I2C TRISE
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*...

STM32F4 PWM+DMA problem
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...
STM32F0Discovery - ADC DMA How to sort Conversion Data
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...
STM32L- how to set DAC reference voltage
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...
STM32F0 Discovery - how to connect LCD display
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...
STM32F100 RTC issue
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...
STM32 ADC protection diode
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...
enable / disable ART accelerator
Posted on September 19, 2013 at 11:43Simple question. Hard to find any information about this. In the data sheet there are tables where ART is disabled and where it is enabled. But no more information at all around the ART concept. Regards, rygelxvi
Getting ADC Data on USB using STM32F4 Discovery
Posted on September 16, 2013 at 10:04HelloI am working on STM32F4 Discovery .I have write code for ADC for STM32F4 Discovery (with FreeRTOS) and load ,debug using GNU tool-chain.Now I have to get that ADC data on another USB (i.e USER_USB port on S...
Voltage from external device on pin of STM32F205 even if vdd is off
Posted on September 19, 2013 at 07:19I am connecting a external terminal device which communicate with STM32f2. Sometimes device is shut off which remove poer from stm32 but termial device remained powered which gives high 3.3V on device, will it da...
