Hi All,This is not really a specific STM32 question I suppose, so please excuse what might seem like a simple maths question for some of you. How can I do a 1/x operation to a FLT number without using the VDIV command?VDIV takes 14 clock cycles to ...
Hi!I'm doing SDADC and I think there is some issues with the DMA for SDADC in STM32CubeIDE 1.7.0.First, I have enabled DMA for SDADC1, SDADC2, SDADC3 and I have selected InjectedConversion = ENABLE. Then I run this function. volatile static int16_t S...
I have a problem transmitting a byte with SPI using DMA and asking for your help to solve this issue.Used uC: STM32F405RGT6Target: Display ST7789Project generated with STM32CubeIDEToolchain/IDE: Keil uVisionSPI 2 used/configured as "transmit only, ma...
Hello,I am new to ST development ecosystem. I want to use the sample applications(specific to a dev kit) provided as part of the cube expansion packages for our custom board. Any help on the steps or a reference to a document on tweaking existing app...
Hello, I have a power converter device controlled by a STM32L475RC. One part of the control requires a constant PWM of 70kHz of 300ns (Ton). Although this pwm is never modified,and doesn't use interrupts or DMA modules, periodically it produces a gl...
Using Nucleo-L476RG board with I2C. Using a logic analyzer i'm getting meaningless signals as seen in the image. SDA AND SCL are connected to pins PB11 and PB10 respectively and are connected directly to the logic analyzer block directly to monitor t...
It is like DMA never starts.Any ideas?below is the code./* USER CODE END TIM6_Init 0 */ TIM_MasterConfigTypeDef sMasterConfig = {0}; /* USER CODE BEGIN TIM6_Init 1 */ /* USER CODE END TIM6_Init 1 */ htim6.Instance = TIM6; htim6.Init.Prescaler = 42-1;...
I have sigma delta 16-bit ADC enabled. It works great with regular interrupt. No problem there, but when I'm trying to use DMA with Sigma Delta ADC, then nothing happens. It will only be zeros.I have 9 SDADC zero referenze on SDADC1, 3 SDADC zero ref...
When flashing a bin file to a blank/erased STM32G070 the --reset option does not consistently reset the processor after flash. The first couple times I did this it worked. Now it is not.A snippet of the output from a failed example using the command ...
HelloOur new product use a STM32F427 and a ADC(AD7768-4) the data input connection is the SAI(serial audio interface). The STM32F4 SAI mode is the slave mode.The ADC sends SAI_SD signal and SAI_FS at rising edge.Therefore, we think that the STM3...
