I want to transmit data over fiber optic from STM32H743VIT6. I am using internal MAC of STM32H743VIT6 and LAN8742 as PHY. The ethernet signals after LAN8742 are going both in the RJ45 connector and also in Fiber optic transceiver. I am using AFBR5803...

I am working on STM32H743 MCU. I generated the initialization code used stm32cubemx v5.3.0 and embedded firmware package for STM32H7 V1.5.0. I am using keil uvision v5.28.0.0.I initialized uart1 in interrupt mode. I am receiving data in buffer until ...

I am working on STM32H753 microcontroller. I want to receive string using UART interrupt and send the same string back on UART. The IDE is keil uvision 5. The problem I am facing is that when I first program the MCU UART is working fine and I am rece...

I am using STM32H753 MCU. I generated my code using STM32Cube. The UART is configured to work on interrupt, baud rate is 19200. I sent 'A' many time but most of the time I am receiving "C1" in hex instead of "41" ('A' in ASCII).When I analyzed the da...

I am using STM32H753 MCU. I am using ADC1 and ADC2 and calibrated the ADC offset using auto calibration function. But this function is not working properly. I am getting a difference of 50 counts on subsequent starts of my device. I checked this by g...

So the ethernet signals go to the RJ45 connector (hopefully with internal transformer and termination) and the optical transceiver? YesAnd is that optical transceiver really IO compatible to the LAN chip? Is there any special PHY required for optical...

Hello,>>Buffer needs to hit full capacity before the callback will trigger, you use the same active buffer. - I am only receiving data till '\0' (NULL) is received. Therefore callback will be triggered once NULL is received, which is working as expec...

When I am using a fresh new controller ADC is working fine but after many times programming and debugging the controller ADC is showing weird behavior. ADC repeatability is drastically degraded even after giving a highly stable and accurate voltage r...
