[3DP] MKS TFT32 만들기

2024.06.10

TFT35 (TS35?) 를 LCD + Arduino로 만드는 것을 다시 생각.

copilot에게 interface 물어 봤더니 링크를 알려준다.

GitHub - makerbase-mks/MKS-TFT: MKS TFT touch screen includes TFT24/28/32/35/70, which can be connected to the motherboard for control via AUX-1. Support Simplified Chinese, Traditional Chinese, English, Russian, Spanish and more than 5 languages, and support online language switching ...

Firmware가 있다.

STM32 기반이다.

집에 있는 ESP32로 가능할 것 같기도 한데.

일단 펌웨어 분석

 

#3은 HW UART?

    gCfgItems.baud = 4;

    MX_USART3_UART_Init(gCfgItems.baud);

void MX_USART3_UART_Init(int readId)

{

  huart3.Instance = USART3;

  if(readId==1){

    huart3.Init.BaudRate = 9600;

  }

  else if(readId==2){

    huart3.Init.BaudRate = 57600;

  }

  else if(readId==3){

    huart3.Init.BaudRate = 115200;

  }

  else{

    huart3.Init.BaudRate = 250000;

  }

#1은 WiFi 같음

   MX_USART1_UART_Init(5);

void MX_USART1_UART_Init(int readId_1)

{

  huart1.Instance = USART1;

  switch(readId_1)

  {

    case 1:huart1.Init.BaudRate = 9600;break;

    case 2:huart1.Init.BaudRate = 57600;break;

    case 3:huart1.Init.BaudRate = 115200;break;

    case 4:huart1.Init.BaudRate = 250000;break;

    case 5:huart1.Init.BaudRate = 1958400;break;

    default:huart1.Init.BaudRate = 115200;break;      

  }

 

#2는 SW UART?

mksUsart2Init();

void mksUsart2Init(void)

{

        firmwareType = marlin;

        wait_cnt = 0;

        usart2Data.rxP = &usart2Data.usart2Rxbuf[0];

        usart2Data.txP = &usart2Data.usart2Txbuf[0];

        usart2Data.txBase = usart2Data.txP;

        usart2Data.printer = printer_idle;

        usart2Data.timer = timer_stop;

        usart2Data.prWaitStatus = pr_wait_idle;

        USART2_SR &= 0xffbf;        //����жϱ�־λ

        USART2_SR &= 0xffdf;

        USART2_CR1 |= 0x40;         //��������ж�����

        USART2_SR &= 0xffbf;        //����жϱ�־λ

 

M81(Power Off)를 UART2에 전송하는 것으로 보아 Marlin과 통신은 #2로

void Btn_putdown_close_machine()

{

    //**initFIFO(&gcodeCmdTxFIFO);

    //**pushFIFO(&gcodeCmdTxFIFO, (unsigned char *)"M81\n");

    memset(usart2Data.usart2Txbuf,0,sizeof(usart2Data.usart2Txbuf));

    usart2Data.usart2Txbuf[0]='M';usart2Data.usart2Txbuf[1]='8';usart2Data.usart2Txbuf[2]='1';usart2Data.usart2Txbuf[3]='\n';  

    usart2TxStart();        

}

지난번 확인한 대로 Marlin <- UART -> TFT35로 연결되어 GCode를 UART로 통신
