I have to port an existing I2C API to the STM32H743 using the LL drivers. One of the functions must perform the START, issue the address of the slave, then return control. Then another function will send the data.The fact is that when I initialize th...
I'm seeing a strange issue with the Quadrature Decoder functionality with TIM3 and TIM4 on STM32L151 (also seeing the same issue on a NUCLEO-L152RE). Sometimes when the count decrements to zero, the counter doesn't reload. Sometimes it does, picking ...
using the ref code : https://github.com/ARoozitalab/ELM327-OBDII-STM32 , Succesfully compiled & flashes to Stm32f103RC using keil , Could someone help to debug this code, As i checked, in blu.c file, In BLE_recieve, there is usart_recieve function, ...
My understanding of a non-blocking function is that the function will return immediately, and it is up to you to use a callback or other method to collect the data. With FreeRTOS it's not difficult.Yet HAL_FMPI2C_Mem_Read_IT() seems to hang around an...
hello,I have question about adc on stm32.If Vref is connected to Vdd, VddA is slightly smaller than Vdd, ADC might be inaccurate?I just became to konw that our hw-engineer did mistook on connections on stm32.( I found that 1.he connected vdd and vref...
Hello everyone,I'm having some trouble using the ADC in the STM32U585. I developed my own PCB where the MCU's VDD and VDDA are connected to 1.8V. I need to measure about ten analog signals. I have two main problems. First:VREF+ = VDDA = VDD = 1.8V. W...
Hi,I wanted to code an application where the external interrupt would stop the motor. I am gonna be using two limit switches - one with rising edge trigger and one with falling edge trigger.Unfortunately, none seem to work. Please help.I have attache...
HelloThe Flash (MT25QL256ABA) is connectd to the STM32H743ZI (Nucleo) via SPI_3 and DMA. Send and Receive buffer are part of the SRAM3 area. There is no cache enabled.To erase the flash the following procedure is done:Send Write Enable Command (HAL_S...
I needed help getting started with Stm32 L496 processor interface with IS29GL064 nor flash mem. It's my first time interfacing with any external memory. I have decided to use FMC controller to drive this flash mem. But unaware of how to setup the co...
Hi, I am using cubeMx generate the STM32F302VE project, which for receiving the usart1 date by DMA circual mode.My config as below:enable DMA, but disable DMA interrupt;enable USART1, and enable UART_IT_IDLE;Now, the project can enter the "USART1_IRQ...
