Posted on June 26, 2017 at 04:33I need help with the integrated CANBus controller on the NUCLEO STM32F302R8. We are using STM32CubeMX to generate our setup code with the STM32Cube_FW_F3_V1.8.0v Firmware package provided by ST. We are then using the...
Posted on July 23, 2017 at 08:26Hi,My application uses and STM32F405. The power supplies are very stable, based on a design I have used in other applications. Dittio for the other hardware peripherals and reset circuit, etc. I have used the 405 in o...

Posted on April 10, 2017 at 12:16Good morning,Did you found the way to solve this? I'm trying to also implement RunTime DFU via USB port. Did you suceeeded? Which is the best example to follow?Best regards.
Posted on July 23, 2017 at 03:18Hey All,I'm a bit at my wits end here trying to debug a pesky issue I'm having with a very basic interrupt mode UART transmit. The issue is that when I call HAL_UART_Transmit_IT(), it causes the whole chip to lock up....
Posted on July 23, 2017 at 10:57Hi!when I tried to run the code below at an interrupt it took 123u sec! (I measured that by toggle PGIOB7) which is too big for me . any one can advice?I am using STM32F429 running at 70MHz (I can't increase the clk f...
Posted on July 23, 2017 at 16:18Hi all , I used BlueNRG-MS found a problem , the MCU is freescale chip and used SPI communcation with BlueNRG-MS , but the MCU send the configuration information to BlueNRG-MS , start I could read 0x04 0xFF 0x03 0x...
Posted on July 23, 2017 at 10:33Hi there,The idea is to use the same driver pins for PMSM(FOC based) and BLDC(own library) motors. FOC SDK 4.30 allows to initialize the same pins for only one type of motor (PMSM in my case). Is the any way to stop/d...
Posted on July 20, 2017 at 06:22Hello,I want to interface STM32F405 with Atmel memory chip AT45DB041.In which i want to send hex commands and character array for write and read.which API is most suitable for this application.When i tried send a hex ...
Posted on July 17, 2017 at 12:37HeyI'm using stm32f103c8 and I want to use all of the GPIOB .it work good expect pin 3 and 4.Those pin use for sys_njtrst and sys_jtdo-tracswo but i just use SW and i don't need these pins for programming and want to...
