Customer #423228 on DEV-10593 - Gameduino

I bought this to get text to display on a monitor. I’m having two arduinos talk to each other through rf transmitters/receivers. I receive characters perfectly fine but I cannot get the characters I receive to display on the screen. I think it has to do with pointers and type conversions but I am not sure. Does anyone have any recommendations? My code to display in void loop() is:

uint8_t buf[VW_MAX_MESSAGE_LEN]; uint8_t buflen = VW_MAX_MESSAGE_LEN;

if (vw_get_message(buf, &buflen)) // Non-blocking {

 int i;
 int z=1;
 digitalWrite(led_pin, HIGH); // Flash a light to show received good message
 // Message with a good checksum received, print it.
 for (i = 0; i < buflen; i++)
 {
    char myChar = buf[i];
drawstr(atxy(i,z), myChar);
 }
 z++;
 digitalWrite(led_pin, LOW);

}

and the method drawstr is: static void drawstr(uint16_t addr, const char s) { while (s) {

uint16_t w = pgm_read_word(cp437_pic + 2 * *s);
GD.wr(addr, lowByte(w));
GD.wr(addr + 64, highByte(w));
s++, addr++;

} }

and a drawstr input that works is: drawstr(atxy(1, 1), “0)”);

Thanks in advance for any help!
