Posted on April 04, 2014 at 12:36Hello,I'm working with a STM32F427VI (256kb of RAM), I use Coocox and FreeRTOS. Do you kown the easiest way to monitor in real time the RAM memory used and free in my uC ?Thanks !Jean
Posted on April 11, 2014 at 14:46Hello Together,I have a problem with my ADC. I tried to search through the Forum but I couldn't find a similar problem.My plan is to read 6 different Analog Digital Channel on STM32F407 therefore I use ADC1, ADC2 and...
Posted on April 14, 2014 at 21:23Hi all, i'm dissapointed from transfer speeds on STM32F407 @ 168MHz core, i'm measuring roughly 10.7MHz using FSMC with the code: runTIM_stoptime();do{ hh=fsmc_read( 0 );}while( (ui32--) > 0 );stopTIM_stoptime();USA...
Posted on April 14, 2014 at 11:33I am now using a Cortext-M3 chip(STM32F) to control Stepping Motor in an industrial equipment (Only generating pulses and direction signal to send to a stepper driver). Its maximum frequency is 72MHz so I can't add m...
Posted on April 15, 2014 at 01:51I have a STM32F030 design which I migrated from a STM32F051 design. When I read documentation on the programming interface, it specifies SWDCLK, SWDDIO, and NRST. I noticed however that the Discovery board has anot...
Posted on April 03, 2014 at 16:26Hello guys, I've started reading about STM32F429 and start thinking - if it would be possible to use LCD-TFT controller in such situation:microcontroller reads BT.656 video signal (8 or 10 bits in parallel + CLK), d...
Posted on April 14, 2014 at 13:08Does anyone know the easiest way to disable USB? I have a bootloader which makes use of the usbh to download a program from a usb flash drive to flash and then runs the program. The program also makes use of usb thou...
Posted on April 13, 2014 at 18:23Hi all,I have problem about setting baud rate of USART1 to 3200000 or 3686400 or 4000000. To be able to setthe higher baudrates, I revised my RCC_Configuration() as:ErrorStatus HSEStartUpStatus; /* RCC system reset...
