Hello,we currently have a problem using PB6 of an STM32G474ME as FDCAN-TX: During Reset, it is pulled down to GND, which we attribute to the USB-C functionality. This causes the FDCAN-TX line to send a dominant signal during reset of the STM32.As per...
I have a board that is running well. There are about 50+ PCBs in production operating fine. The firmware is pretty complex, but the hardware relatively simple, just some SPI devices and some PWM outputs.I revved the board, and the new board doesn't w...
Hi,I work with STM32F412/STM32F413 processor. I have also external LSE.I have the next problem related to STOP mode and RTC.There are some scenarios we want the processor to go to sleep for x hours.The processor goes to sleep for 5 seconds, doing som...
I've used https://community.st.com/s/article/how-to-create-an-i2c-slave-device-using-the-stm32cube-library as the example codeand in the example the main program is:/* USER CODE BEGIN WHILE */ while (1) { if (Xfer_Complete ==1) ...
I am trying to connect LCD (SPI interface) to my custom stm32f030c8 board, PB13 -> SCK, PB15 -> MOSI (Transmitt only mode).I created a test project with cube configurator (attached a screenshot).I did not change anything in the generated code, just a...
Hi!I'd like to set a custom section in the linker script file to store firmware specific constant data. This section should be at the head of the firmware binary with a fix offset address. I was able to create a section at the end of flash area but t...
I'm trying to create a Synchronous communication using a timer and GPIO.I can toggle a pin-up to 1Mhz inside the main function, but if I try to toggle gpio inside the timer interrupt handler, the max toggle speed is around 300khz. Is there a reason f...
Hi,coudl someone paste simple code to send some bytes between I2C1 and I2C2 on one board?Prefer HAL. I try this: uint8_t data = 69; uint8_t data2 = 0; HAL_I2C_Master_Transmit(&hi2c1, 32, &data, 1, HAL_MAX_DELAY); HAL_I2C_Slave_Receive(&hi2c2, &data2,...
