Posted on April 20, 2017 at 16:44We have a custom STM32F769 board with a Lithium Manganese Dioxide CR1220 non-rechargable coin cell connected to Vbat. We are concerned that there may be an issue with this as there is no reverse charge protection cir...
Posted on May 04, 2016 at 19:29 I am implementing FatFs and MSD on SD Card using HAL libraries from STM32CubeMX.Everything is working perfectly but only if I not set up a DMA for SD card. It get stuck in while loop: /** * @brief SD DMA tr...
Posted on April 20, 2017 at 13:42I'd like to use the LSE to clock an internal Timer. I had this implementation in some L1 devices, but I think this feature is missing with F7. With L1 I had TIM10 with ETR2 as clock souce + ETR remaped to use LSE.In...
Posted on April 16, 2017 at 17:39Thank you for your patronage. Please tell me how to calculate the dead time or determine dead time in this figure. I understand thatHCLK = 84MHzPrescaler = 83Counter Period = 99Pulse = 20Dead Time = 150so frequency ...
Posted on April 13, 2017 at 09:10Dear Community,to realize a nearly ideal low pass (without phase shift) – filter I need to perform a symmetric running average operation using the STM32F4 core. This operation takes 3000 sampled points of raw data an...
Posted on April 18, 2017 at 05:08Thank you for your patronage. HRTIM does not work. I set up config as shown below.And, I wrote a program as shown below.But HRTIM does not work. #hrtim
Posted on March 22, 2017 at 22:46Hi,I'd like to report a potential bug in the code generation / clock initialisation code for the STM32F103c8t6.Cube version 4.2STM32CubeF1 Release 1.4.0Keil uVision 5.22I have attached the very simple project and cub...
Posted on April 20, 2017 at 10:55Dear Community,I want to use the arm package: arm_cfft_radix4 to perform a 1K FFT repetitively in a loop on a STM32F407 device. To do so I predefined: __FPU_PRESENT=1,ARM_MATH_CM4 and added the library arm_cortexM4lf...
Posted on April 19, 2017 at 15:45I am trying to use SDRAM (42S16400J) and NOR flash (M29W256GL) with STM32F429. With the code I generated with STM32CubeMX, Flash and SDRAM are working without problems. When I add USB-FS-OTG (device) to the project, ...
Posted on April 19, 2017 at 07:11Dear All,This is regarding the Timer 1 counter mode issue that we are facing with STM32F446RC microcontroller. We are trying to use F446 Timer 1 to count the external clock pulse by configuring timer 1 slave mode to ...
