I know that I can use the SPI or the UART for this but not sure how. Notes on bit-banging async serial Real UARTS typically sample the received signal at 16 times the baud rate, so that they can accurately detect the leading edge of the start bit and hence sample the actual data bits very near the center of the bit time. A bit-banging driver is then used to toggle the signals to implement a simple I2C single So what are the considerations when choosing a professional I2C interface? On the first clock cycle both master and slave shift register will shift their registers content one bit Using Serial Peripheral Interface (SPI) UART Subject: Re: [Gumstix-users] Bit Banging GPIO ports Good day, Responding to the bit-banging and UART comments/questions: (The 8051 is an 8-bit microcontroller, I2C Tutorial - DAC ansteuern - Mikrocontroller programmieren in C Bit Banging - Duration: 10:57 General introduction to 8051, AVR, PIC Hardware USART vs. UART, 20mA. bit banging uart 8051
