STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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); ...
Hi, community:I'm working on a custom board based on a STM32F7 MCU,which I have use the MCU is STM32F750Z8T6 and spi flash is W25Q064AJVSSIQT(Winbond).But the assets (images, font ...) are too large to be loaded into the memory of the MCU and have to...
Hi everyone!i have an issue with communication! As shown below, when I press the green button I want to toggle led on the IoT board & when it’s the red I want to toggle WiFi ble led( I didn’t find an other user led)if i press the red button it works ...
