I need to generate two phase shifted asymmetric clock signals.This should probably be done using Combined PWM mode.What I need Basic clock in TIMx_ARR for simplicity 4MHz , pin 1 with PWM1 , pin 2 with PWM2Clock 1 2 3 4 1 2PWM1 1 0 0 0 1 0P...
I have declared my SPI2 base address:#define PERIPH_BASE 0x40000000U #define APB1PERIPH_BASE PERIPH_BASE #define SPI2_BASEADDR (APB1PERIPH_BASE + 0x3800)I have a SPI Handle structure:typedef struct{ SPI_RegDef_t *pSPIx; //This holds the base addr...
I am using STM32G071RBTx on our custom boards. The controller is connected to a Beaglebone Black over SPI. The STM32 controller is working as an SPI slave and the Beaglebone as the master. There are not CS lines defined for the communication. FreeRTO...
Hi! I know overall idea of DMA and i need to use it but i have no idea how to do it. I found one post with same question but i didn't found any helpful info for me. I'm not advanced in case of using registers. I used them to directly change CCR and A...
Hi,Our application of the touch sensing controller is a three zone capacitive sensor with the left and right sides connected it the form factor of a 4 zone with three signals. We have it placed along the surface of some black plastic that is meant to...
I'm currently using NUCLEO STM32H745ZI-Q.I am trying to use the expansion board X-NUCLEO-IDB05A1, it is a Bluetooth module.Does anyone know how can I build a Bluetooth connection between the board and a smartphone?
Using a Nucleo f401re nucleo board with a 'X-NUCLEO-IHM03A1' shield that houses a powerSTEP01 stepper motor driver. I've downloaded and run the example projects from 'X-CUBE-SPN3' by ST and the stepper motor runs perfectly. I then generated my own pr...
Hello to everyone,I am developing an indoor sensor system using a ST microcontroller. The hardware used includes a battery power supply, an analog sensor and a radio transmission part. Assuming that I produce more pieces of the sensor, I would like t...
Am using NUCLEO-STM32H723 Nucleo-144 board.Sorry, but I have no experience with the above MCU/TIMx.My goal is to measure external frequency as accurately as possible.I'm interested to know how to Link between two timers.Example : TIM3 ( Master ) TI...
