Detailed Description

This file contains macros, prototypes, and definitions for STM32L4xxx Family specific communications on ESOS32.

This file contains routines which configure and use the UARTs on the ST32L4. We rely on the HAL to do lots of the heavy lifting here. Probably should move to the HAL_LL_xxx functions to improve performance.

Macro Definition Documentation

IS_CHAR_READY_UART1

#define IS_CHAR_READY_UART1

(

)

ESOS is built with a single communications channel using UART at 57.6kbaud 8/N/1

Only uncomment the line below if you want ESOS to build the UART with a "non-standard" baudrate. Used by configUART1 to set up the UART.

 #define DEFAULT_BAUDRATE  9600

Determine if a character is available in the UART's receive buffer.

Returns

True (1) if character is available, 0 if not.

Definition at line 83 of file esos_stm32l4_rs232.h.

IS_TRANSMIT_BUFFER_FULL_UART1

#define IS_TRANSMIT_BUFFER_FULL_UART1

(

)

Determine if a the transmit buffer is full.

Returns

True (1) if the transmit buffer if full, false (0) if not.

Definition at line 89 of file esos_stm32l4_rs232.h.

IS_TRANSMIT_COMPLETE_UART1

#define IS_TRANSMIT_COMPLETE_UART1

(

)

Determines if all characters placed in the UART have been sent. Returns 1 if the last transmission has completed, or 0 if a transmission is in progress or queued in the transmit buffer.

Returns

True (1) if the last transmission has completed, 0 if not.
