Hi allI have a custom Board with STM32H743 and i would like to add external SRAM and NOR Flash at the QSPI Interface. For example the SRAM at the Bank1 and the Flash at Bank2.Is this possible?I' would like to use for SRAM:https://www.mouser.ch/Produc...
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...
I'm using the Semtech SX1272MB2DAS Lora shield on the SMT32L475 Discovery kit IoT node.ON the Lora shield there is a UART plug which takes a Grove cable. I connected that to a legacy PCB which I managed to operate using an Arduino. It's just a simple...
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...

Hello everyone, im currently studying DMA on STM boards, and im trying to send I2C messages from a mcu SLAVE (arduino) to STM32F407VET6 master, but both SCL and SDA lines is held low, it doesn´t happen when im using I2C in polling or interrupt mode, ...
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...
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...
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...
