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...
I am testing the RAM code in assembly, function name is ML_RAMTest and it is ended with instruction .size ML_RAMTest, .-ML_RAMTest. It is compiling but encounter with the Error: .size expression for RAMTest does not evaluate to a constant. Can you pl...
Hi All, I am trying to use STM32F401 NUCLEO Board to talk to ST IMU LSD6DSL. LSM6DSL supports burst mode read, but I can not find a way to implement SPI burst mode from the stmf401 s library. I am wonderinf if there is any way to implement a SPI bur...
Hi,I am using stm32l431 and work with LPTIM in stop2mode. When the mcu wake up after stop mode, i2c stop working, so I need to restart mcu.It's strange because in some cases the i2c work in the next 3 wake up, but after this dont work anymore. Should...
Hello everyone,I've just realized a PCB using STM32H7A3 micro. But at second step I already fell.I've my system powered up at 3.3V from an external circuit. The quality seems to be good.I've tried to program the micro using STlink through a SWD port....
