I am developing a device which needs to continuously monitor noise (buffer / page to memory) and either Once or 8 Times per second analyse the acquired data to provide the following:FFT CPB (single or 1/3rd octave band analysis)Various over-all and ...

Pretty frustrating experience so far. I have seen many people asking but no-one has a straight answer. Very simple question, these are my steps:1- Started Cube32MX, selected NUCLEO and reset all no essential pins. See photo. 2- Clock configuration is...

Just working on some audio projects and purchased the CCA02M1. I can't find any documentation confirming that the H7 supports this expansion card. Nothing on Google so asking here. Second question. My NUCLEO-H743ZI cannot be connected to the CCA02M1 ...

I have managed to get ADC working in Interrupt mode and can read the three sensors values into a buffer called ADC3_VALUES[] on each of 3 callback events triggered by the ADC..../* USER CODE BEGIN 1 */void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* ...

Whereas selecting v1.3.0 downloads the full ~400Mb file. Anyone else having this problem ?

Thanks Eleon, that makes sense. The application is industrial and runs on 24V DC so no power issues. I am liking the digital microphones for their ease of use and dynamic range. Would be nice to have them packaged in a conventional 1/2" cartridge* s...

Hi. How did you go with this query ? I am just starting a project now and will be using this microphone on a NUCLEO-H7. Also have an L4 like yourself.

OK... another tweak and now it seems to work. Changed the PLL Source MUX around so System Clock driven by HSI.... ... and now we have 400MHz clock running and print(f) working also at all above speeds.... not easy

Still completely up in the air on this one. Using this code in main.c... uint32_t SysClk; uint32_t HClk; uint32_t PClk1; uint32_t PClk2; SysClk = HAL_RCC_GetSysClockFreq(); HClk = HAL_RCC_GetHCLKFreq(); PClk1 = HAL_RCC_GetPCLK1Freq(); ...

Succeeded in getting 128x64 parallel GLCD working on the H7. Took a lot of trial and error. It is very easy to go down rabbit holes with this technology and as someone pointed out once, there are so many variables and gotchas with interfacing that on...
