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...
Hi there,I am trying to extend an SDRAM(W9825G6KH-6) for my homemade board with STH32H743IIT6.According to the SDRAM datasheet:I want to set the FMC clock to 130MHz with CL=2.So the MCU clock config is as follows:and according to the SDRAM datasheet:...
Hi everyone,We are trying to program the MCU flash memory to write and save some data on it.After successfully writing to a single sector, we can't delete the sector content anymore.We are using HAL_FLASHEx_Erase to delete the sector.In particular, w...
Hi,I use a STM32G030. The application works fine when we compile it with option -O0 (no optimize).It fails when we using the function HAL_ADCEx_Calibration_Start() for the calibration of the ADC.This function returns the fail at the follow location:T...
I have tried normal GPIO setting with pullup/down and setting AF5, but it just stays the same level, but its shape changes (see additional pictures).I have just connected the probes. (MISO is blue) // *** SPI *** // NSS (PB12) GPIO_InitStruc...
