Hi,I am using Quartus II (v14.0). Using the IP Parameter Editor i have created a altera_ufm_i2c with settings: Access mode: read only Address MSB: 1010 Memory size: 4k currently initalized blank (all 1's) but will be init from file eventually. (am also a bit unclear what the file should look like (HEX), but that's a different question) This is then instansiated in my main code block. I am able to do a loop-back test over i2c so am confident the IP is correctly in my code. My question is: what is the protocol to read the ufm over i2c from a given memory location. On other devices i've used the process is normally: start bit / device address (1010-000-1[w])/ 16bit off set
start bit / device address (1010-000-0[r])/ ... and the location is read from the offset memory olocation over i2c I have tried the following links but no luck so far: https://www.altera.com/en_us/pdfs/literature/ug/ug_alt_ufm.pdf https://www.altera.com/en_us/pdfs/literature/an/an489.pdf Any help much appreciated.
Looks like what I was looking for is in here:https://www.altera.com/en_us/pdfs/literature/hb/max2/max2_mii51010.pdf page 16 onward 4-Kbit Memory Size MSB LSB 1 0 1 0 A2 A1 a8 R/W For the 4-Kbit memory size, the A0 location in the slave address becomes the MSB (a8) of the memory byte address.
