Hello, I have a CAN 2.0 network (classic can) running at 500 kb/s. I have multiple STM32F4 nodes running the stm32 HAL CAN driver with no issues. I have another node running a STM32G4 with a FDCAN driver set to classic mode. When the G4 node is co...
Hi everyone,I am trying to power my NUCLEO-H563ZI with an external power supply. I have tried everything in the documentation (jumper positions and pin connections) including a 3.3v input (3.3), a 5v input (E5V), and a 9v input (VIN). None of this wo...
Hi, I`m new to MIPI DSI, and still learn how to use it.Recently, I develop with my custom board and start with MIPI interface display. Then config with CUBEMX, but after compile program, it always stuck in HAL_DSI_Iinit while loop below /* Ge...
I am unable to get the I2C line on my STM32H750VB to connect with my PCA9685 PWM driver on my custom PCB. The I2C line is constantly high, which I have seen on multiple oscilloscopes. I got the software online from a tutorial on the PWM driver and wa...
how can i connect the module wifi esp8266 nodemcu v3 with stm32l476rg?
I have tested the POC (Proof of Concept) by using 'Nucleo-439ZI' evaluation Board. I am now going to use the same schematics as reference for my prototype and create a custom board by removing the Morpho and Zio connectors as well as the unintended f...
Device is STM32F765VI.I'm using DMA to fill data allocated from DTCM, for some reason this seems to be caching.My understanding is that DTCM doesn't need cache management, help me if wrong here. If I don't enable the data cache everything works as e...
I think I may have found a bug with the STM32G4 RTC that I am not seeing in the errata.I am using the RTC on STM32G4 with a 32.768 KHz LSE oscillator. I am having a issue where I would read the RTC twice fairly close together in code. I observed that...
Hello, i am interested in the input structure of the NRST pin of the STM32G0x0 series. The datasheet shows a reduced diagram. My question is: is there a more detailed version of the input structure. Is a clamping diode to Vcc build in? If so, which ...
Hi everyone,I'm using the STM32F407 for CAN Communication with the Loopback Mode. I'm trying to send a cyclic frame using a timer.I'm using the timer2 with a clock of 84MHz (APB1), a prescaler of 8399 so i will have a tick every 1ms and a period of 1...
