Posted on July 29, 2014 at 20:26I am trying to send an array over UART using the DMA. I dont know why the DMA does not send more than 65535 elements.Is there a restriction on the DMA for only 16Bit numbers only ? #stm32f4 #board #discovery #rtfm ...
Posted on July 29, 2014 at 21:07HiI'm trying to get the USB virual com ports working with a STM32F401 discovery board, using IAR workbench, and the code generated from STM32 Cube MX. I found this/public/STe2ecommunities/mcu/Lists/STM32Java/flat.aspx...
Posted on July 29, 2014 at 00:53Hello, I am reading from an external ADC in parallel interface(16 bits). I dont know what is wrong, only my port PE0 and PE1 are talking to the controller at 1V and rest all others taking at 3V. when I remove t...
Posted on July 19, 2014 at 13:47I am using STM32F205RBT6.I have to start a timer when a particular event happens. This I have done in programming.After that interrupts comes on three other pins. Now I have to measure the time between:1. Start & inte...
Posted on February 03, 2014 at 17:30The DFUse software package (STSW-STM32080, version 3.0.3) comes with the USB Tube driver (STTub30.sys) version 3.0.1. This driver works for me on Windows 7, but does not work on Windows 8 for me. At some point i...
Posted on July 28, 2014 at 11:51Hi everyone,I apologize beforehand if this isn't the right place to post my question, but I just started with this forum :).Anyway, I've been given an STM32L0538-Discovery board for a project and I can't seem to find ...
Posted on July 28, 2014 at 18:38Does anyone know how to embed BMP images (or other files) into the application image in IAR? I'd like to embed a series of BMP images, then have my code be able to read the BMP and send it to another device for displ...
Posted on July 25, 2014 at 18:47I have used WFI() previously, but I can't figure out what is going on with my current code. The WFI() returns immediately, but I can't figure out what interrupt is active. Any tips for determining what caused a WFI(...
Posted on July 28, 2014 at 01:25I have two different projects: one based on the '205, one on the '427, Both use identical USB libraries from ST. They are both set up as FS devices using the internal USB PHY. The issue I am seeing is that in the '205...
Posted on July 27, 2014 at 15:28When I using my desktop computer to power the STM32F429i Disco, the PWM out put amplitude is aobut 3v, but when I use a IC LM7805 (change DC form 9V to 5V) to power it, PWM reduce amplitude obviously, even just have 1...
