Hello,On my project, I use FDCAN1 and FDCAN2. FDCAN1 is working perfectly fine.On FDCAN2, I can transmit data successfully (with the CAN ID 0xBEEF), but when I want do receive data, the Rx callback is never called, nor the IRQ handler (the CAN ID fil...

Hello,I'm a bit confused to how use the VREFBUF on this MCU.I want to use the internal voltage reference (SCALE 0 : 2.5V) for better ADC accuracy.Do I have to connect the VREF+ pin (20) to AVDD (+3.3V) or I've to connect it to a 1uF + 100nF capacitor...

Hi,I'm really struggling to implement easily a GPIO function, even with the tutorials provided.I'm trying to use the GPIO class set (GPIO_ID id), but how ?It's not very well documented, there are no examples provided.https://www.touchgfx.com/document...

Hello,I'm trying to setup a simple example on my STM32F429I-discovery board, but i'm experiencing issues with some graphics (images).I had setup CubeMX using this guide : https://touchgfx.zendesk.com/hc/en-us/articles/360021620431-Configuring-STM32F4...

Hello,I'm trying to have complementary outputs with dead-time on CH1/CH2/CH3 and CH1/CH2/CH3N using TIM1 and Output Compare Mode on STM32F429.So I configured STM32CubeMX like in the picture below :And there is the portion of my code :(for testing pur...

Yep, the callback is well implemented.I finally found the solution : I had to offset the RAM with 14 words to make the FDCAN2 working.Now both FDCAN1 and 2 are working well.Thank you anyways for your help 

Interesting fact : FDCAN2 Rx callback works when I disable FDCAN1, that proves that the hardware is okay and the filters are set correctly. Somehow FDCAN2 Rx callback don't work when the other FDCAN1 is enabled, I'm really struggling with this issue.

Pin 20 is indeed VREF+ on the STM32H750VBT6.I've to try this.Thanks for your answers 

So that VREFINT voltage is set to 2.5V with SCALE0, connected to the pin 20, filtered by the 1uF+100nF external caps connected to this pin, and then the ADC uses that VREFINT for its reference.I'm correct?

Damien Ratazy · 2024-06-24

Okay, and apart of the CubeMX config (VREFBUF = Internal Voltage Reference with SCALE 0), does the ADC automatically choose that VREFINT reference voltage without any supplemental software/register manipulation in my C code?Thanks
