External eeprom

Post by markavo »

been using flowcode 8 but instead of using the arduino testing out st-arm nucleo-f746zg

With the code working on the arduino and a channel to select from within the properties all is good for the arduino i just connect to the pins flowcode says.

But when i select the new chip F746 i only have the option for software in options and im struggling to get the eeprom to talk even though i select pins (i also have to select remap pins) and connect to them.

Any pointer please.

Hi,
Do the pins do anything? e.g. Do you have an oscilloscope to check them?
Does the board otherwise work? Can you check it with say a 1 second LED flasher program?
The "Stop delay" might need to be set to "Yes" to allow time for EEPROM writing.

Hi

Thank you for your reply, no scope sorry to check the pins.

Yes the board works fine i am talking to a Visi 4d display through its channel 1 and setup as you say to first prove out the new board was flash onboard led's that's ok.

I will check this delay later when i get back and update.
Thank you.

Hello,

The Remap pins should not be visible in software mode and can be ignored. I'll look into this.

You need to set the SDA and SCL pins to meaningful values and then hopefully it will work as expected.

Thank you.

setting the re-map pins to anything and setting the clock and data lines to suitable pins worked.. :D
