Wangjialin	a6b3be6734	Update UART driver ... 1. fix bug in ringbuffer.c: When return an dummy item, free_ptr might exceed rd_ptr, so the write_ptr would overwrite rd_ptr in this case. 2. Delete UART tx task in buffer mode. UART ISR will copy the data from tx buffer to fifo.	2016-11-04 02:48:25 +08:00

Wangjialin	8d6b782327	Modify UART driver: ... 1. Add a ring buffer for UART TX. If the buffer size is set to zero, driver will not use a buffer. But we need a task to send data from buffer to fifo. I tried directly copy data in ISR, but the code looked too long for ISR. 2. Modify the format in uart.h	2016-11-01 09:22:09 +08:00
Wangjialin	74aff2b9d2	Update UART driver ... 1. Use esp_log API for LEDC and GPIO code. 2. Modify some API return value. 3. Add ledc_set_pin() for LEDC 4. Modify typo in uart.h Questions: In uart driver ISR handler, I used xxxFromISR , like xSemaphoreGiveFromISR, do those FromISR functions need to be put in IRAM?	2016-10-24 15:57:23 +08:00
