I need a accurate time source for time synchronisation between boards and timestamping of sensor data so want to add a accurate HSE. I'm currently considering a 7N-26.000MBP-T 26MHz TCXO connected to OSC_IN. I would have a 10nf bypass capacitor and d...
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...
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...
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...
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...
I'm trying bus monitor mode because I want to monitor CAN communication (it doesn't return ACK itself).environment STM32H743I-EVAL and self-made board STM32CubeMX 6.3.0 Keil uVision5Source excerpt hfdcan-> Init.FrameFormat = FDCAN_FRAME_CLASSIC; ...
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...
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...
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...
