HiMy stm32l433cc circuit has two different LDO, one for Vdd and another for Vdda. Can you tell me please can i run my controller without Vdda power? I need to turn on/off analog power when i need it. Is it possible on stm32l433cc?
Hello,I'm trying to get data from an external ADC (18bits) with an STM32l476RG nucleo board. There is a lot of overhead and I will improve it later but even the frequency clock is not fast enough. I don't understand why but the maximum clock frequenc...
Hi guys! In my project Im reading samples with the adc at 48Khz using timer interrupts and adcConvCallbacks, load them in a buffer of 256 samples and when the buffer is full I send it via i2s to the DAC . Im using two buffers, when the bufferA is ful...
Hi,With helping of CubeMX I measure voltage on battery (ADC channel 0) using ADC in DMA mode. I also measure internal refference because my VDDA is not know in advance.Once these 2 values are measured I need to convert the RAW data to mVolts.I use da...
Hello,I am a beginner to Nucleo-64 board programming and I am trying to work on USART communication of it. I am using NUCLEO-L476RG board and STM32CubeLL library for configuring USART and starting communication with it. Programming Scenario:I have co...
Posted on December 08, 2016 at 19:01 So I finally got my IL9325 TFT display running via FMC but it is running much slower than I expected. The SPI based displays on arduinos seem to be performing better than this parallel setup. I measured my data ...
I am using a STM32L4S9 microcontroller and used CubeMX (L4 V1.13.0 Firmware) to generate code for the USB to communicate with the device as a serial port. When sending an exact amount of bytes, 832 to be precise, the data is not send through to the P...
HelloThere is a working project of an audio switch made on STM32L452. Then we needed another USB port and additional performance. Therefore, we shift the project to STM32F745. The algorithm works well on the STM32L452. But on the processor STM32F745,...
I use STM32CubeProgrammer software to download SPI FLASH.If there is a program in FLASH of stm32 mcu, the download will fail. If I erase the internal program of stm32 mcu, the download will succeed.
