I have found a few tutorials about implementing a vcom port with STM32, and I could successfully programs (well, let's not exagerate let's say I merely generated programs) working for discovery F407 and F469. I could send a constant string that I rec...
In the datasheet https://nl.mouser.com/datasheet/2/389/dm00440565-1799229.pdfis stated that the uart and the SPI are part of two different alternate functions. The error message and the code will also uploaded if needed.
Hi, is there a way to slow down the DMA speed for DAC? I am using stm32F72x, and I am trying to generate a customize PWM wave from using DMA+DAC.
I get this error in several different codes. Including led blink also.
I am using an STM32L476RG and using I2C-1 and I2C-3 to connect to two different sensors. Both I2Cs have identical waveforms on the SCL and SDA lines when observed with an oscilloscope. This suggested a short to me, but the short is definitely not on ...
How can I get a snapshot from the TTL camera that is wired to the STM32F4 by pushing the user/any button? After the image has been taken, it should be transferred to a mobile device via Bluetooth. I'm newbie and don't know where to start. Looked up ...
Hello, I would like to use three flash memories in QUADSPI from an STM32F7.As with a normal SPI link, I have connected three memories to a single QUADSPI port and select each with the respective SLAVE_SELECT (SS) of the memory.I can easily program on...
I am trying to put STM32H743 into sleep mode using the following codeprintf("Entering Sleep Mode\n"); HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON , PWR_SLEEPENTRY_WFI); printf("Exiting Sleep Mode\n");I notice that my microcontroller dont go into s...
Please find the goals and the issues belowGoal - Start server on 4 sockets one by one, then keep on looking for a client for all the four sockets. When a client is connected to any of the server, I want that server to start sending/receiving the data...
Hi all,I have trouble with receiving one byte on SPI1-DMA1. All is working if I set more bytes to transmit/receive (2 and more) but when I try to send only one byte it do not trigger interrupt on Rx channel (DMA1 channel 2).I can see transmitted byte...
