Posted on October 20, 2014 at 02:18I've copied the SDRAM hardware and software from the STM32F429 Discovery board. We've made a few boards so far. On some the SDRAM doesn't seem to work at all while on others it seems to work for a bit then get corr...
Posted on January 25, 2015 at 10:27Hi,I am running a USB MSC project on my STM32L1 board generated using the CubeMX software.I am noticing that during enumeration, the device receives a Read10 request for 16 blocks of data (each 512 bytes in size). ...
Posted on January 24, 2015 at 19:54 Hi there... Using the non-hal on an STM32F2xx, I can read/write at 3,333,333 BAUD without a problem. When I port the code to STM32F4xx, I am unable to read/write to the USART1 at the same BAUD rate - instead, ...
Posted on December 26, 2014 at 20:44Hi, We almost finish coding. But new problem we facing is how to prevent other people to copy our PCB and code? We use STM32F249-iDisco. Please help.
Posted on December 19, 2014 at 17:25Hello, Its very new for me to work with any 32 bit MCU like STM32F405, I am having a handful experiance with AVR but not with ARM. Here goes the situation where I have stucked.....I have to compute linear encoder...
Posted on January 14, 2015 at 17:51I am teaching a course on embedded programming and am having some logistics issues I am hoping someone might be able to help with here.I have taught a class using the STM32F3 before but I had a linux environment av...
Posted on January 23, 2015 at 10:27I have just gotten the PCB for my first STM32-based design, using a F072CBT6 chip. The board is only populated with the power regulator and the CPU with its surrounding passive components. I have the F072 Discovery...
Posted on January 25, 2015 at 09:02I'm experimenting with an audio ADC connected to the I2S peripheral on my STM32F401 Discovery Board. Right now I have the microcontrollers I2S interface configured as slave half-duplex mode (input only). In other w...
