WebJun 8, 2024 · Modifying the FreeRTOS Binary Semaphore schematic and adding the UART ISR. Add a FreeRTOS Binary Semaphore called “uartSemaphore” that I will set in the UART ISR. Turn on interrupt handling for the UART when there is one or more characters in the buffer. In the ISR turn off interrupts and set the “uartSemaphore”. WebFurthermore, both categories have the same operations: wait and signal. The main difference between binary and counting semaphores is the number of access units made …
