I have assigned the string into the char array as "example\n". How do I put the "\n" character in front of the "example\n". I wanted like this "\nexample\n" on the char array

Is this possible to do?

HAL_UART_Receive_DMA and haldull is inside the while(1) loop. I am trying to read some string (TEMP + arguments) from the huart2 and then sending that data to huart1. huart1 is connected to API to display that data on screen. My intention is to stop ...

Yes, I forget to mention I have second switch to turn off the same LED. void EXTI15_10_IRQHandler(void) { HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_10); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_11); } void HAL_GPIO_EXTI_IRQHandle...

Thank you for the replies. Is it possible to buffer 2KB of data to store into memory as a serial protocol over the USB. I couldnt find any examples how to do that. Any help on this.

I have a problem with HAL_UART_Transmit() function. I have a endless loop until switch press to stop it HAL_UART_Transmit data. But after 3500 cycles HAL_UART_Transmit() stops transmitting. Any idea about this

I have a problem with EXTI. I have connected switch with EXTI pin. When the switch is pressed first time it light up the led. But when I pressed the same switch second time it does not light up the led.

I have a button connected to STM32F405. I am using external interrupt with the button. Inside the callback of the external interrupt I am sending a command to retrieve some data from another microcontroller as a loop. But I am receving only data once.

I have a two dimensional array char as str[2][10].

I wanted to store some data on the flash memory of the STM32F405RGT6. I wanted to do with windows application to send that data to the flash memory of the STM32F405RGT6. I am building up custom windows application to connect with STM32F405RGT6.
