Zero crossing detection
HELLO, Can you please suggest us any mcu having internal block for zero crossing detection in stm32 for 50 - 60hz frequency signals or any slave chips that are dedicated for zero crossing detection. Thank you, Krishna.

Resolved! USART HAL_UART_RxCpltCallback is not called.
Hello. I am currently using USART6 by setting RX as interrupt, and TX as DMA in STM32F4.The ST board mostly worked well, however, after some hours (maybe 10 hour), the RX interrupt wasn't called. I suppose that this problem is not related to hardwar...
Resolved! The PWM signal that has passed through the level shifter(level converter) is not clear.
I'm using PWM with level shifter(BSS138, 74HCT14D, TXB0104) for developing IC embedded LED (such as WS2812) However, when I captured this siganl using scope, I found that the signal was not clear.Below are the pictures that I captured. 1. Before addi...
STM32H7 SPI using common lines for two sensors and DMA
Hello,I have been working on creating an SPI loop using the SPI callback function to alternate between two sensors that share a common SPI SDI/SDO line. However, I am encountering an issue where the SPI transfer complete callback is triggered, but t...

RGB565 and RGB888 pixel format.
Hi.I am using STM32H7B3LIH MCU and Newhaven "NHD-4.3-800480CF-ASXP" TFT. I completed all the configuration according to the instructions in AN4861. I am trying to show an 800x480 image on the screen using framebuffer. I use "LCD image converter" to c...
Resolved! wrong ADC DMA Continous conversion data order
Hi,I cannot understand acquired ADC data order using this configuration on a STM32G030C6 device:I want to acquire 9 input channels + 2 internal channels (Temperature Sensor + Vbat). Continuous mode w/ Circular DMAHere's my Initialization routine stat...
stm32f373R8T6 spi time setting questions
II am using the SPI function in STM32F373R8T6. When I use the HAL_SPI_TransmitReceive function to send and receive data, I want the to read the data from the slave immediately after sending. However, when using this function, the NSS pin pulls up fo...
