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 ( )

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 88 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 94 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.

Definition at line 101 of file esos_stm32l4_rs232.h.

◆ USART_CONSOLE

#define USART_CONSOLE USART2

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
