Hello, I am recently getting back to ST discovery boards. I cannot seem to find the schematics for STMf411RE, I have only found VE that has a different layout. I am trying to bare bone control the LED Thanks
Hey All,I made my first STM32 board using STM32G0B1RE, it arrived today, since it's blank I expected the MCU to jump into bootloader and start the DFU, however this did not happen, MCU was not detected at all by the USB, I checked further and USB DP ...
I have a STM32F303 connected to a L9616 as displayed below. The pullup resistor R3 is not present any more. Please ignore it. Vdd is 3.3V but, as can be seen, I have set Vs to 5V, believing that was necessary to make the CAN BUS work. With an osci...
I tried to enable RXNEIE with following code: USART2->CR1 = (USART_CR1_TE | USART_CR1_UE | USART_CR1_RE | USART_CR1_RXNEIE); But when I checked CR1 register, it's still set to 0: gdb: x /8ub 0x40004400 0x40004400: 45 0 0 0 0 0 0 0 I checked the manu...
I am trying to build a uart implementation from scratch to learn the Stm32, but such a code implementation seems to cause my Stm32F030 to go into Reset_Handler state.What might be wrong with my code? Thanks in advance! void uar2_rx_tx_init(void) { ...
Posted on August 05, 2017 at 04:09Hi,I'm working on a project which should communicate with a camera (canon, Nikon ....) and should be able to get pictures from the camera through Usb port.i search in the net for a way to do that and i found that th...
HiI use STM32H7 with free-rtos for my projct.I need to synchonized analog samples reading from 2 DMA channels and from 2 different ADCs.I use the xEventGroupWaitBits function to stop the execution of the sampling before starting a new sampling cycle....
Hello,I would like to use TCXO (25 MHz) for timing STM32L071. It doesn't really work for me. When I put a scope probe behind C1, a signal can be seen in the picture. (some 27 Hz). Do you know what's wrong? The power supply for TCXO is 3.3Please any i...
hello ,I use stm32h750vbt6I'm trying to send data with spi 16 bit data constantly, I checked the reference manuallyBut there were some parts that I didn't understand. To send 16-bit data at intervals of a certain time, tser,tsize and what should my F...
Hello everybody,for my current application I would like to disable the prefetching of the OCTOSPI peripheral.I'm using a STM32H723VGT6. Ideally one can configure it to be in memory mapped mode but still do every transmission without caching or prefet...
