Posted on December 11, 2014 at 20:07Setup: I used CubeMX to generate and added code to blink 2 leds and compiled with IAR Embedded. LEDs are connected to PB3 and PB5. I have several boards I soldered 042's to with proper caps, and leds with current ...
Posted on December 12, 2014 at 15:27Hi all,I am new to this STM32 chip and I was checking out the datasheets and the CubeMX tool and I noticed something weird.http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00102...
Posted on November 24, 2014 at 15:13Hi,I'm using STM32l151rbt6 MCU. But after few days of running the program the internal RTC starts lagging. I'm not doing RTC calibration. Any other possible reasons?Thanks. #stm32 #rtc
Posted on December 12, 2014 at 08:57Hello forum, I have a weird issue with TIM's pending bits (I mean Cortex-M3 pending bits): they are set after enabling the overflow interrupt: void InitTIM4() { TIM_TimeBaseInitTypeDef timer; TIM_TimeBaseStruc...

Posted on December 12, 2014 at 08:53I am migrating code from STM3210x to STM32F0xx. major part of the application uses spi interface. I see in logic analyzer each bursts of 16bit clocks. while I expect it to be 8bit clock for each byte and a delay o...
Posted on December 12, 2014 at 02:58Hi there, STM32CubeMX looks like it will be quite nice. Where are the example files?I don't see any example files anywhere.I'd love to see examples of:* basic gpio interrupt usage* DMA to/from I2S/serial port (...
Posted on December 11, 2014 at 03:32 Hi, I ma currently trying to use the timer capture to measure a burst pulse but it always seems to miss a couple of signals. I have measured it on an oscilloscope and I can see 10 pulses but from my f...
