use rtx traffic example of stm32f103. I get rid of parts of lcd, only keep uart. when I press space button , the terminal show many wrong characters. when I press ESC continuously..(keep press...) after 30 ~ 60 seconds, the system crash....
keil 4.12 arm. rl-arm 4.12 exmple: rtx traffic (serial use event driver)
Note: don't select the "microlib".
the detial is:
1. the example of rtx traffic under \boards\keil\stm32.. 2. get rid of lcd part because i havn't lcd.
that's all. no other modification!!
then downlaod the hex to stm32f board. no matter stm32f103rb or stm32f103vc....
then you connect the uart1 and PC use a cable, you will find these bugs when you pressing "space" button or you always pressing the ESC button until the system crash.
