   Hello,
   I am new to Maple/ARM. I did some programming with Arduino/AVR and PIC. Now I am interested in ARM. I have some questions about Maple board. I hope experienced users here may kindly help me to understand this.

   1. Like how can I program it without using the bootloader way. I can compile an Arduino sketch and upload it using USBASP avr programmer. Arduino builds and stores the hex file in %TEMP% folder. What kind of programmer needed to do the same for Maple board? Is it possible to do this with STM32 Discovery Board? And which software is needed to program (like avrdude)?

   2. Can I use Maple board as USB slave device? On PC I want to read the GPIO status. Is there any example code?

   3. Is there a FAT32 filesystem for Maple?

   Thank you in advance.

   Best regards.

   To 1) You can, but why do you want to do this ?
   To 2) Libmaple supports a USB virtual comport and works as slave device, so you can use the standard read and print functions you would use on a serial port.
   To 3) On which device do you want to use the FAT32 ?

   Thank you ala42.

   The answer of you question no. 1, I don't know why do I want to do this. Just asking to know the procedure. Say, I may erase the bootloader accidentally, then I would have to do this.

   There are adapters for STM32 - http://www.wvshare.com/column/STM32_Adapter.htm and after developing something on Maple Board, how to use the code on another blank chip?

   I want to use SD/MMC card with FAT32 filesystem. How to do this with the board? For example data logging.

   It would be good to know the specific benefit of Maple board over Arduino or PIC, like 12 bit ADC, camera interface etc. which this has while others not. As there is learning curve for any new chip, I wanted to be sure beforehand, considering there are other dev boards too.

   Best regards.

   procedure for (1) can be found here http://leaflabs.com/docs/bootloader.html

   The STM32 CPUs have an built in bootloader. The only thing you need to flash it in circuit is a TTL serial line, e.g. with a cheap USB-TTL serial converter like http://www.ebay.com/itm/USB-To-RS232-TTL-PL2303HX-Auto-Converter-Module-Converter-Adapter-5V-3-3V-Output-/330773355467?pt=LH_DefaultDomain_0&hash=item4d03a0dbcb connected to USART1.
