Posted on October 25, 2012 at 16:25Hi. Erased state of flash memory in STM32L low-power devices is 0 instead of more common 1. What is the reason for this? If I will program unused flash portion to all FFh, will this impact current consumption in an...
Posted on October 25, 2012 at 14:38Where do I find out what DMA channel/stream i need to use for SPI1 TX.not sure which st document has this information in it?(stm32f4)Thanks :)
Posted on October 24, 2012 at 21:07Hi all,After flashing my board based on a STM32F405RG with ST link utility (Hex compiled with GCC under eclipse), I can't communicate anymore with the core. I have this error :Cannot run core while booting from fla...
Posted on June 30, 2012 at 23:43Hello, i have a small problem i think.With the help of this forum and google i created a project with CoIDE.What it should do is reading the directory of an SDCARD.The SDCARD part is working. but the fatfs is not work...
Posted on October 23, 2012 at 13:50 Hi. I am using a STM32F4discoveryboard to prototype an application. In the application, I have some really critical interrupt that must be handled (or else there will be an uncontrolled surge of over 80...
Posted on October 25, 2012 at 01:55For Cortex-M3 processors, there is a bug that prevents the event register from being set on interrupt entry or exit. This can cause problems if an interrupt occurs in an event loop before the WFE instruction is exe...
Posted on October 21, 2012 at 12:16I'm currently developing a USB host and my device needs currents up to 500mA. Can the board deliver those a) when powered by a PC over the debugger unit? b) when powered externally by its pins?

Posted on October 24, 2012 at 19:51Hi,I am using STM32F207VE, and trying to perform read/write operation. Since this chip has flash memory of 512K, not sure how the mapping takes effect. Memory mapping is explained for 1MB flash, but not for lesser ...
