    switching to arm microcontroller

    yeah,you can learn the STM32 for your ARM switch,because it have more source such learning example,develoment board and soon。 but you can also select the NXP,it's similar with the ST.

    [ARM] STM32, FatFS and NandFlash ?

    which chip do you use ? i have some example with STM32f407,it have fatfs and nandflash ,but if you often write and read,it wile have a little bug.so you must buy a good system.

    How to write a CCS code for ultrasonic sensor HC-SR04

    I'm from in china, I focus on the parking lot,so i use the ultrasonic sensor.First you must transfer eight the square wave,then the HR04 will transfer a square wave for indicate the distance.so after you transfer eight square wave and "while(!input(ECHO))" ,you must clear the timer value and...
