A little error in Micro-Readerboard Technical Data webpage

[atommann]

In LED Micro-Readerboard, version 2.0: Technical Data, there are two errors in the font table at the end of the page.

First one:
P     80     abcdghpu     1100     0001     1001     1001     49561
Should be abcghpu ( no ‘d’)

Second:
R     82     abcghpru     1100     0101     1001     1001     30585

Should be 50585 instead of 30585

I checked the source code, it is correct in the code.

my quick and dirty to calculate the font table:

#include <stdio.h>
#include <stdint.h>

typedef enum segment {
//A, B, C, D, E, F, G, H, K, M, N, P, S, R, T, U,
// evil mad science
G, T, S, U, H, K, M, A, B, N, R, D, E, F, P, C,
} type_seg;

struct charset {
    char letters;
    char *lit;
} list[] = {
    {‘A’, “ghkru”},

    result = 0;

    while (out = list[j].lit[i++])

    }
    printf(“%c, %d”, list[j].letters, result);
