Resolved! Where can i find a repository of startup scripts for the st micros?
I currently am working with a stm32L010K4 mcu, but i have a startup script for stm32l010xB (startup_stm32l010xb.s). Where can I find a startup script for the stm32L010K4 mcu -- I'm guessing the name is startup_stm32l010x4.s ?
STM32 using CAN-BUS.
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 ...
UART Busy before Start.
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...
Resolved! STM32H7 I2C with DMA, no ACK after last byte
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 ?
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...
