Posted on June 18, 2015 at 10:15I have a DMA channel configured to transfer data from memory to GPIOC->ODR on a PWM1 channel's CC event. This same PWM1 channel is used to read the data output on GPIOC by an FPGA. A falling edge triggers a request to...
Posted on January 08, 2015 at 13:37Hello I'm looking for a solution to get the time between to input signals in microsecond resolution. But I do not want to use an interrupt counting up all microseconds. Is there a convenient solution / method? #...
Posted on June 18, 2015 at 12:09Hello, i'm trying to develop an usb composite device(MSC+HID classes) on STM32F407 using the USB Device Library that comes with the STM32Cube. Basically what i've done is importing in import already working codes for ...
Posted on June 17, 2015 at 17:31 I am working with the Discovery development boardSTM32F407 microcontroller and building using Eclipse/GNU. I have successfully created a small application can communicate with a PC via UART4 and it has free spa...
Posted on October 25, 2014 at 23:43I want to set Readprotectionlevel=1. After the initialisation i can't see toggling of GPIO_PIN_7. The function HAL_FLASH_OB_Launch(); causes problems. When commenting out the function HAL_FLASH_OB_Launch() the whil...
Posted on April 28, 2015 at 01:37Hello Sir, I work on an evaluation board stm32f4 discovery, using ST-Link Utility v3.6 on Windows 8 with an usb connection. When I load an hex into memory, the command to run application fails with the message no ta...
Posted on June 18, 2015 at 09:25I'm looking forward to working with the STM32L4 series (hopefully in a LQFP48 package - please). It should provide a good processing boost for my low/limited current application.But I have a suggestion for future prod...
Posted on June 17, 2015 at 14:46Hi,I am using STM32F407 uc with latest HAL lib. for PWM. In th elatest lib. there is no function provided to update the Duty cycle, reset the counter and auto reload like old driver TIM_SetCounter( TIM11, 0 );...
Posted on June 16, 2015 at 17:58HiI saw lots of discussions and solutions about working with SPI3 by disabling JTAG on STM32F103 devices. But I already have problem with it.I am using SWD for program and debug the mcu with Keil and the same code is ...
