Stepper brick firmware size

[greijsmuis]

Hi all,

 

I would like to tinker around with the stepper brick. Im familiar with C programming of MCU.

 

I would like to hook up an SPI angular sensor to the stepper brick. My question is: How much free space is available in the brick for custom firmware? I guess the bootloader takes some space, the standard firmware is 55 kb, how much is left for development?

 

Best regards,

The microcontroller on the Stepper Brick has 128 kB flash memory. The bootloader is not stored in this flash memory. But there are 4 kB flash reserved at the end of the flash memory for each of the two Bricklets.

 

So there is currently 128 kB - 55 kB - 2 * 4 kB = 65 kB of free flash memory.

Hi all,

 

I'm planning to develop an application with the stepperbrick. I need to make a few modifications to the source code to read out an I2C sensor. I know my way around compilers/git/c code but I do run into some trouble just following the steps from firmware upgrades:

siamon, your post seems incomplete. What trouble do you have?
