Transmitting number as number through UART with STM32

i'm new to microcontrollers, i want to send numbers as numbers through UART using STM32 NUCLEOL053.

my script is:

uint8_t nums[8] = {0,1,2,3,4,5,6,7};

HAL_UART_Transmit(&huart2, nums, sizeof(nums), HAL_MAX_DELAY);

it does not work, how can i solve this? compiler tells me no error or warnings, i already know how to send numbers as string using sprintf but i need to send numbers as numbers

Solution

  • Try converting number in to ASCII and the call the function to transmit on UART.

    uint8_t nums[8] = {0,1,2,3,4,5,6,7};
char ascii_nums[8][5];

for(int i = 0; i < 8; i++) {
    itoa(nums[i], ascii_nums[i], 10); // convert the number to a string
}

    Note: You need to use for loop to transmit the numbers one after the other.
