Posted on September 18, 2013 at 21:21Hello. Could some one help to solve a problem with ITM on STM32? I try to use ITM to log data, but some data is missing every time, may be some buffer is overflowing I don't know. I also try different STM32 contr...
Posted on August 18, 2013 at 12:07Dear All, We are using STM32F207ZGT6 in our product which is used for CAN & Ethernet communication.Recently we observed one issue in our board.Board will goto non working condition suddenly and if we connect ST link...
Posted on September 18, 2013 at 20:05Hello guys, unfortunately I observe very odd behavior with ADC on the Discovery board. In my hardware setup i have only a power supply to generate the voltage for ADC and I have soldered a 2.2nF capacitor on the...
Posted on May 01, 2012 at 07:54 I would like to understand what the I2C TRISE register does. The standard peripheral library effectively sets it to either: I2Cx->TRISE = PCLK1 / 1000000 + 1; or I2Cx->TRISE = (PCLK1/1000000*...
Posted on September 19, 2013 at 08:30 Hello, I've been trying to set up a 800kHz PWM signal with its duty cycles being transfered via DMA to the capture compare register. Well, it just doesn't work, not a single transfer is happening and I j...
Posted on September 13, 2013 at 17:14Hi, I am using the STM32F0Discovery board and I am acquiring ADC converted data value using the DMA. Well, I am able to read values but I cannot understand how the uC fills the Buffer. I am using a buffer[5] beca...
Posted on September 18, 2013 at 00:22Hi all,I'm working on STM32L-discovery board and currently I'm trying to configure two analog outputs with DAC. I am able to see the result from the output pin but there seems to be some bias from the zero refer...
Posted on September 19, 2013 at 16:52Hello everyone,I have a problem with connecting STM32F0 Discovery board with Hantronix HDM16416H LCD display. I don't know which STM32 pins should be chosen to connecting STM and Hantronix LCD 4x20 display proper...
Posted on September 19, 2013 at 15:57Hi all,I have trouble with RTC on STM32VLDISCOVERY board.After initialization, when I'm calling RTC_WaitForLastTask() after RTC_SetCounter() function, the MCU falls into an infinite loop.I can't get what is wrong...
Posted on September 18, 2013 at 11:58Hello,I want to protect my ADCs from overvoltage and ESD, and limiting the input to 3.3V.This is my schematic:There is a voltage divisor to convert 5V > 3.3V. The top resistor is also used as the diode resistor...
