| What is the slave doing to respond to a read from the master?
At 100kHz, nothing. It acts like "never see the address". No SCL hold and no interrupt. This PIC (16F87) uses "SSP&qu ... |

| The pullup resistor is 4.7k ohms. The Vcc (bus voltage) is 5 volts.
It goes through a short (2 inches) ribbon cable. There is no bus capacitance and serial resistor. I can control the I2C master ... |

| I have a PIC16F87. It uses the internal 8MHz clock and runs as an I2C slave.
It works fine if the master I2C device runs at 60kHz. However, if the master I2C device runs at 100kHz and sends a re ... |
