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...
I have implemented a small I2C driver for stm32l432kc board and tried to use it to read from a couple of MPUs I have first:I can read single WHO_AM_I register correctly giving 0x68 asserted in the debugger I can write to the POWER_MGMT_1 register to ...
RTC code is not working properly while VBAT is connected to a 3v coin cell, it only retains time from the last value but not incrementing as the time increases please let us know what's wrong with the codeI'm following this below linkhttps://www.micr...
