Data Structures | |
struct | lpc_enetdata |
Debug output formatter lock define When using FreeRTOS and with LWIP_DEBUG enabled, enabling this define will allow RX debug messages to not interleave with the TX messages (so they are actually readable). Not enabling this define when the system is under load will cause the output to be unreadable. There is a small tradeoff in performance for this so use it only for debug. More... | |
Functions | |
void | msDelay (uint32_t ms) |
MilliSecond delay function based on FreeRTOS. | |
#define | tskTXCLEAN_PRIORITY (TCPIP_THREAD_PRIO - 1) |
Driver transmit and receive thread priorities Thread priorities for receive thread and TX cleanup thread. Alter to prioritize receive or transmit bandwidth. In a heavily loaded system or with LWIP_DEBUG enabled, the priorities might be better the same. | |
