Posted on June 15, 2012 at 18:08Hello guys, I've got the following problem: I'm trying to read a register of a gyroscope with IÂ²C. Everything works fine as long as I'm using several delays during the IÂ²C communication. This wasn't a problem until ...

Posted on July 08, 2012 at 10:15Awesome! I managed to solve it now! The problem indeed was the AcknowledgeConfig. Seems like one of the devices doesn't acknowledge the writte read address operation. Correct code now is: uint8_t I2C_Read_Byte(uint8_t...

Posted on June 19, 2012 at 14:32Right then I'm going to check the I²C communication with a scope. I thought I2C_AcknowledgeConfig(I2C1, DISABLE); disables ack? What happens if I disable acknowledgement and the slave sends an ack? When I first tried ...

Posted on June 19, 2012 at 12:57That's a relly good idea, thanks!  None of the 2 devices I'm using needs a delay in the I²C communication. Both sensors need time to sample new values, but the registers may be read at any time. Actually I start to b...
