Hello,I have a mixed signal application in development, a home energy monitor, and following on from the recent PCB version's test results on the effects of noise, and after reading this article, I've decided to separate my digital and analog ground,...
Posted on June 18, 2017 at 09:21 Hello i have a program on the 32F030f4p6 chip for testing the system clock frequency. It blinks an LED at about 1Hz. the problem is that when i change the PLL multiplier from 2 to 12 the LED still blinks at the sa...
Hi AllHardware: STM32F302Software: STM32Cube_FW_F3_V1.10.0As below is USB descriptor/* USB Speaker Audio Streaming Descriptor */ 0x07, /*bLength: Endpoint Descriptor size*/ USB_DESC_TYPE_ENDPOINT, /*bDescriptorType:*/ AUDIO_OUT_EP1, /*bEndp...
Hi there,Variations of this question have been asked before, but I have had no luck so far.I am attempting a very simple setup where I am using SPI to write to a display, where the screen does not talk back. I am using SPI1 on the STM32F091 and canno...
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...
