Web8 Jan 2024 · Sets the I2C clock divider by converting the baudrate parameter to the equivalent I2C clock divider. ( see See also bcm2835_i2c_setClockDivider) For the I2C standard 100khz you would set baudrate to 100000 The use of baudrate corresponds to its use in the I2C kernel device driver. (Of course, bcm2835 has nothing to do with the kernel … Web5 May 2024 · SPI.setClockDivider (SPI_CLOCK_DIV2); How can I use the max. clock speed of 8 MHz -no devider or something else. The Default-value is 2 MHz. Not possible.Since you micro is running at 8Mhz the max rate the SPI interface can work is Fosc/2 so you can configure it at a maximum speed 4Mhz clock.
