xQueueSendFromISR

xQueueHDLC = xQueueCreate( 100, sizeof( u8 ) ); … in IRQ : xTaskWokenByPost = pdFALSE; for(addr = recv_buf_addr; addr<(recv_buf_addr + 150);(addr+=1)) {   cIn = (*(u8 *)addr);   xTaskWokenByPost = xQueueSendFromISR( xQueueHDLC, &cIn, xTaskWokenByPost ); } if we create a queue with 100 bytes and we send more than 100 bytes in the queue, how FreeRTOS is managing this? Or we must manage it with a counter? Thanks. Chris.

The character will be lost!  If there is no room on the queue the ISR cannot block so the character has nowhere to go.
