HAL_UART_Init() bug for more than one UART setting

I am working on a LoRaWAN and GNSS project. I have found one inconsistent operation when try to configure UART1 for GNSS connection. UART2 is used as PRINTF for logging.   Procedure to produce bug: Use I-CUBE-LRWAN example as the codebase.Add code fr...

Invalid SPICE model IGBT STGW20NC60VD.

Hi.Now I am composing the model of the device in the program Microcap using SPICE model of IGBT STGW20NC60VD. This transistor has current-voltage characteristics shown Figure 1. But SPICE model of transistor has other different characteristics (Fig. ...

STM8L1528 ADC, DMA, TImer not working together.

Hi there,I am developing code for STM8L1528 EVAL board. My goal is to configure adc with dma(peripheral to memory) where adc should collect data for certain period, for example, 2 seconds.So I configured adc and dma according to examples codes given....
