WebOn 8051, the output is performed by the simple SBUF = c; where SBUF is the 8051's serial port register. You write to SBUF to send something, and you read from SBUF to grab what was transmitted. Other processors have different hardware for dealing with a UART, so you would "retarget" the low-level code for each. WebMay 15, 2024 · (After one consumer_1 finish sbuf_remove, items become 0 but consumer_2 already pass P(&sp->items) code. Therefore consumer_2 fail to get correct item and return unexpectable value.) I am wondering why package developer did not use mutex's lock … craft plastic
