Pin Configuration and Summary Data Sheet J3 Pin Outs (User Interface): Pin Symbol I/O Description 1 Vin P Main Voltage Supply +ve input pin. Reverse polarity protected. Range is 4.0V to 5.5V, nominal 5.0V. Asynchronous Serial Transmit pin. Connect this pin to host micro-controller 2 TX O Serial Receive (Rx) signal. The host receives data from the display module via this pin. This pin is tolerant up to 5.0V levels. Asynchronous Serial Receive pin. Connect this pin to host micro-controller Serial 3 RX I Transmit (Tx) signal. The host transmits commands and data to the display module via this pin. This pin is tolerant up to 5.0V levels. 4 GND P Supply Ground. Master Reset signal. Internally pulled up to 3.3V via a 4.7K resistor. An active Low pulse greater than 2 micro-seconds will reset the module. If the module 5 RES I needs to be reset externally, only use open collector type circuits. This pin is not driven low by any internal conditions. The host should control this pin via one of its port pins using an open collector/drain arrangement. © 2010 4D Systems www.DataSheet.in www.4dsystems.com.au Page 5 of 24 5 Page µLCD-32PT(GFX) Data Sheet • media_SetAdd(HIword, LOword) • media_SetSector(HIword, LOword) • media_RdSector(Destination_Address) • media_WrSector(Source_Address) • media_ReadByte() • media_ReadWord() • media_WriteByte(byte_val) • media_WriteWord(word_val) • media_Flush() • media_Image(x, y) • media_Video(x, y) • media_VideoFrame(x, y, frameNumber) Flash Memory chip Functions: • flash_SIG() • flash_ID() • flash_BulkErase() • flash_BlockErase(blockAddress) SPI Control Functions: • spi_Init(speed,input_mode,output_mode) • spi_Read() • spi_Write(byte) • spi_Disable() Serial (UART) Communications Functions: • setbaud(rate) • com_SetBaud(comport, baudrate/10) • serin() or serin1() • serout(char) or serout1(char) • com_Init(buffer, buffsize, qualifier) or com1_Init(buffer, buffsize, qualifier) • com_Reset() or com1_Reset() • com_Count() or com1_Count() • com_Full() or com1_Full() • com_Error() or com1_Error() • com_Sync() or com1_Sync() • com_TXbuffer(buf, bufsize) or com1_TXbuffer(buf, bufsize) • com_TXcount() or com1_TXcount() • com_TXemptyEvent(function) or com1_TXemptyEvent(function) I2C BUS Master Function • func I2C_Open(Speed) • func I2C_Close() • func I2C_Start() • func I2C_Stop() • func I2C_Restart() • func I2C_Read() • func I2C_Write(byte) • func I2C_Ack() • func I2C_Nack() • func I2C_AckStatus() • func I2C_AckPoll(control) • func I2C_Idle() • func I2C_Gets(buffer, size) • func I2C_Getn(buffer, size) • func I2C_Puts(buffer) • func I2C_Putn(buffer,count) Timer Functions: • sys_T() • sys_T_HI() • sys_SetTimer(timernum, value) • sys_GetTimer(timernum) • sys_SetTimerEvent("timernum","functin") • sys_EventQueue() • sys_EventsPostpone() • sys_EventsResume() • sys_Sleep(units) • iterator(offset) FAT16 File Functions: • file_Error() • file_Count(filename) • file_Dir(filename) • file_FindFirst(fname) • file_FindNext() • file_Exists(fname) • file_Open(fname, mode) • file_Close(handle) • file_Read(destination, size, handle) • file_Seek(handle, HiWord, LoWord) • file_Index(handle,Hisize,Losize,recrdnum) • file_Tell(handle, &HiWord, &LoWord) • file_Write(Source, size, handle) • file_Size(handle, &HiWord, &LoWord) • file_Image(x, y, handle) • file_ScreenCapture(x, y, width, height, handle) • file_PutC(char, handle) • file_GetC(handle) • file_PutW(word, handle) • file_GetW(handle) © 2010 4D Systems www.DataSheet.in www.4dsystems.com.au Page 11 of 24 11 Page
