Description

Le WEO012832N est un affichage OLED graphique COG de 2,23 pouces, composé d'une résolution de 128x32 pixels. Ce module est équipé du circuit intégré SH1106 ; il peut être communiqué via des interfaces parallèles 6800 ou 8080, SPI à 4 lignes et I2C ; la tension d'alimentation pour l'affichage est de 12V (valeur typique), avec un cycle de fonctionnement de 1/32, la tension d'alimentation logique est de 3,0V (valeur typique), et le courant avec un affichage en damier à 50% est de 15mA @ 12V VCC (pour la couleur blanche). Le modèle WEO012832N est une solution alternative à circuit intégré du modèle WEO012832A ; les caractéristiques électriques et la définition des broches FPC sont identiques. Les clients doivent ajuster uniquement le code initial. Le module WEO012832N prend en charge l'alimentation interne par pompe de charge et l'alimentation externe VCC.

Le modèle WEO012832N est idéal pour les applications domotiques intelligentes, les m-POS, les systèmes IoT, les appareils technologiques intelligents, les systèmes énergétiques, les systèmes de communication, les instruments médicaux, la recharge des véhicules électriques, etc. Ce module peut fonctionner à des températures allant de -40℃ à +80℃ ; ses températures de stockage vont de -40℃ à +85℃.

IM1 1 1 0 0
IM2 1 0 1 0
These are the MPU interface mode select pads.
7 IM2
8 ___
CS
This pad is the chip select input. When CSB = “L”, then the chip select becomes active, and data/command I/O is enabled.
9 ___
RES
This is a reset signal input pad. When RES is set to “L”, the settings are initialized. The reset operation is performed by the RES signal level.
10 A0 This is the Data/Command control pad that determines whether the data bits are data or a command.
A0 = “H”: the inputs at D0 to D7 are treated as display data.
A0 = “L”: the inputs at D0 to D7 are transferred to the command registers.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver.
11 ___
WR
This is a MPU interface input pad.
When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU WR signal. The signals on the data bus are latched at the rising edge of the WR signal.
When connected to a 6800 Series MPU: This is the read/write control signal input terminal.
When R/W = “H”: Read.
When R/W = “L”: Write.
12    ___
E/RD
This is a MPU interface input pad.
When connected to an 8080 series MPU, it is active LOW. This pad is connected to the RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”.
When connected to a 6800 series MPU , this is active HIGH. This is used as an enable clock input of the 6800 series MPU.
When RD = “H”: Enable.
When RD = “L”: Disable.
13~20 D0~D7 This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). At this time, D2 to D7 are set to high impedance.
When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance.
21 IREF This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75uA.
22 VCOMH This is a pad for the voltage output high level for common signals.
A capacitor should be connected between this pad and VSS.
23 VPP OLED panel power supply. Generated by internal charge pump.
Connect to capacitor. It could be supplied externally.
24 NC(GND) No connection.
