Ich habe grade mal versucht anhand des Datenblatts ein kleines Programm in Bascom zu schreiben, um das Display anzusteuern.
Ich habe leider grad das Display nicht zur Hand, aber würde das nach diesem Muster in der Theorie funktionieren?

Code:
$regfile "m8def.dat"
$crystal = 1000000

Config Portd = Output
Config Portb = Output




'Init

E = 1
E = 0
Rw = 0
Rs = 1
Portd = 0
Rw = 0
Rs = 0
Portd = 0b00100100

Rw = 0
Rs = 1
Portd = 0x01

Rw = 0
Rs = 0
Portd = 0b10010110

Rw = 0
Rs = 1
Portd = 0x02

Rw = 0
Rs = 0
Portd = 0x16

'(Rw = 0
Rs = 1
Portd = 0x03
')

'(Rw = 0
Rs = 1
Portd = 0x04
')


'Test ausgeben

Rw = 0
Rs = 1
Portd = 0x0c

Rw = 0
Rs = 0
Portd = 0b01010100                                          'T

Rw = 0
Rs = 1
Portd = 0x0c

Rw = 0
Rs = 0
Portd = 0b01100101                                          'e

Rw = 0
Rs = 1
Portd = 0x0c

Rw = 0
Rs = 0
Portd = 0b01110011                                          's

Rw = 0
Rs = 1
Portd = 0x0c

Rw = 0
Rs = 0
Portd = 0b01110100                                          't
