Posted on June 25, 2014 at 11:55Hi,I'm using an STM32F4 and have configured IOs as pwm outputs with internal pull down. These pins have been connected to an input of another chip which has a 5V pull up on its inputs. After some time the processor br...
Posted on June 17, 2014 at 11:31Hi all,I'am using USB device CDC class to communicate datas with a host. But I've a strange problem. (I'am using the STM32F429i Disco platform)The STM32 code create a memory area with 00 01 02 03 04 ... datas and then...
Posted on June 24, 2014 at 21:06Hello, I am using the STM32F4 discovery board. I have a project in which I have a timer which generate an interrupts @ 100Khz. In the ISR it stores a new value to a variable. Now how can I use the DMA to ...
Posted on June 25, 2014 at 15:47Hi,Using STM32F405RGTx, pin 64 is labelled PDR_ON while datasheet contains VDD.Which one is the correct one ?Thanks.
Posted on June 25, 2014 at 17:29ST’s new microcontroller http://www.st.com/web/en/catalog/mmc/SC1169/SS1576/LN1820 simplifies transition to energy-efficient digital power supplies by providing all the major power-control functions in a single chip. ...
Posted on June 25, 2014 at 15:07I'm sure that this is a really silly question, but is there actually a reference manual for the STM32F401 chips? I can't see one on the design resources page. The STM32F401 Discovery documentation refers to ''RM0344''...
Posted on June 18, 2014 at 14:34Hi Everyone In my project, I need to capture 6 channel ADC signals in Regular Simultaneous Mode. for that, I just started for 2 channels (Channel 0 in ADC1 & Channel 1 in ADC2). Since it does simultaneous conversion, ...
Posted on May 28, 2014 at 07:31We are using the controller STM32F427ZIT6 from ST in our design. As we are using the NRST pin for processor reset in our older design(Atmel AT91FR40162S-CJ) we are trying to Bypass the Internal Reset circuitry of ST.In...
Posted on June 22, 2012 at 20:42I have nearly got a custom bootloader working which downloads code using RS485 and is encrypted using xtea. I have done the following: 1. Recompiled the original program with the start address as 0x8003000 defined in ...
Posted on June 24, 2014 at 17:07 Hi, i recently started a school project regarding orientation using MEMS sensors. I own a MPU6050, and a fusion alrogithm already known developed by Sebastian Madgwick. Here is my code, and i will...
