Hello,I'm using a STM32G431 MCU ADCs in dual mode. I'm trying to get control of the sampling rate and have found a frustrating issue. I don't need to scan multiple channels. Though the only way to get maximum sampling rate, or to have any control ove...
Hello,I setup USART1 using DMA with a STM32G071 & using HAL lib.Currently, i try to send uint8_t TxBuffer[7]={0x16,0x07,0x98,0x09,0x00,0x00,1B}.Transfert is done using HAL_UART_Transmit_DMA(&huart1, &TxBuffer[0], 7) and i have well manage the require...
Hello all, I have an STM32L073 using the HSE to clock and LSE for the RTC. Aalarm A & B interrupt are both activated and the device will wakeup from stop mode by them. It works fine at the most of time, but it returns HAL_ERROR sometimes. I check...
This is probably the promised replacement.[Edit 2023] Link above lead to Ideas, a section mostly ignored by ST (TouchFX crew being exception) and ultimately removed together with content i.e. user wishes when migrating to Khoros [/EDIT] Pity. It's be...

Hi,i have a STM32H743 with an external voltage reference with 2.5V and want to use the internal temperature sensor.When i use the calibration values from flash i converted them by ((TS_CALx *33.0)/25.0).The measured value at room temperature seems to...
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...
