Hi,
I am still using the LPC2138 ;). Now I have a problem with I2C. When I try to send some bytes to an EEPROM device, the following happens:
- I2C start condition is made
- interrupt is generated
- I2C address is sent
- EEPROM device gives an ACK
And now nothing happens. If I look at the I2C bus state, the microcontroller accepted the ACK. However, no new interrupt is given due to a bus state change. The SI bit is high in the control register.
Should I continuously receive interrupts when the SI bit is set? If so, maybe at a higher level the interrupt is turned off. Any other ideas?
TIA, Frank
