STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on August 07, 2012 at 14:29We are working on a project in which we write some data on to a dual port RAM and we read back the same during various instants of time. When we run the program in debug mode it works perfectly fine. But when we fla...

Posted on August 01, 2012 at 18:11Hi All, I have developed a PCB that contains an USB3340 and a STM32F407, using the: STM32_USB-Host-Device_Lib_V2.1.0. But is allways working as a FS device instead of a HS one. I have tried the same code in the STM3...
Posted on May 23, 2012 at 18:47At a high level, I'm able to get I2C on the STM32F4-Discovery board working with our part (MAX5418), but there's one problem I'm having, and that is that I have to write commands twice in order for them to be received....
Posted on August 07, 2012 at 19:42HelloI dont know why, but when I use FFT code, STM32F103RBT6 just stop running in totally different part of code - mostly in parts of STD library where asserts are defined. So I think it can corrupt memory or someth...
Posted on August 02, 2012 at 22:05Wondering if anyone in the forums has made an fprintf function or equivalent? I got characters spitting out to hyperterminal, now just trying to figure out to spit out variable info to the screen.

Posted on August 08, 2012 at 16:31I have used external interrupt 0, 8 and 9. Before enabling the interrupt i have written the following codes: EXTI_ClearITPendingBit(EXTI_Line8); EXTI_ClearITPendingBit(EXTI_Line9); The interrupt is only called by to...
Posted on August 07, 2012 at 15:13 Hi, I have problem with USART1 interrupt implementation. In pooling mode, everything works, but when I try to setup interrupt, there's nothing on the output? How to enable USART1 interrupt? Do I need ...
