Good morning everyone,I have an application where a STM32G474 as SPI master interacts with another ST controller as SPI slave. These are full-duplex DMA transfers of about 500 bytes at 10MBit transfer rate. The slave signals that it is alive via a di...

Hi guys,I have a problem with the internal temperature ADC-channel. I am trying to read a few analog values with ADC1. The ones I read from pins are perfectly fine but when I change the input voltage on PC13 (channel 13) this changes the value read o...

Hello all,I have a strange behavior with the ethernet connection of my STM32F207 application:When I flash the software to the controller the software works. I can ping the controller, I can communicate with a client software to the serversoftware on ...

This is not a solution for everybody but since nothing else worked I switched master and slave.

Yes, you are propably right with the code bug. I am not really believing in a compiler issue myself. This is more of a last hope before I start switching to something else for the communication between the two controllers Regarding the code: this is...

HAL_SPI_TransmitReceive_DMA is beeing called or at least I can see with an LED that the code switches between the part were this function is called and the part were it is not called.After removing> __HAL_RCC_SPI1_FORCE_RESET();> __HAL_RCC_SPI1_RELEA...

@tjaekelThanks for your answer.The Master will not restart. Or at least the master does not start the clock again and therefore as you mentioned will not start driving the MOSI lane. I have currently pulled down the clock to ground. Since this is no ...

Thanks for the quick answer. I am going to try if the behavior changes with longer sample times for the temperature channel and a different sequence of converting

Problem Restarting full duplex SPI DMA on STM32G474

Problem with ADC-Channel 16 (internal temperature) on STM32F207

STM32F207VC - Ethernet with LwIP works after flashing but not any more after power supply is set off and on again
