Ring buffer functions on LPC51U68

[carlosmedeiros]

Hello,

I'm worlking with LPC51U68 and I would like to know if there are ring_buffer scripts to use with USART. I already seen that for LPC11Uxx there is a ring_buffer.c and that the uart_11xx.c also has functions as Chip_UART_SendRB() and Chip_UART_ReadRB() the manipulate this buffers.

Is there any of this functions available for LPC51U68 , or do I have to created myself based on the general ring_buffer.c script and USART functions?

Thank you,

Carlos Medeiros

HI Carlos,

ring_buffer.c  commonly exists in LPCOpen package. LPC51U68 is NXP new launched product (Lunch date: Jun 2018) which is supported by MCUXpresso SDK only. LPCOpen only support legacy product. There is no plan to support LPC51U68 in LPCOpen.

I suggest you refer MCUXpresso SDK demo code:

Welcome | MCUXpresso SDK Builder 

There is interrupt_rb_transfer demo project included inside. it shows how to use uart driver in interrupt way with RX ring buffer enabled.

Have a great day,
Jun Zhang
