Hello,

The code size is exceeding the limit i.e. 1000 Bytes, but the project is exceeding the limit. Please remove the unwanted code from the project.

Can you please let me know how you are using SPI to communicate to the peripheral devices like the OLED display, as FX2LP does not have a separate SPI unit. Are you bit banging on the GPIOs or using UART as SPI?

Best Regards,

Yatheesh

Hello,

Please share the block diagram of your application with us for a clear understanding.

Are you adding the Max 3421e code into the FX2LP firmware?

The data field in the Program Size should not exceed 128.

Best Regards,
