Posted on January 31, 2013 at 21:24I have an application that runs fine alone when booted stand alone but appears to have timing problems when branched to through a boot loader. It appears to run slowing and I suspect timing related registers. Is t...
Posted on February 01, 2013 at 12:33Hello I’m new to the STM32 world and I’m making some experiments with the STM32F4 Discovery Board. I would like to measure the VBAT and Temperature sensor signals using the ADC1 and the DMA, continously scanni...
Posted on January 31, 2013 at 16:34Hi everyone I hope someone could confirm this: I am designing a project with STM32F407vg that must operate from battery for about 2 years in STANDBY MODE, In my system i have 2 batteries , external 12v that is r...
Posted on January 30, 2013 at 20:58Hi all,I can't figure out whether the TC flag is set at the end of a break character or not.I use a GPIO to enable TX mode on the RS485 transceiver at the end of any transmission I normally monitor the TC flag and ...
Posted on January 30, 2013 at 02:19Hello, i need connect HY28A with ILI9320 to my STM32F4 Discovery, but i didn�t find any examples on whole internet. I spended many days to try start SPI connection and connect GLCD, but without any success.And hav...
Posted on January 29, 2013 at 18:04Hi everybody,I wanna know if its possible to use DMA SPI for drive the ADS1256 or similar where I can ''stop'' the tranfer to wait until the time to convert T6 (Delay from last SCLK edge for DIN to first SCLK) of t...

Posted on January 24, 2013 at 07:53I've noticed that STM32L initializes Flash to 00 instead of FF. Yes, it has an EEPROM section that can be used for 4KB of NV data storage, which is great. I suspect that is actually NOR Flash as well.Anyway, if S...
Posted on January 31, 2013 at 13:38 Hi, I have a problem for the second time, I don't know why but hardware breakpoint, sometimes, still in stm and I can't delete it. I use OpenOCD 0.6.1 and gdb This is my gdb log : ...
Posted on January 31, 2013 at 13:06Trying to get a linux toolchain up and running to eventually program an STM32L Discovery board. I have Code Sourcery CodeBench Lite set up in a folder and a Make script set up to build it all. Right now it's just...
