Here s the result. After few seconds of displaying the Powered by FreeRTOS message, the demo will now display the status of all tasks. If there s no error occurred, it will show PASS and the jitter in the processing of timer interrupt (timertest.c). For the USART test (comtest.c), there s a loopback test of transmitted and received characters. Simply short the pins 2 and 3 (RX and TX) of CON1 in the Mini-STM32 board. Otherwise, it will show ERROR IN COM TEST message.
