Hi all,I'm using MCP2515 for a CAN application in the NUCLEO STM32WL board. I've managed to get it to work in pulling mode, however, I want to use interrupt mode. For what I looked, I just have to enable the MCP interrupt pin in EXTI mode in cubeMX, ...

Hi all,I want to increment the lap_marker variable only once when the lap_button is pressed, but when I press the button, it increments multiple times, untill I let go of the button (when I put a breakpoint in the loop it works fine).I only want to i...

Hi, I'm using the APP_LOG function to print data to serial. Here's how i do it:APP_LOG(TS_OFF, VLEVEL_L, "%d,%d,%d,%d,%d,", front_brake_pressure, rear_left_wheel_speed, rear_right_wheel_speed, front_left_wheel_speed, front_right_wheel_speed);APP_LOG(...

Hi all,I am receiving date and time by CAN for my application, and not using the RTC functionality because I couldn't get it to work with LoRa.Basically I receive day and month separately, and declare the year as a int. Same thing for the time, I rec...

Hi all,I'm trying to use Timer16 to create a 50Hz timer to save files in the SD card. I managed to make the timer work blinking a LED, but when I put the code to save it only saves one line. Here's the logic:First I create a file and initiate the ti...

Also don't know, here's the schematic on the board (consider PA0 as PB14 (CAN_INT_Pin))

I don't think so, at least not in the main code. The callback code follows:void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if (GPIO_Pin == CAN_INT_Pin) //MCP2515 Interrupt Pin { //CAN receiving messages (Packages MUST start from the small...

Hey, just updating.I changed, the pin I was using for the interrupt. It is connected directly to the interrupt MCP2515 IC pin. I pu the osciloscope on the pin, and couldn't see nothing, only a voltage offset.What could it be? I need to do something e...

Ok, so if I just remove the SB16 solder, the PA0 pin would be available to use on the MORPHO connectors, or simply just use the PC13 pin, right?

Here's the schematic of BUT1 pin. I'm not sure if the PA0 bypasses this connection, or if would only work if the button is pressed
