My first CAN channel functions like there is no issues, my 2nd CAN channel will never trigger the Rx INT callback. I have it pointed at RxFifo1 but it also did not work pointing at RxFifo0. When I disabled CAN1, and CAN2 became the only Rx, it work...
I had working code on a Nucleo G4 board for CAN so I ported it over to the H723VET. I am running the same clock speeds and have it connected identically to the CAN shield i'm using. The issue is that it NEVER SENDS DATA! I've adjusted the CAN para...
Hi Guys,Quick question. We are using STM32H757Eval board for an application. We are not using in-built DSI display, instead, we use RGB display of size 1024*768. We are using 32bpp and transmitting RGB via LTDC. As per the datasheet, the maximum perm...
I'm currently trying to get a message from another can device and I can't figure out why my callback isn't triggering.I can transmit a message without any problem however I can't receive any. I am using vector CANalyzer to check my bus.I was trying t...
Hello everyone, I am trying to measure how much time is used to finish executing a function. I cannot use the timers because it adds some delay to the system. My other option is to use GPIO pins.To do this, ISET a pin at the start of the functionRESE...
I'm using the HAL_I2C_Master_Transmit_DMA driver on an STM32L412. I am transmitting 8 bytes of data to an external 4 channel I2C DAC - I have only one device on the bus. The first use of the driver works fine as confirmed by using an oscilloscope on ...
Hello ST community,I have QSPI flash and an environment sensor based on SPI with stm32l496rg development board.If I put controller in stop mode 2 without sensor and flash current consumption of system is 3uA.If I connect flash and sensor then in stop...
