  • Using IR Sensor with C8051FX20-TR

    ———————————————————————-
    Hey everyone! I’m fairly new at using microcontrollers and right now I’m trying to get a infrared digital sensor (Sharp GP2Y0D810Z0F).
    I have connected the sensor to Port 7. I tried programming it using the code below (if the sensor detects something the green light on the microcontroller should blink):
    sbit front_ir = P7^0;
    sbit left_ir = P7^1;
    sbit right_ir = P7^2;
    sbit back_ir = P7^3;
    void main (void) {
    left_ir = 0;

    if(left_ir == 1){
    {
    // disable watchdog timer
    WDTCN = 0xde;
    WDTCN = 0xad;
    SFRPAGE = CONFIG_PAGE; // Switch to configuration page
    PORT_Init ();
    SFRPAGE = TMR3_PAGE; // Switch to Timer 3 page
    Timer3_Init (SYSCLK / 12 / 10); // Init Timer3 to generate interrupts
    // at a 10 Hz rate.
    EA = 1; // enable global interrupts
    SFRPAGE = LEGACY_PAGE; // Page to sit in for now
    while (1)
    { // spin forever
    }}}
    }
    However, it doesn’t seem to work. I feel like I’m missing something. I’d greatly appreciate any help!

    ---------------------------------------------------------------------- All I'm trying to do is send something to hyperterminal via UART1. My code for attempting this is below. Timer1_ISR just toggles P2 so I can verify my baud rate on a scope, which displays correctly at ~115200. Additionally, I have a board that connects P1.0 and P1.1 to UART1 which is why my XBR0 and XBR2 are set they way they are (via configuration wizard). Here is my concern. I keep coming across posts where people say that putchar is used to connect printf to UART1. But, do I have to use printf? Or, could my write to SBUF1 ...

    ---------------------------------------------------------------------- Hello, my only experience with uP's is with the 68HC12. Even then, it wasn't a lot. I seem to have a problem with timer 1. I'm trying to toggle P2 whenever Timer 1 overflow occurs. When looking at the P2.X on a scope, I am getting ~1.4MHz square wave. I'm using a 24.5MHz clock. I wrote my code with the understanding that when timer 1 overflows (mode 2, 8bit), the overflow flag would set, TH1 would reload TL1, overflow flag clears, and off it goes again. Therefore, with a 24.5MHz clock and an 8 bit timer, I figured I should ...

    ---------------------------------------------------------------------- I am using the C8051F120 and am having trouble getting UART1 to work. I got UART0 working very easily and assumed UART1 would not be much different. In my code (below), I have UART0 set for 19200 baud and UART1 for 115200 baud. UART0 works and UART1 does not, pretty simple. I've also noticed when I set both UARTS to 115200 baud, UART0 stops working. UART0 and UART1 do not need to receive data; just TX. I have another processor with code that uses UART1 and it works (i.e. I know it's not a HW issue). However, I don't have ...
    Hi, I'm trying to interface my C8051F120DK development kit to a Hitachi controller based HD44780 LCD screen. I'm using embedded C to program and here are some specs: P1 -ampgt; 3 pin control ports P2 -ampgt; 8 pin data ports Enables push-pull on P2. For some reason, my code keeps changing at LCD_Init, at the while loop towards the bottom where small_delay is called. I've browsed through 8051 forums for the last week and have found code similar to mine, but theirs work and mine doesn't. I've also tried to increase time delay in LCD_Init (doubled and tripled). My screen still displays nothing. I've pasted ...

    Hi guys, Recently, I've been trying to use the sample codes of C8051F120 DK: ADC and PCA (for PWM) in attempt to 1) produce a 100kHz, 28% duty cycle 3.3V PWM amp 2) read an analog voltage signal in the range of 0-2.43V and display it on Hyperterminal via UART1. Had realised that in order to create a 100kHz PWM, the CLK divider should be 0x20 and CLK multiplier should be about 0x21 to get that 100kHz, but if I change PLL0DIV = 0x20 and PLL0MUL = 0x21 accordingly, the display at the hyperterminal could not display the sensed mV ...

    Hi, I understand that by setting the correct PCA0H:PCA0L values into the respective registers could obtain the PWM frequency. PCA0H:PCA0L has 16 bits in total (hence 65536 clock pulses), and therefore by initialise the MSB to one's (eg: PCA0 = 0xFC00), we can obtain a n-bit PWM operation. However the problem I met is everytime the PCA0_ISR is being called, the content in the PCA0 registers reset to 0x0000, hence changing my PWM freq back to the default. I've tried to write PCA0H = 0xFC; into the PCA0_ISR subroutine but got a constant logic high at my output pin. Could anyone knows how do I ...
