Given the following function
UART_write(UART_Handle handle, const void *buffer, size_t size);
I want to send via uart a int8_t value ( log it )
What i tried:
int8_t value;
UART_write(uart, value, strlen(value));
const char *echoPrompt = (char *)value;
UART_write(uart, echoPrompt, sizeof(echoPrompt));
const char echoPrompt2[] = {value};
UART_write(uart, echoPrompt2, sizeof(echoPrompt2));
const char* buff = value;
UART_write(uart, value, strlen(value));
The best i got is logging the hex value
Exemple of how the uart_write function works: In orded to log "12" what I need to do is
const uint8_t value[] = {0x31, 0x32};
UART_write(uart, value, sizeof(value));
So my question is, how to log my int8_t variable ( I need to log negative numbers as well)
