STM32 RTC Time lags
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...
Posted on December 12, 2014 at 02:46 Hello, I'm having an odd issue with the I2C peripheral. I have a simple routine for writing a value to a slave device register below. It succeeds writing to the slave as seen in Image #1. Following tha...
Posted on December 11, 2014 at 13:09Hullo guys , I was wondering about the frame rate of the LTDC in STM32F4xx series , There is no obvious information in the user manual about the frame rate , and in the demo example , I just set the pixel value in...
Posted on December 11, 2014 at 18:13I noticed that the touch controller is not working properly to detect presses of the touchscreen on the STM3220G-EVAL and looked further into the code. The problem appears to be rooted in BSP_TS_GetState() in the...
Posted on November 23, 2014 at 19:08I have designed a board with a microcontroller STM32F042K where SWD does not work. I connected pin 4 (NRST) with a pull-up 100Kohm and a 100nF capacitor to GND and pin (BOOT0) to GND with a resistance of 470ohm bu...
