have you tested 4 I2C channels @ 100 kbit/s? Guess sending data with 4 I2C implemented this way is OK, what about receiving data?
This is a I2C Mux, means that you can connect only to one I2C bus at a time. I've tested both receiving and sending data @ 100kbps with no problem. Actually, I've tested also @125kbps and it took it with no problem.
I saw, in a prevous post from you, that u had the MPU6000 I2C connection running on the PSoC5.
I have tried everything including the code you posted back then. Apparently the problem is that my PSoC cant take the bus, because my I2C_1_MasterSendStart() returns I2C_MSTR_NOT_READY.
Can u help me? How did you set up your I2C module on the PSoC?..
Sorry for being off topic, but i am kind a desperate here :) ..
You can write to me at Texton1@msn.com if you can help.
Oh sorry it was:
I2C_1_MasterSendStart() returns I2C_MSTR_ERR_LB_NAK
So for some reason I dont get an ack from the MPU6050?..
Again sorry for being off-topic.
I can help you, check your email.
I would be interested in your I2C Mux, I have a board with a whole bunch of I2C chips on which all have the same address and I had to use external circuitry to to the MUX because Creator insists on a bidirectional pin, so I couldn't just use the buit in mux.
This is a very interesting component, but I have several questions.
The datasheet for BUFOE says that yfb gets y irrespective of x only when OE is 0. You have OE permanently enabled. I do see that you have the inout pin only capable of driving low, but I don't understand how BUFOE is allowing the pin state to be read back because OE is always 1.
The other question I had was regarding the speed; why was this design restricted to 100KHz?
I was able to add 3 I2C masters to ma schematic without problems. Are you using the Fixed-Function block or the UDB-baseed components (I was using the latter)?
Welcome in the forum, Peter.
Seems as if this thread is a bit old (a few years). So when you have got an actual I2C problem do not hesitate to start a new question.
Tell us which kind (type) of board you use, what you want to control (Link to datasheet helps us a lot) and what you already tried (Project archive or workspace bundle).
