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 <a href="http://www.ebay.com/itm/USB-To-RS232-TTL-PL2303HX-Auto-Converter-Module-Converter-Adapter-5V-3-3V-Output-/330773355467?pt=LH_DefaultDomain_0&amp;hash=item4d03a0dbcb" rel="nofollow">http://www.ebay.com/itm/USB-To-RS232-TTL-PL2303HX-Auto-Converter-Module-Converter-Adapter-5V-3-3V-Output-/330773355467?pt=LH_DefaultDomain_0&amp;hash=item4d03a0dbcb</a> connected to USART1. </p> http://forums.leaflabs.com/topic.php?id=5206#post-17806 Fri, 28 Sep 2012 07:47:32 +0000 ventosus 17806@http://forums.leaflabs.com/ <p>procedure for (1) can be found here <a href="http://leaflabs.com/docs/bootloader.html" rel="nofollow">http://leaflabs.com/docs/bootloader.html</a> </p> http://forums.leaflabs.com/topic.php?id=5206#post-17697 Fri, 28 Sep 2012 03:47:04 +0000 Anonymous 17697@http://forums.leaflabs.com/ <p>Thank you ala42.</p> <p>The answer of you question no. 1, I don't know why do I want to do this. Just asking to know the procedure.

How to do this with the board? For example data logging.</p> <p>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. </p> <p>Best regards. </p> http://forums.leaflabs.com/topic.php?id=5206#post-17276 Thu, 27 Sep 2012 12:10:16 +0000 ala42 17276@http://forums.leaflabs.com/ <p>To 1) You can, but why do you want to do this ?<br /> 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.<br /> To 3) On which device do you want to use the FAT32 ? </p> http://forums.leaflabs.com/topic.php?id=5206#post-16121 Mon, 24 Sep 2012 10:26:44 +0000 Anonymous 16121@http://forums.leaflabs.com/ <p>Hello,<br /> 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.</p> <p>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)?</p> <p>2. Can I use Maple board as USB slave device? On PC I want to read the GPIO status. Is there any example code?</p> <p>3. Is there a FAT32 filesystem for Maple?</p> <p>Thank you in advance.</p> <p>Best regards. </p>
