I need sine modulated PWM during +ve half cycle of sine wave and zero output during -ve cycle of sine wave. Desired samples of sine are 200. I have attached the MATLAB simulation circuit snapshot. Problem is that I am getting 5Hz freq.
Hi Thank you for having me here! I come from the AVR-Mega community and wondering about selecting a STM32 MCU. I needed more time to process between my input capture and USART and HDLC processing. Which MCU have 4 timers and input/output capture avai...
on stm32f105 launched CAN. With the transfer of messages, there were no questions, but there were questions about receiving messages from two CAN.the code is responsible for processing the messagevoid HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeD...
Hi STM32 community,I'm trying to process a UART string and interrupt when the full string is received. I'm having trouble receiving anything at all. To check that my serial terminal (PuTTY) settings are correct, I have tried HAL_UART_Transmit_IT(...)...
I am using a STM32L475 and plan to also use an STM32L451 processor, I am having trouble setting the RTC so that its in 24 hour mode. According to the datasheet setting a 0 to bit 22 of RTC_TR should set it into 24 hour mode but this does not seem to ...
Hi I am fairly new to SPI slave with dma on a microcontroller, I am wondering in firmware what is the process of implementing it? I have set spi1 up as spi slave and assign dma streams to it in the cubeide, but now that it is set up, how is the data ...
If anyone has a working support number would be a big help. My Question is on the STM32F411 the data sheets state many of the lines are FT 5 volt tolerant, other team members don't believe this and want to use level shifters, they believe as many l...
Hi,Im using the System Workbench and a strange behaviour occured to me.When a certain halting point is reached, Im not able to step to the next one. Pressing Resume brings me back to the very same halting point, stepping over aswell. And stepping int...
Hey,I tried the SSL_Client mbedtls example program for the STM32f7 and I get following error:Handshake failed 0x7780Im trying to connect to a cloudflare server via https. Any ideas what the problem could be?thanks in advance
Simple question: is this possible without additional HW logic? I have these two 16-bit SDRAMs and I'd hate to use just one of them or to use them as measly two 16-bit SDRAMs. I think I've browsed through all 3200+pages of reference manual and couldn'...
