Teplotní alarm s přenosem teploty po UART

Já už nevím napadá mi jestli nedělám chybu TEMP_RESOLUTION protože nevím jak nastavit na 9 defaultně je 12.
Tento zdroják mi funguje

já jsem z něho vyrval jen tu část která by měla vyčíst teplotu s toho čidla, 
zakomentovaná proměnná ahoj to je zkouška převodu čísla na string a poslaní  na UART1   to funguje .
Ale teplota kterou si nastavím na čidle 69 stupňů v terminálu ukazuje 80 :blush:  :blush:
