Hello, I will use STM32L4R9AI in a battery powered design with PSRAM that powered at 1.8v and flash memory that can work at wider voltage range (in addition to DSI display, RTC, ADC, DAC, USB, I2C) so my power scheme is as following:MCU:VDD : 1.8vVDD...

Hi everyone,I have recently starting becoming familiar with the M-Cortex structure and instruction set ( I was raised on Atmel MCUs in school and this is my first time working with M-Cortex and .thumb instructions) I am trying to learn as much as I c...
Hi, I'm using an audiocodec with a STM32F4011 through I2S interface. I configure I2S to transmit/receive in DMA mode and circular buffer. I need to get an ISR on HalfComplete and Complete transfer.HAL_I2SEx_TxRxHalfCpltCallback is fired on half compl...
I use USART2 for connect whith gsm module.When trafic is big enough some byte in transmitting from cpu to modem can be corrupted.It may be happen one time in few minutes.I see corrupted byte by signal analisator. And the same corruption i see on the ...
So problems with stm32h743VIT6 SPI TX.No TXC/EOT -flag(s). No TX interrupts. No physical activity on pin side MOSI/SCK.Like commented to code: I have tried so many variants of configurations (only master transmitters). I feel I have tried all what I ...
I have inherited code that received 1400 bytes over a 2mbps serial link. I've increased that to 1892 bytes and on occasion (not always, but frequently enough to be annoying) I receive my buffer "shifted" by one byte and a garbage byte for byte 0 in t...
My development board "NUCLEO-401RE" has forgotten the original name of the virtual disk.As a result of various projects, the original name "NODE_F401RE" changed to "NUCLEO".I do not know when.The board is working properly.However, the Teseo-Suite Pro...
int16_t GetTim4Encoder(){ Tim4Encoder = __HAL_TIM_GET_COUNTER(&htim4); //__HAL_TIM_SET_COUNTER(&htim4,0); return Tim4Encoder; }
In a noisy media, I need to receive 10bytes with DMA (about 1Mb). I have set the DMA and its interrupt as shown below:void DMA_Configuration(void) { DMA_InitTypeDef DMA_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE); ...
