Generate PWM N-Pulses with each different Pulse width

We need to trigger camera by using PWM with different trigger delay for each photo. i.e trigger the camera at 100ms, 120ms, 150ms, 200ms, 210ms, 240ms, 260ms, 280ms, 300ms, 350ms for taking 10 photos at each cycle and this cycle repeats. Is it pos...

arm_sqrt_f32 and arm_math.h

Hi, I'm using Cube and Makefile.I'd like a clearer run through of how to make use of the sqrt f32 function in arm_math.h.. The header doco says to copy the header to Include, done.. Then link the Lib for big/little endian. Here's where I'm stuck, how...

We are using HAL library for F215xx and F746xx MCUs. We found difference for CAN driver within HAL_CAN_GetRxMessage() function for setting the RTR (remote transmission request) register. Are more detailed information about sFIFOMailBox availalbe?

STM32G4xx process technology (nm)

Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...

Resolved! Failing to receive data on MCU set up as SPI slave

Trying to receive data on MCU (L432KC) configured as SPI slave. I have tried using interrupt and DMA, but no luck. I have set up the circuit like this : 1 MCU acts as master sending 1,2,3 every 500ms interval (I hooked up master lines to scope and th...

Tracking an optical encoder overflow and underflow

I'm using an STM32F407 MCU with a 600 PPR incremental optical encoder. The encoder is coupled to a stepper motor that drives a 5mm pitch ballscrew. I'm trying to keep track of the encoder count to determine the absolute position of the spindle attach...
