Arduino for STM32

Is it not right place to open a "ticket"? Excuse my ignorance, what is PR?

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, FLASH ...

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 ...

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 .

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 ...

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

: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 ...

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 ...

What is the board?
stmduino, do you mean ST official plug-in installed over arduino IDE?
I haven't seen examples, except CubeMX
