need help designing a car CAN sniffer using STM32 446RE and MCP2551

i have written a simple program that should send "NO MESSAGE!" to the terminal if there are no CAN messages or "A NEW MESSAGE ARRIVED!" and then the CAN message itself through UART2. My idea is that since all car sensors are connected to the same CAN...

Current consumption in STM32L072 very high

Hi guys!A have a problem with power consumption, when I try to put the microcontroller in low power sleep, the current consumption is around 8.5mA, when I expect around 20uA.I'm using a custom board, but only a single LED is connected, capacitors and...

CAN module stops working in STM32F205 from power on to 1 hour with No can data feed

HI,  we are using STM32F205ZGT7. we are using CAN channel 1 for exchanging the information's in vehicles. During our in house testing from power on to about 1 hour the MCU CAN module stops receiving the data after long inactivity time of about 1 hou...

Generate a frequency burst

Hello,i try to implement a 40kHz frequency burst with my NULCEO STM32F411RE. Until now i toggle the GPIO continuously in the HAL_TIM_PWM_PulseFinishedCallback function. But now i have to implement a start Trigger to do a small 40kHz burst. In the att...

STM32F407 RTC skips a second on subsecond rollover

It appears that there is some unusual behaviour taking place when I read the time shadow register from the RTC. My application reads the RTC every 1000 systicks and prints the information.When the subsecond component rolls over to greater than the s...

I want to use NUCLEO-H745ZI-Q to Connect SDRAM by FMC . But this Development Boards has 144 pins, it not has from FMC_A0 to FMC_A12 pins, and FMC BA0,BA1.So what should I do? Thanks

Are the 6 fast channels on an STM32h742 ADC preconfigured by default as fast or I need to configure them as fast?

I have the package LQFP100, so the Application Note specifies that there are 3 fast channels, but the Reference Manual says that the first 6 input channels are fast channels. How is this? If I have to configure them as fast how can I do it or where c...

IS STM32 chip producing now?

Now in China, all distributors don't have STM32F105RBT6, but if we ask from sub-distributors, most of them have massive in stock, just the price is very very high, about 14usd. So, please tell us when the supply can be normal, because if we switch ch...

When I start STM32G031J6(SO8N) PWM, the code jumps to label "Reset_Handler".

I generate the STM32 Project and define each PIN.PIN1:GPIO_OutputPIN4:TIM2_CH1PIN7:SYS_SWDIOPIN8:SYS_SWCLKAnd I let a code below run but it do not reach "while".​ /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_TIM2_Init(); /* USER COD...
