Re: MOD5213 SPI with 23LCV512 Chip

Hi Chris No, I just decided it was a good time to do something about analyzers so I ordered up a Logicport. In this instance, it didn't do any more for me than the scope. I didn't have any analyzers previously - just the scope. I wouldn't say it is better than any other model but it is fast and good...

Re: MOD5213 SPI with 23LCV512 Chip

Ordered an Intronix Logicport analyzer.

This is much better - and more fun.

Thanks to those of you who took a minute or two ...... !

Re: MOD5213 SPI with 23LCV512 Chip

Hey guys Situation: Good. Project is working almost as well as the forum !! Somewhere I read a Netburner comment about using a GPIO pin for /CS until everything is sorted out with a particular SPI project, so, after the glitch I wired up MOD5213 Pin 15 as /CS and the setup is actually operational ! ...

Re: MOD5213 SPI with 23LCV512 Chip

$149 for an analyzer - can't beat that ! After fiddling with the QSPIInit( baud_rate-in_bps, xfer_size_in_bits ....) function call, I see that there is a half cycle clk delay (stretch during low time) after the 8th clk when using 8 for xfer_size_in_bits, and the same after the 16th clk when using 16...

Re: MOD5213 SPI with 12LCV512 Chip

The chip is a 23LCV512 and not 12....... Yes, I tried pushing the data by clocking zeros into the serial in pin, and other bytes too. I am running the clock slower. Using a clock rate of 20000 is fine with the dual channel storage scope - I can roll the display back and forth and count the cycles an...

MOD5213 SPI with 23LCV512 Chip

Hi folks, Working with the above, no problem reading/writing the Mode Register, but cannot seem to read/write data. Using the Netburner QSPIInit() to access the chip as in the QSPI2Serial app. I can view data to the chip with a storage scope; see addresses, etc., but no data returned from the chip d...
