Posted on July 21, 2015 at 21:24Hi , I'm driving a 1.4'' TFT LCD on STM32F4 Disco , via SPI3 . I wanted to increase the speed of writing to the LCD so I decided to use DMA. The code compiles and work nicely but still too slow and no difference can b...
Posted on January 05, 2015 at 22:48Hi,I have installed STMstudio 3.3 on win7 x64, and I have installed java x86. (http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html).When I want to run, I select ST-Link SWD,but I get...
Posted on July 15, 2015 at 01:11I'm thinking about using a STM32F030 in a slave application where a master may need to reprogram the STM32F030 via the bootloader in the field. I have had good success with this using STM32F100 parts as bootloader sl...
Posted on July 21, 2015 at 11:58Hi people I'm trying to check the atollic Ide version with an assert but I don't know how read the ide version with code. How I can read it? Thanks #atollic #version
Posted on April 06, 2014 at 06:30Hi all! I want to control 3 phase motor (I get HDD motor from old HDD), and now I can generate 3 PWM signal on 3 channels but they are same, not shift phase 120 degree! Please help me! I use STM32F4 discovery board a...
Posted on July 21, 2015 at 14:07We are using the L152 processor in a new design. This is the first time we've used the STM32 family and it is mostly working wonderfully. However, on the three prototypes we have, only one crystal oscillator works rel...
Posted on July 21, 2015 at 13:42Hi, I want to know how could I get a range 0-5V in ADC. I know that normally it's from 0-3V. It's enough connecting 5V to Vdd? Thank you
Posted on July 21, 2015 at 15:43 Hello there I've been trying to implement an IIR biquad lowpass filter with the DSP library lately. I started out by designing the filter in MATLAB and calculating the IIR parameters before I pretty much ...
Posted on July 20, 2015 at 16:58 Hi, I had to measure frequency but in a large range of frequency. the target is a STM32L I would like to realize something like : T2 generate a 10hz signal on PA0(using internal clock, and compare/match) ...
Posted on July 21, 2015 at 15:29Hi all, I have a STM32F103 and a Secure Access Module (SAM) (PCM1.1 by NXP). The SAM needs a clock input and an I/O pin to send and receive data to and from the MCU. In my design, the clock port of SAM is already conn...
