Posted on July 03, 2015 at 14:14Hi everyone, I'm working with the stm32f405 microcontroller and I am trying to send some characters using a simple GPIO pin. My problem is that I have to send each bit of one character every 20ms. For that I use a ti...
Posted on July 09, 2015 at 14:02Hi everyone,I was wondering if there are any workshops from ST that can be done at home. Something like PDFs with explanations and some exercises that you can do. More specifically for the standard peripheral library ...
Posted on July 10, 2015 at 13:10When the xPortSysTickHandler is called at the moment the SPI HW block is executing a SPI communication the i get a Bus fault resulting in a Hardfault Is this a known issue? I can solve the issue by first executing the...
Posted on July 10, 2015 at 13:08Using a D/A the converter I am now able to monitor the gyroscope rotational accelration around the x axis as a voltage. I run the gyroscope at 190 Hz rate and read the oscilloscope in a thread every time the the DRDY ...
Posted on July 08, 2015 at 05:07Hello: I have an STM32F405 processor, with a 8MHz HSE crystal. It's set up to operate at 168MHz. To see if I can get suitable performance at a lower speed to save power, I'd like to change this (*not* on the fly) at t...
Posted on July 10, 2015 at 03:36Hi All,I need to transfer a large amount of binary data to my STM32 and am trying to figure out what the best way to do this would be. The data throughput needs to be roughly 4Mbps. The device has USB so I was thinkin...
Posted on July 06, 2015 at 20:17 I am working with STM32F427ZIT6 (Keil MDK-ARM 5.15) and want to implement a delay function based on Timer 6 in a single pulse mode. The delay function is: void Delay_us(uint16_t amt_us) { TIM6->CNT = 0...

Posted on July 09, 2015 at 17:28Hello everyone, I want to etablish a communciation between a STM32F0 discovery (with a bluetooth module, probably HC-05) and a computer (equiped with a bluetooth key). But i only want that the STM32F0 can be able to s...
Posted on July 07, 2015 at 17:14 Hello everybody, I face to a weird problem and any help could be decisive :) (and I will be grateful of course) I transfer a project which implement USB, I²C and SPI from STM32F407 to STM32F446 but I am...
