STM32F334: HRTIM DMA Transfer error when send to CMP1xR register

I try to modulate a sinus signal with the PWM of the HRTIM.Therefore i had used a table of 16 points, the PWM freq. is 640Khz and on the PWM output (TA1 of timer A).After a RC filter i becomes a sinus signal of 40KHz. The DMA send on every TA1 set, t...

Issue with STM32F302CBT6 I2C and 24LC512 EEPROM

Pull down PA1

hi thereI have a project with STM32f103c8t6 blue pill. here I connect a 12pF capacitor to pin PA2 and PA1. PA2 is GPIO_OUTPUT and PA1 is ADC.first: PA2 is set HIGH to charge the capacitor and then goes LOW right afterwards. here is my while(1) codetu...

stm32f4 spi dma circular mode for external ADC 2M Sampling

hi,i'm trying to read the external adc value using spi1 + dma (MAX11198ATE+)i though it works fine but, sometimes it returns wrong values i have checked the waveforms of SPI MISO/MOSI, SCK (hardware)but there was no error forms. it seems to be matche...

Using BDMA2 on a timer to control a GPIO port using a STM32H7

I feel that CubeMx and HAL will reveal no solution to this but I still would like a solution to this problem. The GPIO pins on the H7 are on the AHB4 bus, as is BDMA2. I wish to set a timer to cycle through a buffer toggling a GPIO port outputs. Is t...

How can I stop PWM signal?

I'm generating a PWM signal inside a loop, but I can't stop it. What would be the reason? I need both to generate PWM and channels. HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_1);HAL_TIM_PWM_Stop(&htim3, TIM_CHANNEL_1);HAL_TIM_PWM_Start(&htim14, TIM_CHANNE...

BLE Beacon example in BlueNRG-2 does not work?

I downloaded the BLE Beacon / Relase example from BlueNRG-1_2 DK 3.2.2 into eval board STEVAL-IDB008V1M by BlueNRG-2 Navigator.I do not see this BlueNRG BT device in laptop although a serial console on VCP shows that all functions passed with success...

Are there HAL functions to generate DMAMUX events?

I'm programming an STM32L552, and I've used HAL functions to configure DMAMUX synchronization. There's a field that enables DMAMUX events, but I haven't found any functions that generate DMAMUX events.According to the documentation, "The DMAMUX may a...
