Problem useing SPI together with UART as SPI

As soon as I add USART initialization, SPI starts sending data using LSB and receiving with MSB(as it was intended) bit order.SPI init code:/* SPI configuration */ SPI_DeInit(); /* Initialize SPI in Slave mode */ // SPI_Init(SPI_FIRSTBIT_LSB, S...

I am trying to rebuild my project.stw with the cosmic c compiler, but it is stuck at compiling stage. It was working fine, and suddenly it couldn't compile. When I try to compile the c files in cosmic it shows another error as shown in the screenshots.

Hi Iam student and I now only about Arduino but now I have a project to be creat by using stm8s001j3 so please help me how to connect my STM to Arduino IDE specifically stm8s001j3 and how to use its I2C ​

STM8L051F3P6 Power-up grey zone

I'm finding a window between 1.47V and 1.5V where the device is consuming 1mA (as opposed to <50uA) this is only apparent when the voltage is rising and I assume the device trying to power on. The documentation states it has zero power on reset but t...

STM8 UART1 in half-duplex single-wire mode, switching between RX and TX

I am using a NUCLEO-S8208RB to develop UART1 communication in half-duplex, single-wire mode. The device receives messages (packets of bytes) using the UART1_IT_RXNE_OR interrupt. The next step would be to transmit a byte packet in response, without a...

Hi, in SPI it seems to me there is no difference in the way we configure Full Duplex or unidirectional Transmit-only mode. If there is a difference how can I configure one and other?

When in unidirectional Transmit-only mode, how can I use MISO pin as generalpurpose I/O whithout disturb the SPI?Thanks for any help

IdeaSTM8 - all source files turned red in Fileview/Source Files list. Can no longer compile. Any idea on what I need to fix?

I have used IdeaSTM8 for 3+ years with great success ... but this morning my project wouldn't compile, appearing to indicate that all functions were undefined. The only anomaly I see is that the Fileview / Source Files list has turned all my .c files...
