I think I've set up everything sensibly via STM32CubeMX to get HAL control of the LSE, but the external oscillator appears to be not operable. In particular, there is essentially no voltage on the 32kHz crystal pins, so of course it will not oscillat...
I've been a month trying to get connected to Truphone and have gotten nowhere. I have not found any AT command documentation on this site, where is it?So many questions but running out of time...
Please help me with operation of the FMC module in STM32F407VE. It is necessary to connect external RAM memory; since FMC module in this microcontroller uses the address bus and data bus in muxed mode, its need to demultiplex this signals. For this p...
I have a hardware that have on stm32g071 chip and mcp9700 temperature sensor. I tried reading temperature and i read 2040.(ADC 12bit resolution).I also measured directly on hardware using multimeter and i read about 0.7 V So ADC measures wrong. Addit...
We're investigating replacing some STM32F105 processors with STM32F107 on a short time frame.The datasheet footnote says "SPI2/I2S2 and I2C2 are not available when the Ethernet is being used." Does that mean that I2C2 is never available or that you h...
Are these registers two address of a I2C slave or OAR2 is a mask of OAR1?Mean:address slave = OAR1 AND OAR2. Ex. OAR1 = 0xE0 OAR2 = 0xF0. (OAR1 AND OAR2) are 8 address 0xE0,0xE2 .. 0XEE . Thank you Marco
I'm setting the FM_MODE bit in SYSCFG.MEMRMP and I get a hardware fault indicating attempted switch to invalid state.
Hello everyone!I would like to know what requirements are needed to work with sensors in a STM32 core F401RE using I2C Interrupts, and if that is possible.Thanks.I was searching in Internet but I don't find nothing.
Hello,I found this issue that seems that I still can't find the reason.I am using a STM32F750N8H6 (7BA3Z 9R 1), BGA package on a custom 6 layer board.I manufactured 11 boards, and within those 11, 8 of them the HSI seems to be at 18Mhz although the H...
I am using STM32F746G discovery board.~~~void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { HAL_UART_Receive_IT (&huart6, Rx_buff, USART_RX_BUFFER_SIZE); HAL_Delay(500); HAL_UART_Transmit(&huart6, &Rx_buff, USART_RX_BUFFER_SIZE, 1000);}~...
