Posted on April 19, 2017 at 19:16STM32F437I want to use ADC3 with DMA to capture values and have them available when needed but I don't need an ISR. Regardless of changing the input the value never changes. Below is the code I am using. Please give ...
Posted on April 12, 2017 at 18:23How can I use FFT on STM32F427 development board?Where Can I find arm_math.h file?Can I use void cr4_fft_1024_stm32(void *pssOUT, void *pssIN, UINT16 Nbin) this FFT function with my board?#fft-stm32f4 #stm32f427
Posted on April 20, 2017 at 16:04I'm new to STM32 line of Microcontrollers, However I have worked extensively on TI MSP430 line.I recently bought STM32L-DISCOVERY with STM32L152RCT6 controller onboard.I got the en.stsw-stm32077 standard peripherals ...
Posted on April 20, 2017 at 14:15Dear All,This is regarding the CRC checksum calculator for the STM32F446RC Controller. I am using the internal HW CRC module in F446RC to calculate CRC for UART communication protocol and sending the packet including...
Posted on April 19, 2017 at 16:54Heys everyone,I'm new to the ST Community, so hi ^^. Anyways, I'm working on with the X-NUCLEO-IKA01A1, and I'm trying to use the Instrumentation Amplifier that the X-NUCLEO Board has; therefore I went and looked for...
Posted on April 19, 2017 at 11:43In a project I'm attempting to measure 4 frequency channels (range 10 to 500 hz) using TIM3 in the STM32FDuring development I noticed the occasional missed capture event, or double capture events. I didn't pay much a...
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 ...
