Hi everyone,
I am using the TMS320F28027F for controlling 4 stepper motors. I want now to implement a kind of " stack of instructions" in order to implement fluid synchronised movements of the motors. Basically a stack of instructions that it must be saved and execute in order when the user sends the START command.
Each instruction has 40 bytes, so in the moment the user want to save several instructions (several movements of the motors) I am run out of RAM and I have thought to use some of the blocks in FLASH memory.
Is this a professional solution? It is the first time that I have to use a lot of memory for a MCU application. I need large store capacity and being very fast to retrieve the data so the saved instructions (movements) can be executed without perceptible delay.
I chose TMS320F28027F because the PWM capabilities that I needed for the stepper motor control but not thinking in the memory capacity. Should I upgrade to a bigger MCU? which one?
Best regards
