[New CH554 Review] III. Formation Procedure [Copy link]

This post was last edited by ddllxxrr on 2018-4-6 17:16 According to the evaluation plan, this evaluation should be formed into a program. My idea is to merge the USB HID composite device program with the TOUCHKEY program. Of course, it is better to use the composite device as a template, and just copy TOUCHKEY.c and .h. Then add it to the project:

Add the touch button declaration in the main function

TK_Init( BIT4+BIT5+BIT6+BIT7, 1, 1 ); /* Choose TIN2, TIN3, TIN4, TIN5 for touchkey input. enable interrupt. */ TK_SelectChannel(0); /* NOTICE: ch is not compatible with the IO actually. */

复制代码

Then add the touch button judgment in the HID processing function:

void HIDValueHandle() { UINT8 i; // if(MISO == 0) // { // //printf( "%c", 1 ); // //HIDMouse[2] = 1; // //Enp2IntIn(); // i = 1; // } // else if(SCK == 0) // { // //HIDMouse[2] = -1; // //Enp2IntIn(); // i = 2; // // } // else // i = 'A'; if( Touch_IN != 0 ) { printf("come here 1...\n"); if( Touch_IN & CH2 ) { i = 'a'; } if( Touch_IN & CH3 ) { i = 'w'; } if( Touch_IN & CH4 ) { i = 'd'; } if( Touch_IN & CH5 ) { i = 's'; } Touch_IN = 0; } else i=0; switch(i) { //êó±êêyYé′êày case 1: //×óü HIDMouse[2] = -1; Enp2IntIn(); i=0; //HIDMouse[0] = 0; break; case 2: //óòü HIDMouse[2] = 1; Enp2IntIn(); i=0; //HIDMouse[0] = 0; break; //üìêyYé′êày case 'a'://Aü FLAG = 0; HIDKey[2] = 0x04; //°′ü aê Enp1IntIn(); HIDKey[2] = 0; //°′üáê while(FLAG == 0) { ; /*μè′yéò°ü′êíê3é*/ } Enp1IntIn(); i=0; break; case 'w': //Pü FLAG = 0; HIDKey[2] = 0x1a; Enp1IntIn(); HIDKey[2] = 0; //°′üáê while(FLAG == 0) { ; /*μè′yéò°ü′êíê3é*/ } Enp1IntIn(); i=0; break; case 's': //Pü FLAG = 0; HIDKey[2] = 0x16; Enp1IntIn(); HIDKey[2] = 0; //°′üáê while(FLAG == 0) { ; /*μè′yéò°ü′êíê3é*/ } Enp1IntIn(); i=0; break; case 'd': //Num Lockü FLAG = 0; HIDKey[2] = 0x07; Enp1IntIn(); HIDKey[2] = 0; //°′üáê while(FLAG == 0) {; èó|′eNAK UEP2_CTRL = UEP2_CTRL & ~ MASK_UEP_T_RES | UEP_T_RES_NAK; //èó|′eNAK break; } }

复制代码

Therefore, we add a judgment above, because the main function normally loops in the above function:

main() { CfgFsys( ); //CH559ê±ó mDelaymS(25); //DT÷μμè′yú2 §è¨,±ó mInitSTDIO( ); //′ ú03êˉ #ifdef DE_PRINTF printf("start ...\n"); #endif printf("start ddllxxrr ...\n"); USBDeviceInit(); //USBéè±￡ê3êˉ TK_Init( BIT4 +BIT5+BIT6+BIT7, 1, 1 ); /* Choose TIN2, TIN3, TIN4, TIN5 for touchkey input. enable interrupt.*/ TK_SelectChannel(0); /* NOTICE: ch is not compatible with the IO actually. */ printf("come here ...\n"); EA = 1; //êDíμ￥úD UEP1_T_LEN = 0; //¤ê1ó·￠í3¤èò¨òa UEP2_T_LEN = 0; //¤ê1ó·￠í3¤èò¨òa FLAG = 0; Ready = 0; //Port1Cfg(1,6); //Port1Cfg(1,7); while(1) { if(Ready) { while(1) { HIDValueHandle(); } } if( Ready&&(Ep2InKey == 0)){ #ifdef DE_PRINTF //áè DIDo printf("ID0 = %02x %02x \n",(UINT16)*(PUINT8C)(0x3FFA),(UINT16)*(PUINT8C)(0x3FFB)); printf("ID1 = %02x %02x \n",(UINT16)*(PUINT8C)(0x3FFC),(UINT16)*(PUINT8C)(0x3FFD)); printf("ID2 = %02x %02x \n",(UINT16)*(PUINT8C)(0x3FFE) ,(UINT16)*(PUINT8C)(0x3FFF)); #endif CH554USBDevWakeup(); // mDelaymS( 10 ); Enp1IntIn(); } mDelaymS( 100 ); //￡aμ￥ú×üê } }
