil MDK, halos walang built-in routines sa IDE, puros include files lang. Halos walang mga tutorials sa net except for those stm32 primers and expensive cortex-m3 development boards so you have to modify or based your wiring dun sa mga existing tutorials or sample codes.

San dumami pa ang mga arm cortex-m3 users particularly itong stm32. We dont actually need a programmer because it already includes a built-in bootloader from factory. So via serial port na lang ang loading ng hex file. Yung jtag is only used for debugging.

wala nga silang mga built in commands, nakaasa lahat sa libraries na given nung manufacturer. ginagamit ko 'yung library ng ST.

madalas ginagamit ko lang 'yung given na startup assembly file tapos 'yung libaries. sa tutorial hindi pa ako umaabot sa retargetting (linagpasan ko muna dahil mukhang di ko pa naman gagamitin. hehehe). pero November pa ako last nag-program. hehehe. 'yung libraries ng ST, medyo malaki at maraming references to other libraries kaya medyo matagal kung gusto talaga pag-aralan kung bakit ganun 'yung codes sa library.

konti pa ang nakikita kong gumagamit ng Cortex M3 sa hobbyists compare sa ARM7.

^ maganda talaga ang ARM9. Saan po may pinakamurang mabibilhan ng boards na yan?

Nag search din ako nyan and my pick would be this:

The ET-STM32 Stamp board so far is the cheapest and hobbyist friendly board I could find. USD25 + USD7 shipping from futurlec.com

It uses a STM32F103RET6 512KB flash + 64KB RAM.

Maybe we should make "PIKIT" type project for this. 32-bit MCUs are the future.

^Kakainggit

but thats way out of my league $:-\$ . Dami din nagkalat sa ebay na mga arm9 dev board na may touch screen using a samsung 500Mhz mcu. Yung mga sample os s/w eh embedded windows ce or embedded linux ..... more of 95 percent pda eh pda na talaga.

Very good idea sir since you have already started with the pikit2.
