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 May 28, 2015 at 11:13hi in my software, define a section named ''My_SECTION'' and put just a function on it. in IAR .icf file define that section write in address 0x08050000. I used debugger, function is correctly wrote in 0x08050000 and h...
Posted on May 29, 2015 at 19:09Hi, I'm having problem with stopmode. I want to wake up uC with RTC Alarm in EXTI17.But when i use stopmode with statement PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI), it didn't wait to RTC Alarm Event...
Posted on May 30, 2015 at 00:58I am looking at using the STM32Cube libraries and eCos together. Before attempting to write the CMSIS wrapper, I'm wondering if anyone has already written this support for eCos. Specifically, I am interested in getting...
Posted on May 30, 2015 at 00:11 Hi, I'm using I2CSTM32F207ZET6. It usually works well, and we can usually read and write with no problems. However, there is a consistent error that pops up where, if we are reading a number of bytes sequen...
Posted on May 30, 2011 at 12:36hello, I have a STM32F107 and I'm programming with IAR embedded workbench. I have seen on the stm32f107 datasheet that the flash memory adress is between 0x08000000 and 0x0803FFFF. How sould I program if I want to writ...
Posted on May 29, 2015 at 21:23HelloAccording to UM1472(stm32f4discovery manual) there are 0 and 220 ohm resistors placed in crystal path to pin, why?Thanks.
Posted on May 29, 2015 at 17:43HelloHow to choose proper capacitors for a specific crystal(e.g. 8MHz)?Thanks.
Posted on May 29, 2015 at 07:17System Clock Configuration tool is doing a great job to generate init code for STM32F405RG however it does not support external clock oscillator which is fed into OSC_IN (pin 5) only. (meaning Osc not Crystal).I suspec...
Posted on May 20, 2015 at 22:51Dear community,I want to send some data via UART directly to DMA without interruption. To solve this problem I use a custom FIFO stack from which the DMA feeds itself using its DMA interrupt-routine.The stack is filled...
Posted on October 05, 2013 at 22:03Hi;I am working on the Custom HID application which is in the St library and I use STM3210E-EVAL. But this protocol transfer only 2 bytes (1 Byte Id + 1 Byte Data) so I modified the code and I transferred the 64 b...
