I need to transmit my getting data from adc. But as I am very bigger I do not know how to do it, I would be happy if you take a look at my code in attachment and give me idea. Thanks

Yes, syntax is wrong for HAL_UART_Transmit(), it wants a POINTER, and will send a pair of raw bytes over the wire. Will look like random junk bytes in a terminal application.

HAL_UART_Transmit(&huart1, (uint8_t *)&readValue, sizeof(readValue), 100);

for human readable numbers

char string[10];

HAL_UART_Transmit(&huart1, (uint8_t *)string, sprintf(string, "%d\n", readValue), 100);

Post code in-line via </> icon, screen shots are unhelpful

Thanks for the reply :folded_hands:

but again the problem is not solved!

>>but again the problem is not solved!

"The Problem" is ill defined.

No idea what board or chip you are using.

No idea how and to what the UART is configured and connected.

No idea what terminal app you have connected, what you are seeing, or what you expect to see.
