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...
Posted on January 24, 2015 at 17:52 Hello, i have a problem with PWM. I am trying to turn on the led (PE9) on TIM1_CH1. I want to make it brighter and brighter till counter equals 256 (2^8=256) #include < stm32f30x.h > #include <...
Posted on January 21, 2015 at 09:55HI ALL I have written a code for USART communication full duplex between stm32f407 and stm32f030 and it is working fine as soon as power on reset. The half duplex communication also working fine between two stm32f...
Posted on March 29, 2014 at 19:51I am trying to toggle an I/O line to measure timing for benchmarking dsp algorithms on an STM32F407VGT. I generated the HAL using STM32CubeMX and set PD12 and PC8 to outputs and configured them as output push-pull wi...
Posted on January 24, 2015 at 07:30 An odd question, maybe, but is it possible to initialize the DMAy_FLAG_TCx to true? I have a routine that teststhis flag and then sends data, and I would like it to fall through the first time. I'd rather not ...
