Re: nucleo-G474re misconfiguration WS, variant_NUCLEO_G474RE.cpp
Is it not right place to open a "ticket"? Excuse my ignorance, what is PR?

nucleo-G474re misconfiguration WS, variant_NUCLEO_G474RE.cpp
Just noticed, that init config in the variant_NUCLEO_G474RE.cpp has this line: if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_8) != HAL_OK) { same time RM0440 page 98 ( Rev 7 ) says: 4 WS (5 CPU cycles)≤ 170 MHz. I changed my code to: if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FL...

Re: nucleo-H743zi2 LTDC_IRQHandler()
Thanks for reply. Meanwhile I was diging into example code, and connted out this two line: // while(ReloadFlag == 0) { // } It helps me differentiate if uCPU hang up really because of interrupt misconfiguration (seen this millions time with any peripheral) or while{} stucks for another reason. I tra...

Re: nucleo-H743zi2 LTDC_IRQHandler()
Extern C already there, wrap in ifdef tags. I don't understand "extend group". LTDC_IRQHandler must be referenced somewhere, it's not part of the HAL .

nucleo-H743zi2 LTDC_IRQHandler()
I make LTDC running on nucleo-H7, adapted one of the oficial examples for H743-eval. What I can't understand, is why LTDC_IRQHandler never called. Steps I done: (example copy /paste: // Set LTDC Interrupt to the lowest priority HAL_NVIC_SetPriority(LTDC_IRQn, 0xF, 0); HAL_NVIC_EnableIRQ(LTDC_IRQn); ...

Re: [STM32L452RE] analogRead() does not reach max value with VDDA/REF+
Read DS:
https://www.st.com/en/microcontrollers- ... 452re.html
Page 158
Table 79. ADC accuracy - limited test conditions 1
What you observe is normal, offset error. All adc have offset abd full scale (FS) errors, that easy to correct in software

Re: stm32duino and DMA / ADC
:D If 16-bits resolution and high sampling rate required, than you need some mod on nucleo boards: Can you explain why? 1. Ethernet IC on nucleo-144 generates quite high voltage ripple, even ethernet is not activated. My measurements shows about 200 mV p-p on 5V rail when board power over E5V, slig...

Re: stm32duino and DMA / ADC
Yes, sorry, I mean the official STM32 Arduino framework. The Nucleo boards are the H743ZI2 and H723ZG. If 16-bits resolution and high sampling rate required, than you need some mod on nucleo boards: 1. remove ethernet, all jumpers listed in UM2407 MB1364 06.2020 2. bring HSE clock to 8.33 MHz, STli...

Re: stm32duino and DMA / ADC
What is the board? stmduino, do you mean ST official plug-in installed over arduino IDE? I haven't seen examples, except CubeMX https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects and https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM32H743I-EVAL/Examples/A...
