greijsmuis Geschrieben May 8, 2013 at 09:00 Share Geschrieben May 8, 2013 at 09:00 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?

photron Geschrieben May 8, 2013 at 09:46 Share Geschrieben May 8, 2013 at 09:46 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.

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: Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
