Do I need to convert ascii to uint8_t to write and display over uart (putty)
<p>I've a sensor connected on UART to an mcu. The sensor outputs ascii characters. Below are my functions to read from the uart (the sensor) and write from the uart (to my computer over putty). </p>

<p>My question is, do I need to convert the ascii characters to be of type <code>uint8_t</code> to write over the uart as that is what putchar() requires? There is noting being displayed in putty. </p>
