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);}~...
When I use the 51 kernels, if I encounter too many defined variables, especially when there are more arrays, I can use xdata,idata to define variables, but I don't know if I can use them with STM32?
I'm new to STM32. I want to learn the architecture of STM32 using assembly language. but Keil microVision MDK-ARM is not Linux compatible. What is the alternative of Keil to write an assembly code for STM32.
