Hi,I have a problem with CAN peripheral on this board. I tried the CAN Networking Example from the EVAL board and changed the pin configuration to fit to the Arduino connector.I found some possible pin configurations:CAN1_RX on PA11 -> D10CAN1_TX on ...
I have two STM32 based development boards and would like to get CAN example (slightly modified) to work with a simple data packet of 2 bytes sent from one board to the other. But I detect no valid CAN frame on the bus.The setup is taken from here:STM...
Hi, everyone, I have the next problem, I am using the same pins like a simple GPIO output, and like a PWM output.To change the output from PWM to GPIO i using this code: GPIO_InitTypeDef gpio; gpio.Pin = GPIO_PIN_0|GPIO_PIN_1; gp...
I'm using STM32F427.I want to declare the variable as a custom section and use it in a specific address area on the MCU FLASH.I change the *.ld file, declare that the variables are assigned to the designated section, so the compile becomes normal, an...
Hi, our hardware engineer kinda messed up and I'm forced to use an onboard STM32C8T6 and lowball it as a UART "relay", basically UART1 reads whatever that's putting in with likely a buffer of 32 bytes, and immediately sends them out over UART3.The du...
Hello,I'm using an STM32H743-EVAL2 board, I want to access the LCD screen to draw a PNG image, so I'm using a png library to load the image, and this library use "malloc".Unfortunately the RAM of the H743 is too small for handling large pictures, so ...
I'm working with a 24-bit external ADC (LTC2512-24) and stm32u5 (NUCLEO). With the MCU as master, after Data Ready Line (DRL) falling edge from the ADC I need to read 24bits via SPI within 740ns and then have SCK remain quiet until the next DRL falli...
HelloI'm using an STM32L431 and trying to enable character match on usart2MXcube does not manage "MODBUS" modes and the st HAL layer doesn't seem to allow this setting (it allows modbus timout but not character match)So I try to modify USART_CR2 ADD...
Hello I have a custom board with a STM32H753ZIT and I’m wondering about the amplitude of the HSE crystal. It is only 300mV (see the attached Image). It seems to wok but is this normal?The crystal requires a load capacity of 20pF per datasheet, the ca...
