STM32 character sending function notes-EEWORLD

Collect

1. Sending function

void UART2_Put_Char(u8 data)

{

USART_SendData(USART2, (uint16_t) data);

while(USART_GetFlagStatus(USART2, USART_FLAG_TC)!= SET)

delay_10us(1);

}

II. Description

1. The while loop function in the above code is to check whether the sending is completed. If not, it will delay;

2. That is to say, when sending a string, you must pay attention to whether the first character is sent when sending the second character. I didn't have this awareness before. Although there has been no problem, I will pay attention to it in the future.

How to see the program occupying STM32 flash and SRAM from the Keil compilation result

Program Size: Code=114956 RO-data=20528 RW-data=808 ZI-data=702360 FromELF: creating hex file... "..\OBJ\MALLOC.axf" - 0 Error(s), 0 Warning(s). Build Time Elapsed: 00:00:05 From the compilation information above, we can see that the FLASH size occupied by our code is: 135484 bytes (114956 +20528), and the SRAM s

STM32: Flash erase and read and write operations

Application platform: STM32F030F4P6 ST official library: STM32Cube_FW_F0_V1.9.0 background knowledge For most MCUs and microcontrollers (ARM, x86), the address space is in bytes, which means that one address is one byte. Flash memory has a characteristic that it can only write 0, not 1. So if there is data at the

STM32 multiplexing and remapping (USART Remap)

Hello everyone, starting from today, I will share and discuss the problems I encountered in my work and my learning experience with you. Let me tell you about the port remapping of the STM32 microcontroller, because I use myself as an example. Here is the remapping of USART1 as an example. Because I want a TF

Create a C++ STM32 development project on MDK

Recently, I was surprised to find that C++ can be used for embedded program development, even bare system program development. Before, when developing microcontrollers and programs on STM32, I only thought of C language and assembly language, and never considered that C++ language could be used for development.

stm32-GPIO operation (library function)

It's rare to have time, so I want to write about the basics of stm32 recently. 8 ways of GPIO 1. Floating input GPIO_IN_FLOATING ——Floating input, can be used for KEY recognition, RX1 2. GPIO_IPU with pull-up input——IO internal pull-up resistor input 3. GPIO_IPD with pull-down input——IO internal pul

STM32 learning notes: use of external interrupts

The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counter interrupts and one serial port interrupt. However, in STM32, the number of interrupts has greatly increased, and the i

STM32 motor control synchronous electrical angle test description

Preface When using the ST FOC motor library , when using the Hall signal as the position signal, it is necessary to input the synchronous electrical angle data. This data is input according to the characteristics of the current motor in use, and the electrical angle will be synchronized every time the Hall signal ch
