HI there, I have rewitten this simple piece of code from scratch multiple times with no success. I am just attempting to turn on a set of LEDs. First in the While Loop. Second in the interupt handler for TIM2. The chip is a STM32F411CCU in a homes...
Hi,I am working on SPI communication between STM32G491 and ATM90E26. and I am using the SPI polling API with HAL_SPI_Transmit and HAL_SPI_Receive.My System clock is 96Mhz and I am using prescaler of 64 for SPI.CLKPolarity=Low,CLKPhase=1Edge.Communica...
I have a HAL_SPI_TransmitReceive_DMA() transaction that I am performing. The data can be seen on the line to properly get clocked out over SPI. The problem is that in the receive interrupt, we kick off the next transaction (a DMA SPI write). This wri...
I need to assign 8 GPIOs (4 I/p + 4 o/p) for membrane keypad pushbutton circuit. I am worried about ESD protection of GPIOs. Please suggest STM parts for ESD protection best suited for use purpose.Kindly let know if I can select any pins or there ...
I have spent a few weeks reviewing HAL related and LL related neopixel libs however I would love if there was someone who had a working version of literally just the ability to set up a neopixel on any port and simply light it or light a few neopixel...
Need to use stm32f407vgt6 discovery board to connect with HID card reader via USB OTG.Now I was using stm32 to read keyboard input successfully but I think the HID card reader works the same with the keyboard so I was using the same code but nothing ...
I m using STM32IDE ioc to generate SPI signal hardware NSS, CPOL 1, CPHAS 0 and it was working fine until recently lots of overshoot and undershoot appear, which causes the slave device to fail all data transmit to MCU. i enclosed the waveform, anyon...
I have a STM32WLE5 custom board with MX25L4006E SPI Flash.I created an external loader with CubeIDE based on the article - "How to add your SPI flash into the STM32CubeProgrammer’s external loader"The result stldr does not work and when I tried to de...
Hi Everyone,I'm unable to connect to my STM32F103c8 board using an ST-Link/v2(isol).I connected the cables as mentioned in ST-Link/v2 manual:PIN1 (VAPP) -> VDD PIN7 (TMS_SWDIO) -> SWIO PIN9 (TCK_SWCLK) -> SWCLK PIN20 (GND) -> GNDHere is...
I am transferring sensor data between Jetson Nano and STM32F411E-DISCO via can using 2 MCP2515. On the STM32 side, imu and encoder sensors are connected and constantly transmit data to Jetson nano via canbus.However, due to a problem that I do not fu...
