Please let me know if there are any hardware or sofware specifics for connecting TCXO to the STM32G474 series? What should pay special attention to?I use FT2MN at 40 MHz. Its output was connected through a 10 pF capacitor and a 220 Ohm resistor, in s...

Hello,Can anyone suggest whether or not I need to connect external capacitors to the VREF+ pin if I plan to use VREF only for the onboard DAC?Could this be a hardware problem?STM32G431CBT6. The problem is that on the oscillogram I see oscillations wi...

Thanks to everyone who responded.In this case, it was my mistake with the choice of the generator. I mistakenly perceived 0.8 Vp-p as 0.8 V from the supply voltage of the generator. But it is not so. This is exactly 0.8 Vpp (peak to peak). Abrakon re...

I am already in contact with Abrakon, as soon as it becomes clear I will share.It seems to me that the problem is the low amplitude of the signal at the output of the generator. Even if I disconnect the generator from the controller, the amplitude re...

My post from 2024-09-20 08:15 AM I get to line 25 from it I get to the error handler function itself. There is a loop.

Here I get into an error handler. if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); }

If there are experts here on board tracing, please tell me whether such a board layout can affect the operation of the generator (at a frequency of 40 MHz)? Underestimate its amplitude. Textolite 1.6 mm, red upper layer, blue lower layer. The filling...
