STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
We are not completly sure how it works. We want to make a receiving module reject some ID's and only approve some. The code we used just approve every ID. Can someone explain how the ID works within our code? (If we for example would like to approve ...
Hi, I have a problem with a STM32L476RG.The problem is UART interface in DMA receive mode, at the beginning of my main function, after having initialized some variable, I call the function: __HAL_UART_ENABLE_IT(&huart3, UART_IT_IDLE); HAL_UART_Receiv...
When reading the I2C bus with DMA it is followed by a NACK. Do i have to clear it somehow in the DMA1_Stream0_IRQHandler ?
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...
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...
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...
I am looking for an expert to help me with I2C bus on STM32F407IGT. I2C3 is working as expected and I would like to make working also I2C1 and I2C2 which I have problems with.I am using the same initialization regarding registers and I can see the ri...
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...
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...
