STM32F3 Discovery next steps?

Hi,

I successfully setup IAR 6.5 and got the F3 Discovery Bd. demo working along with modifying the code to change the LED timing. I read through UM5170 User Manual. I'm looking for more examples to learn about the peripherals. So, I downloaded the AN4157 firmware examples. This includes brief descriptions of each peripheral but not the tutorials to work them.I also found examples with, ''This example has been tested with STMicroelectronics STM32303C-EVAL (STM32F30x)  evaluation board and can be easily tailored to any other supported device and development board.'' However, it doesn't explain How to do this.Since I'm new to ARM and 32F3, I would appreciate what next steps to learn this platform.Thanks! #stm32f3-iar #adc #discovery-board #:-discovery-board-stm32f3

Hi cilve;

I would like to store my data in memory when the computing is done and used the data for the next use. I don't have the EEPROM memory on my STM32F3, can i use the flash as an EEPROM? Thanks in advance for any help

Is that a design oversight, or you just don't want to attach one? You could, however it is not designed for frequent, or multiple writing. Writing and Erasing Flash will cause the processor to stall quite significantly if you are also executing code from it. ST has some EEPROM emulation examples, but they are not really designed for large structures.

In theory yes, but most probably not. See the datasheet for FLASH erase/program times, which is in the millisecond range. For a higher data rate, you can evaluate serial SRAM/NVSRAM.
