    generate two PWM signal with only 2 CCR ( CCR0 & CCR1)

    I also have the same question about PWM output in MSP430. I have a MSP430F169, and i need output nine channels of PWM wave. Can I do it ? Now I can have eight channels not nine channels. First, in TIMER A, TACCR0 for period, TACCR1 for one duty cycle, and TACCR2 for another duty cycle. Second...

    subtract in assembly code in pic16f628a

    assembly subtract subtract in assembly code in pic16f628a I need subtract for three times in assembly code in pic16f628a. I wrote a stupid code, it is too long. and I am wondering whether I can use a loop to do it. 1) the data is saved in 0x40~0x51.The data is from 8channels, every channel is...

    transmit data to usart port of pic16f877 in assem code

    usart pic16f Hi everyone. How is your everything? I need your help to modify assembly code of transmitting data to usart port of pic16f877. Before I transmit 2 byte data into TXREG, need I check TXIF value? The first time, TXIF itself is empty. but the second time, CHECK TXIF is necessary...

    USART ASYNCHRONOUS RECEPTION IN PIC16F877A

    C7 is usart reception pin. You need define C7 direction in code. Such as " banksel TRISC bsf TRISC,7 ;c7=0 as input" good luck.

    xbee data lost- Why is the rx data different from tx data?

    xbee data lost Hi everyone. My question is. when I send a bitstream at 19.2k in tx xbee chip802.15.4 the data is 000000FFFFFF000000FFFFFF000000......(repeat) but from rx xbee , I received the data is 0000FFFF0000FFFF......(repeat) XBEE Baud rate is 19.2k so what's the reason? Why is the rx...
