I am using a Cypress 68013 and a 16 kB 3.3 V EEPROM. The fx2lib I2C functions
to read the EEPROM isn't working, but if I manually send the I2C read and write
functions as shown in the read and write EEPROM code, but with a delay in
between it works fine.
Has anyone else seen this? I am only running at 100kHz.
I am using fx2lib-src-0.1.tgz which looks like the only released version. I am
using the newest version of SDCC so I had to go through and update everything.
Didn't know about the github until already had done it.
I am just interested if there were any other fixes to I2C that I might not have
roled in or if I should just add a SYNCDELAY in my fx2lib and rebuild it.
When I check with a scope, what I notice is that without the delay the first 1
to 3 reads are NACKed. It retries and eventually gets a ACK when the part is
ready but the randomness of when it gets acked means that the data is random.
If I add the delay the first read is ALWAYS acked and the data is always good.
Thanks
Kevin
