Hello all,I'm trying to communicate with SRAM device on my board.I'm using STM32H747XIH6 MCU.I tried to capture the Write enable, chip select and output enable pins on the board but I saw an unusual response of the output enable.My configuration for ...
I want to use the STM32F769I-EVAL Board to monitor a CAN netork. I configured the CAN module as it has been shown in the CAN_Loopback and in the CAN_Networking example.The Loopback Example does run on my eval-board. I take that as confirmation, that ...
Hey there,I am trying to replace an STM32F767 with an H723ZGT Nucleo Board. The projects uses a lot of heap - in the predefined memory configuration there is not enough place in the RAM_D1 sector. What do I need to do for changing the available RAM s...
I have not been able to get CAN2_RX0_IRQ or CAN3_RX0_IRQ to fire. CAN1_RX0_IRQ works as expected. It appears that rather than the CAN IRQs firing, the WWDG interrupt is going off for CAN2_RX0 and the DMA1_Stream0 is going off for CAN3_RX0. Neither th...
We have a project which reads CAN data on both FDCAN ports. Bitrate 500 kBit is working perfectly, but with 1 MBit no data can be read. PIN-Speed = HIGH (also tried MEDIUM and VERY_HIGH, but no change)CAN-Clock = 80 MHzWe already tried CAN Bittiming ...
I am trying to trigger every millisecond, or 1000 microseconds, but my counters in the interrupt are seeing 167 interrupts per second as opposed to the expected 1000 interrupts per second.I am reading 6 channels with a sample rate of 92.5 clocks per ...
i am generating a pulse using gpio pins ,how i can change the frequency ?
Hello i am working on a project which is based on stm32f103c8t6 mcu.i face a issue while programming some of these microcontrollers.sometimes some microcontrollers are programmed perfectly while some start giving errors(see attachment).while going th...
If DCache is enabled how then can I update a variable (I think DMA + MDMA) and after processing get results to a peripheral e.g. DAC (again MDMA?)?Do I need to clear cache?Will I still have the speed advantage of caching?I am struggling how to get d...
I'm trying to do a quick eval of a NUCLEO-G474re board for use of the SoC as a product communication controller (I2C, SPI, RS-485, etc.), initially using the Arduino environment for rapid testing. Initial attempt to bring up I2C causes NO activity on...
