Posted on July 30, 2017 at 10:48Hi,I set two F303VC Discovery boards with the same configuration using cubeMx: they have same clock on apb2 bus and time segment 1 and 2 and RJW are both the same.One is programmed as a receiver and the other as a tra...
Posted on July 31, 2017 at 16:09 I'm using the PWM function of TIM4, on an STM32F429, to control an RC servo. This requires a pulse between 0.6 and 2.4 msec, at a rate of about 50Hz. Everything works fine, if I don't need to change the pulse durat...
Posted on July 31, 2017 at 13:56I made a mistake when designing a PCB for an STM32L152RE (the 64 pin variant) - I had thought the VDDA pin was the voltage reference for the ADC, so I wired this to an accurate 3V reference supply. My main supply is 3...
Posted on July 28, 2017 at 14:40It appears from the (rather lacking) documentation that the DMA Double Buffer Mode is only a Peripheral to Memory transaction. Is this correct? Or can I use double buffering from memory to peripheral?
Posted on July 31, 2017 at 04:42Hello,I currently designing a board using STM32F469BETx and two SDRAM ICs. I would like to know if ST provides any guidelines or application notes for FMC wiring and connections to the memories?Thank you.#fmc #stm32f4...
Posted on July 28, 2017 at 10:03Hello, I have a working program running on STM32F072R8 CPU that works with external device and gets data via external interrupt (EXTI4_15_IRQHandler function). The collected data is forwarded later via USB port to com...
Posted on July 28, 2017 at 14:50I am trying to use STemWin 532 on a STM32f467 board. I created a framewin with 4 buttons using GuiBuilder and ran the application, but the display is scrambled. This is how a framewin with 4 buttons looks like on my d...
