Hello,I'm working on my customized board with STM32H747XIH6 MCU which is connected to the DPRAM (Part No: 70T653MS12BCGI). The connectivity is as follows.While I'm trying to read and write from the DPRAM after 22 locations the software hangsI have at...
I have an A/D circular DMA that collects 192 samples...There can be times when an asynchronous push button event interrupts this while it is collecting. Can someone tell me the quickest solution for resetting the DMA so that after I service the push...
Hi AllI have a problem with RS485 Communication. I am using STM32f103rbt6. Only send a struct data (13 bytes). Microcontroller send this data to ADM4855ARZ (RS485 IC). Data sends correctly ( ı checked with logic analyzer). Than this data goes RS485 t...
As you can see in the above image, I'm trying to design a motor controller. But pin 16 of L293D requires a 5v input as VCC1 but the maximum output a STM gives is 3V. I wanted to know how to convert and map the 3V to 5V using a passive component?
Hi!we use STM32G473 with 4 timers for 2 motors, for each motor we use 2 timers connected with ITR , the first timer is used as encoder input to hold the position, the second timer interrupts on each edge of of the encoders and calculate the speed.Wh...
Hi,I have STM32CubeIDE 1.7.0 issue whereby I can connect either ST-Link V2 or V3set to our custom board that has STM32L462RET6 MCU. Same with STM32 Cube Programmer - can't connect - target not found. Inside IDE, there's problem launching GDB serv...
I am using the Audio Playback and record exaample.I modified Systeem_clock_config as follos /* Enable HSE Oscillator and activate PLL with HSE as source */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_LSI | RCC_OSCILLATORTYPE_HSE; RCC_...
I want to made a simple Voice Recorder and Player Module, i found an interesting article here:https://community.st.com/s/article/how-to-play-audio-files-using-stm32-part-1?t=1675535162773 But it´s focused to STM32G0, and i have stm32f401, i´have trie...
Hi , I am using DMA/serial port transfer with RTS /CTS handshaking to transfer between 490 and 506 bytes from variable dma_buffer. The byte stream is terminated with \r\n\0 . the code is below : while (transmit_complete_flag !=1 ){;} // wait here un...
