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 June 02, 2015 at 08:52 I'm using the FatFs library ver R0.10 to access the SD card. Here is my code: SystemInit(); USART_Configuration(); NVIC_Configuration(); /*-------------------------- SD Init ----------------------------- */ Sta...
Posted on March 21, 2014 at 10:34hello, I know that I should post this in Coocox forum, but I what to know if one of STM32 users faced this issue before: I have a strange issue with Coocox (COIDE V1.7.6), it may be a bug: - Optimization is set to -O...
Posted on May 22, 2015 at 23:48I'm reasonably competent in using CubeMX, STM32F4xx with IAR. I added the SDIO driver for micro-SD cards, via the latest HAL libraries that CubeMX utilizes. I have this ID'ing and doing read/write at the driver level...
Posted on June 02, 2015 at 02:32Hi,be warned - RM0091, as of rev. 7 (oct. 2014), has a few errors in section 19 ''General-purpose timers (TIM15/16/17) : it seems some sections were copy-pasted from another timer. Those timers *DO NOT* have a downcou...

Posted on June 01, 2015 at 22:00 Hello, I working with STM32F3, and my goal is to feed in an external voltage into COMP2 (non-inverting input) compared against another constant analog voltage (inverting input), in order to produce a calib...
Posted on June 01, 2015 at 17:09Hi all, i'm new to cortex M4 STM32F4 processor and i have some problems with external interrupt handling and internal timer interrupt. Currently i'm trying this code on a DISCOVERY F4 board (with STM32F407) and i'm tr...
Posted on June 01, 2015 at 17:07Recently designed a custom board based on the STM3220g eval board and notices the I2C lines looked very bad (long rise times). The internal pullups were enabled but the lines look nothing like the I2C on the evaluatio...
