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 January 13, 2012 at 11:42Concerning the NVIC interrupt handler: I am a bit curious, how NVIC manages to keep log of the multi-load commands, if several interrupts would interrupt one each other. As far as I understand it, STM32 has 16 leve...
Posted on January 12, 2012 at 13:30There is a part of codes in the stm324xg_eval_audio_codec.c. /* CODEC_I2C SCL and SDA pins configuration -------------------------------------*/ /* If the I2C peripheral is already enabled, don't reconfigure it *...
Posted on January 14, 2012 at 02:31Hi, On UM1472 - STM32F4DISCOVERY User Manual, page 27, says pin PE2 is connected to CS_I2C/SPI of LIS302DL. On schematics (page 30 and 35) the pin connected is PE3. Anyone knows what is the correct pin? Best regar...
Posted on January 13, 2012 at 14:56I can't figure out how the PRIGROUP is initialized in the stm32. In PM0056 (Programming manual) it appears the SCB_AIRCR register field for PRIGROUP is initial 0, but the table defining PRIGROUP (table 45) has no...

Posted on January 11, 2012 at 01:31It's strange, I don't have a transmission with this function and I don't know why. State of registers after USART_Cmd(USART1, ENABLE) is: SR -> 0x000000C0 (OK) DR -> 0 BRR -> 0x00000683 (for HSI = 16 [MHz] -> OK) C...
