STM32F103Cx MCU major(timer, UART, EXTI) function entry names
-STM32F103Cx MCU 주요 함수 시작점 및 KEYPAD용 GPIO port
<pre>
1. timer - automatic generated function called in every 1 milisec
SysTick_Handler() //stm32f1xx_it.c,
|
+-> HAL_IncTick();
+-> HAL_SYSTICK_IRQHandler()
|
+-> HAL_SYSTICK_Callback() ; //main.c weak void HAL_SYSTICK_Callback()
2. UART RECV callback - Rx Transfer completed callbacks.
// * @param huart Pointer to a UART_HandleTypeDef structure that contains
// * the configuration information for the specified UART module.
__weak void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) //stm32f1xx_hal_uart.c
--> void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) //main.c
3. EXTI(external interrupt) callback
EXTI0_IRQHandler()//stm32f4xx_it.c
|
+->HAL_GPIO_EXTI_IRQHandler() //stm32f1xx_hal_gpio.c
+-> HAL_GPIO_EXTI_Callback() // main.c
4. Timer callback - custom timer period timer
HAL_TIM_IRQHandler(TIM_HandleTypeDef *htim)//stm32f1xx_hal_tim.c
|
+-> HAL_TIM_PeriodElapsedCallback() // main.c
A. KEYPAD CFG
const KEYPAD_CfgType KEYPAD_CfgParam[KEYPAD_UNITS] =
{
// KeyPAD Unit 1 Configurations
{
/* ROWs Pins Info */
{GPIOB, GPIOB, GPIOB, GPIOB},
{GPIO_PIN_4, GPIO_PIN_5, GPIO_PIN_6, GPIO_PIN_7}, // input pin
/* COLs Pins */

Send and Receive data to PC without UART (STM32 USB COM)
This tutorial will show you how can we use the STM32 USB to send and receive data from the computer, just like we did using the UART

CubeIDE , Keil have different requirement for Serial Wire Viewer
- CubeIDE :
> _write() redefinition is required
//in CubeIDE, redefinition of _write is ncessary
int _write(int file, char *ptr, int len)
{
for(int i = 0; i < len; i++)
{
ITM_SendChar(*ptr++);
}
return len;
}
Using Serial Wire Trace with CubeIDE (aka a new level of debugging) – EmbedBlog
I’ve been developing for STM32’s for a couple of years now, and I did a lot of different projects – from large powersupplies to small headlamps – but on 95 % of them, I used two connectors: SWD (Serial Wire Debug), used to program and debug the chi

Posted on June 11, 2015 at 13:14 Hi i am new to embedded system programming and stumbled upon this basic problem of re-directing output to the ITM Port0. I read multiple posts on the same but sadly I cant get it to work. I shall try to be as descriptive as

How to use flash memory as a EEPROM in STM32G071CBT6
Hello! I'm using the STM32G071CBT6 controller for my project. I need to store certain values in EEPROM for my project, but unfortunately, this controller doesn't have built-in EEPROM functionality. Despite this limitation, I'm determined to find a solution
