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...

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...
