LP5569: Unable to load data to SRAM ?

6506321
Prodigy 10 points
Part Number: LP5569

Following the sequence mentioned in your Example code we are unable to load to SRAM that we are running on a custom board(MCU MSP432)

  • Can anyone list the sequence of register write to load program and enable the engine  after loading program
  • If i2c auto increment is enabled can we write in one byte mode(start -- finish) (start -- finish)
  • How should you write the program memory in one byte mode or two byte mode (start -- next data - next data -- ... ... -finish)
  • Can we program load custom board using your GUI interface

     Hi,

    could please check the communication status between MCU and device?

    "Can anyone list the sequence of register write to load program and enable the engine  after loading program"

    -Yes. the sequence of instruction can be design by yourself.

    "If i2c auto increment is enabled can we write in one byte mode(start -- finish) (start -- finish)"

    -Yes, you can.

    "How should you write the program memory in one byte mode or two byte mode (start -- next data - next data -- ... ... -finish)"

    -in the reference EXAMPLE CODE, when enable en_auto_incr the following instruction can achieve the function.

    MAP_I2C_masterSendMultiByteStart(EUSCI_B1_BASE,0x50); //send register address
    for(i=0;i<32;i++)
    MAP_I2C_masterSendMultiByteNext(EUSCI_B1_BASE,table_32[i+j*32]); // send register data

    "Can we program load custom board using your GUI interface"

    -please provide the schematic and which MCU do you choose , then i will help tp check the function.
