MSP430FR2355: How to create an undefined/variable array

Hello,

I think the customer is asking if they can dynamically size an array. While it may be possible, I wouldn't recommend it. In our I2C code examples, you'll see there are several arrays of different sizes. This way, depending on the command, the appropriate array size can be used without having to size it dynamically.

#define SLAVE_ADDR  0x48

/* CMD_TYPE_X_SLAVE are example commands the master sends to the slave.
 * The slave will send example SlaveTypeX buffers in response.
 *
 * CMD_TYPE_X_MASTER are example commands the master sends to the slave.
 * The slave will initialize itself to receive MasterTypeX example buffers.

uint8_t MasterType1 [TYPE_1_LENGTH] = { 8, 9};
