Hello,i have a question concerning the SD-Card functionality and the licensee fee of the SDMMC implementation of the STM32H723ZG.My goal is to log some data on the card. According to the documentation, the FatFs-Filesystem can be used under a BSD-sty...
Hello,According to the documentation, the FatFs-Filesystem can be used under a BSD-style license. How About the exFAT licence fee. Has this fee already been paid with the purchase of the STM32?
Hi there,There are a few projects where having a 16bit DAC instead of a 12bit DAC would be extremely useful.I am currently using the G4 series as analog synthesizer controllers and it would be fantastic to be able to use the 1MHz DAC as a 16bit audio...
Hello,We are working on an induction heater design using an STM32G4 MCU, where we need to measure the coil current via the ADC. The system operates with a half-bridge switching frequency of 30kHz.At lower frequencies, the current waveform is triangul...
I've been designing STM32F devices for 15 years.My first design using a "G" family - and it has NOT been easy.SPI is a very simple device to use - my setup: RCC->APBENR2 |= RCC_APBENR2_SPI1EN; RCC->APBRSTR2 |= RCC_APBRSTR2_SPI1RST; // resset...
I am writing a field oriented control library targeting the STM32F4xx and STM32G4xx series. In the program, I have to: 1) Read 2 sensors using I2C 2) UART serial communication with host PC to send real-time motor parameters or receive new commands 3)...
I'm running the ADC on STM32G071 and I am seeing double spikes when the ADC takes a reading. Any idea why there are two spikes? I expect to see just one. Below you see two spikes followed by another two spikes 1ms later. My software starts an ADC rea...
i want to read every 10 seconds a few samples from a adc channel and let the dma bring the data to my variables.i have that working with 1 sample. the timer trigger the adc. adc trigger the dma channel and my HAL_ADC_ConvCpltCallback get called and t...
It's my first time on a project where I need to consider "high-speed" signals, I read up on it but I am not entirely sure if I even need impedance or length matching here.I want to add external SDRAM to my stm32H7A3ZI MCU running at up to 280MHz via ...
Guys, I need help with ADC on STM32F407ZGTx. I have a project where I read 2 channels, ADC3_IN4 and ADC3_IN15. Since I need a function that has pin ADC3_IN15, I changed it to ADC3_IN8.The problem is that I don't know what it is about STM32F407ZGTx, a...
