Posted on March 25, 2013 at 10:46While playing with some benchmarking code on STM32F4, I came across an interesting phenomenon: I was changing the FLASH waitstate in the LATENCY field of FLASH_ACR register, and sometimes the subsequent code run at a...
Posted on March 24, 2013 at 20:27hi,i am trying to send data from accelerometer to pc using virtual com port ,but when i open hyper terminal to check if data was sent i found out unsignificant symbols!!!this is the systick handler wich is called wh...
Posted on March 24, 2013 at 18:01I quite enthusiastically purchased an http://www.st.com/web/en/catalog/tools/PF252419 quite recently, and when I initially unboxed the board, I hooked it up to my Mac, and the already programmed in demonstration was ...
Posted on March 22, 2013 at 17:47I have a requirement to connect an STM32F103RB to existing equipment which is designed for interfacing with another microcontroller, with some intrinsic incompatibilities in the connection lines. I would like to know...
Posted on March 21, 2013 at 18:06 float hypo2; int32_t XH=0,YH=0,ZH=0; ............... hypo2= (XH*(XH*1.0) + YH*(YH*1.0)); hello forum, in the above code XH and YH are 32 bit integers hypo2 is float variable becouse ...
Posted on March 22, 2013 at 21:32Hello!I can't enable the interrupt (NVIC_EnableIRQ (TIM1_UP_IRQn)) from the timer TIM1.Keil dislike arguments TIM1_BRK_IRQn, TIM1_UP_IRQn, TIM1_TRG_COM_IRQn:Main \ main.c (124): error: # 20: identifier ''TIM1_UP_IRQn...
Posted on March 22, 2013 at 21:24Hi, I am having some troubles getting EXTI0 working properly with GPIOA.P0. At present, the interrupt works, just in the wrong way. I have a push button hooked up to GPIOA.P0 that pulls it to ground. It is configu...
Posted on March 21, 2013 at 19:44I have an application where I have a digital mic/codec (maxim codec chip) combination transmitting PCM 16-bit samples over I2S to an STM32F217. I am trying to use DMA to capture this audio stream, however I only wish...
Posted on June 26, 2012 at 18:36Hi to all,I started to develop a STM32F4-Discovery Soft Synth. A video showing it's first beta release is here: http://www.youtube.com/watch?v=4JkhzH57Je4In some post I view a interest to audio application using STM3...
Posted on March 22, 2013 at 00:42I am holding an STM32F205 in reset (NRST pin low). I am measuring the current into VDD1-4 plus AVDD at 1.7mA. I am using 3.3V. 0.1mA I can explain through the pull-up resistor on the NRST pin per datasheet. 0.3mA I [...
